      <title>CRASH TESTS OF SHARPLY CURVED LIGHT-POST GUIDERAIL</title>
      <link>https://trid.trb.org/View/170434</link>
      <description><![CDATA[Cables, W-beam, and box-beam guiderail on S 3x5.7 posts were crash tested on 50- and 100-ft radius curves. Head-on impacts on these sharply curved barriers produced much different results than standard angled impacts on tangent barriers. For the cable and W-beam barriers, deflections were much greater than for standard impacts, but decelerations remained low. For box-beam, deflections increased only slightly, but decelerations were greater.]]></description>

      <title>CABLE-STAYED GUIDEWAY. ANALYSES AND DYNAMIC MODEL TESTS</title>
      <link>https://trid.trb.org/View/23583</link>
      <description><![CDATA[This report presents the results of scale model tests and parametric structural analyses which were performed in support of a conceptual investigation of cable-stayed guideways for suspended vehicle systems (SVS). The SVS concept would use high speed ground transportation (HSGT) vehicles suspended from an overhead guideway and which could achieve large cabin bank angles for high speed turns. This cabin bank mechanism allows the SVS to maintain a high speed, even when the guideway is collocated with an existing freeway or railroad with relatively tight turn radii. The possibility of collocating the SVS guideway is further improved by the use of cable-stayed guideways with spans of 200 feet or greater. This report describes the static and dynamic tests of a 1:24 scale model of a 250-foot span cable stayed guideway which was designed for a conceptual SVS.]]></description>

      <title>DESIGN STUDY OF STEEL V-BELT CVT FOR ELECTRIC VEHICLES</title>
      <link>https://trid.trb.org/View/162353</link>
      <description><![CDATA[A continuously variable transmission (CVT) design layout was completed. The intended application was for coupling the flywheel to the driveline of a flywheel battery hybrid electric vehicle. The requirements were that the CVT accommodate flywheel speeds from 14,000 to 28,000 rpm and driveline speeds of 850 to 5000 rpm without slipping. Below 850 rpm a slipping clutch was used between the CVT and the driveline. The CVT was required to accommodate 330 ft-lb maximum torque and 100 hp maximum transient. The weighted average power was 22 hp, the maximum allowable full range shift time was 2 seconds and the required lift was 2600 hours. The resulting design utilized two steel V-belts in series to accommodate the required wide speed ratio. The size of the CVT, including the slipping clutch, was 20.6 inches long, 9.8 inches high and 13.8 inches wide. The estimated weight was 155 lb. An overall potential efficiency of 95 percent was projected for the average power condition.]]></description>

      <title>SAINT LAWRENCE RIVER ICE BOOM MODIFICATION STUDY</title>
      <link>https://trid.trb.org/View/144100</link>
      <description><![CDATA[The objective of this study was to prepare designs and specifications for improvements to existing ice booms in the international portion of the Saint Lawrence River to allow extended season navigation through 31 December of each year. The study involved the construction and operation of a distorted scale (horizontal scale 1:150, vertical scale 1:60) hydraulic model of the section of the river extending from Stillwells Point, New York downstream to Red Mills, New York. The design and construction of the model are described. The model was used to develop and test concepts for improving the booms to permit navigation while maintaining or improving the stability of the ice cover and the hydraulic integrity of the river. These tests involved model ship passages through consolidated and unconsolidated ice conditions with and without simulated high winds. Results from the model were used to design structural components and to assess the impact on levels and flows of the river and Lake Ontario due to ice passing downstream of the booms.]]></description>

      <title>ANALYSIS OF FLOATING BREAKWATER MOORING FORCES</title>
      <link>https://trid.trb.org/View/63600</link>
      <description><![CDATA[A method for analyzing floating-breakwater effectiveness and mooring forces is presented. The mooring-line analysis is based on static equations and is included as a restoring-force term in the equations of motion for the breakwater. Results of the theoretical analysis are compared with model experiments and data obtained in the field. The theory consistently under-predicts mooring forces indicating that further refinement of the analysis is required. Evidence of long-period oscillations in the mooring forces is also presented and discussed.]]></description>
