      <title>CORRELATION OF FIELD INJURIES AND GM HYBRID III DUMMY RESPONSES FOR LAP-SHOULDER BELT RESTRAINT</title>
      <link>https://trid.trb.org/View/153083</link>
      <description><![CDATA[Simulated frontal, lap-shoulder belted, barrier impact tests were performed using a Volvo sedan and General Motors Hybrid III anthropomorphic test dummy.  Swedish field accident injury data for this vehicle are available from another published study.  For the purpose of this program, the injuries were logically subdivided into four body regions: head, neck, thorax, and lower torso.  The Hybrid III has instrumentation in each of these regions.  The results of three replicated tests at barrier equivalent velocities of nominally 32 and 48 km/h are discussed in terms of the field injuries, thereby providing a basis for more intelligent interpretation of future Hybrid III test results.]]></description>

      <title>A MODEL OF LOWER EXTREMITY MUSCULAR ANATOMY</title>
      <link>https://trid.trb.org/View/203181</link>
      <description><![CDATA[The mathematical prediction of muscle and joint force requires a quantitative knowledge of muscle origins and insertions.  A model is presented based upon marking the origins and insertions in three cadavers (six limbs). Right-to-left biological variations and/or marking errors are sometimes significant, but they rarely result in moment arm calculation variations of greater than 20 percent and usually the variations are less than 10 percent.  The muscle origin and insertion differences between small and large cadavers is great, as would be expected, and the use of single specimen or average data will result in large errors in muscle force predictions.  A scaling scheme is presented which substantially reduces those errors.  The inherent limitations of developing a straight line muscle model include: 1) right-to-left biological variations and/or marking errors; 2) difficulties in establishing "effective" origins or insertions when the locations of the actual origin or insertion do not accurately reflect muscle function; and 3) intersubject variability which cannot be accounted for by simple scaling schemes.]]></description>

      <title>SUSPENSION BOUNCE RESPONSE OF CANADIAN MAGLEV VEHICLE UNDER GUIDEWAY EXCITATIONS - 2. STOCHASTIC MODELING AND ANALYSIS</title>
      <link>https://trid.trb.org/View/180911</link>
      <description><![CDATA[In the investigation of the Canadian MAGLEV vehicle covered here, the vehicle was subjected to a combination of periodic as well as dominant random disturbances from the guideways. Appropriate mathematical modeling of the input process is presented in terms of spectral density function which is further modeled as the output of a second order linear filter under a white noise input for easy analysis. The combined filter-vehicle stochastic equations are solved numerically and the suspension bounce acceleration behavior for different system parameters is presented.]]></description>

      <title>SUSPENSION BOUNCE RESPONSE OF CANADIAN MAGLEV VEHICLE UNDER GUIDEWAY EXCITATIONS - 1. DETERMINISTIC ANALYSIS</title>
      <link>https://trid.trb.org/View/180912</link>
      <description><![CDATA[The dynamic bounce response of the Canadian designed high speed magnetically levitated vehicle is investigated when subjected to purely periodic excitations from the guideways. The equations of motion of the system are derived, on the basis of a realistic linear mathematical model, using d'Alembert's principle of force and moment analysis. Solutions for the system responses in the time and frequency domain are obtained using numerical techniques. Although the main emphasis of this study is focused on the bounce response of the vehicle body as a measure of the ride quality of the vehicle, the vehicle pitching response as well as the bounce responses of the levitation magnets are also given appropriate attention.]]></description>

      <title>AUTOMATED DESIGN FOR AUTOMOTIVE STRUCTURES</title>
      <link>https://trid.trb.org/View/181125</link>
      <description><![CDATA[The application of mathematical structural optimization methods to automotive structures is discussed.  The global structures are typically simultaneously frequency and stress constrained.  In addition, bending effects in the components cannot be ignored.  Therefore, it is necessary to develop a very general approach while still retaining computational efficiencies.  It has been found that approximation techniques coupled with mathematical programming allow the optimization of moderately realistic structures.  In addition, there is a class of problems which must be characterized in terms of their boundary shape.  This imposes a new set of difficulties primarily of insuring model integrity during the optimization.]]></description>

      <title>WHEEL AND BRAKE SHOE FIELD TESTS (1980)</title>
      <link>https://trid.trb.org/View/179550</link>
      <description><![CDATA[The results of tests that were conducted in service to verify information and gather new insight into the effects of various brake shoes as they influence the temperature of 914 mm freight car wheels are discussed. Tests were run with three types of brake shoes, cast iron, high phosphorus cast iron, and anchor composition with the car empty and loaded. Temperatures were measured at seven internal locations, using embedded thermocouples. A silicon pin diode which detects hot spots on the tread by infrared radiation was also used.]]></description>

      <title>APPLICATION OF THE FINITE ELEMENT METHOD IN THE STUDY OF SNAP RING GROOVES IN RAPID TRANSIT CAR WHEELS</title>
      <link>https://trid.trb.org/View/179551</link>
      <description><![CDATA[This paper discusses the finite element method techniques used in the study of stresses in rapid transit 771m car wheels. Particular attention is given to the elastic stresses near the circular groove under the front rim to accommodate a snap ring for wheel noise reduction. In-service wheel temperatures and experimental wheel mounting stresses are compared to theoretical predictions. Thermal and mechanical loads are discussed separately and in combination for their influence on elastic stresses in the groove area.]]></description>

      <link>https://trid.trb.org/View/179552</link>
      <description><![CDATA[The overlay of a tread brake system to the main disc brake system has shown a significant reduction in the amount of wheel tread damage and a corresponding increase in wheel life. The approach with regard to braking which has been taken to deal with these situations is described. Tests and evaluation on a dual brake system are described and comparative results are given.]]></description>

      <title>COMPARISON OF ENERGY-STORAGE DEVICES FOR USE IN FUTURE AUTOMOBILES</title>
      <link>https://trid.trb.org/View/179667</link>
      <description><![CDATA[A study was made to determine which energy-storage devices and their associated propulsion systems are likely to be capable of providing credible alternatives to current automotive propulsion systems between now and the year 2000. It was found that a complete spectrum of automotive performance levels can be achieved by energy storage automobiles during this time period. These range from automobiles with general-purpose performance equivalent to internal combustion engine performance to performance suitable for vehicles with specific missions. Large scale introduction of such vehicles can be constrained not only by the development of energy storage technology, but also by the availability of the required manufacturing capability and service infrastructure.]]></description>

      <title>INFLUENCE OF RESTORING TORQUE BETWEEN TRUCK AND CAR-BODY ON THE TRANSVERSAL STABILITY OF A RAILWAY-CAR AT SEVEN, SEVENTEEN AND NINE DEGREES OF FREEDOM</title>
      <link>https://trid.trb.org/View/174528</link>
      <description><![CDATA[The dynamic behavior of a high speed free truck or railway carriage running on an aligned track with optimal geometric conditions can be tabulated in full matrix A (7,7) or A (17,17). Apart from the classical connection the car-body truck connection includes hydraulic damping devices whose force-deplacement diagrams are similar to that of a frictio damping device. The characteristics of the restoring torque relative to the truck can be compared to a hysteresis cycle. For a reduction of the number of degrees of freedom, only a truck with a half carbody:A(9,9) was considered.]]></description>

      <title>SUSPENSION SYSTEM SYNTHESIS FOR MASS TRANSPORT VEHICLES WITH PRESCRIBED DYNAMICAL BEHAVIOR</title>
      <link>https://trid.trb.org/View/174529</link>
      <description><![CDATA[A synthesis procedure to produce redesign recommendations for the suspension of mass transport cars is presented. The objective of the study was to improve the performance of the suspension system under dynamic conditions, so as to yield resonant velocities outside the range of most frequent operation. It was found that only one of the two sections of the suspension need to be damped and the corresponding damping value was obtained via a Root Locus analysis.]]></description>

      <link>https://trid.trb.org/View/174358</link>
      <description><![CDATA[A small passenger car with LH sub 2 tank for the range of 400 km installed in the rear trunk, demonstrated the overall feasibility of hydrogen fueled cars by the attainment of a maximum power 20 to 30 percent higher than its gasoline engine counterpart and about twice as high than that of premixed engine without backfire or knocking and with a very low NOx emission level was achieved by the injection into the two-stroke engine of - 30 to - 50 C cold hydrogen gas pressurized by a LH sub 2 pump. Studies on the development of the LH sub 2 pump are emphasized in this paper.]]></description>
