Simulate Design and Experimental Analysis of Commercial Vehicle Cab Suspension

Proper simulation design and experimental analysis is an efficient and low-costing way in researching and developing commercial vehicle cab suspension. A dynamic simulation model was established and testified by bench test for the development of one cab suspension, and based on which the performance of vibration isolation was optimized. A finite element model was also built and validated using the boundary condition extracted from the dynamic model. Several limiting conditions were analyzed which giving back necessary information in modifying the structure of the cab suspension. The fatigue characteristics of the cab suspension were also tested by the fatigue tester. The results show that the difficulties encountered in researching and developing the cab suspension can be efficiently solved by the method of simulation design and experimental analysis.
