Simulation Design and Experimental Analysis of Commercial Vehicle Cab Suspensions

A dynamics simulation model was established and testified by bench test researches for the development of a cab suspension and based on which the vibration isolation was optimized. A finite element model was also built and validated using the boundary conditions extracted from the dynamics model. Several limiting conditions were analyzed, which gave back necessary informations for modifying the structures of cab suspensions. The fatigue characteristics of the cab suspension was also tested by the fatigue tester. The results show that the difficulties encountered in researches and developments of cab suspensions may be solved efficiently by the method of simulation design and experimental analyses.
