ARTICULATED VEHICLE DYNAMIC ANALYSES USING EQUIVALENT LINEARIZATION TECHNIQUE

The equivalent linearization technique is presented as an analytical tool for studying the dynamic response of the nonlinear articulated vehicle system to random road excitations. The technique, which offers a compromise between the accuracy of nonlinear digital simulation and the efficient computation techniques of linear analysis, is an efficient method for parametric studies and for understanding many tractor-semitrailer dynamic problems. The technique can be used as a design tool and as an analytical aid for interpreting test results. Analytical results indicate that dry frictional forces should be considered in articulated vehicle analysis because of their significant influence on ride quality. The inclusion of the possibility of separation at the tire-road interface is of secondary importance.
