| Abstract: | A whole FE-model of steering system was built including steering joints,steering column and steering system, and exerted the frequency spectrum of acceleration obtained by test to steering joint to simulate frequency response functions, then optimized the results based on the thickness or structures of major plates,at last tested and verified the optimization results.The example indicates that the analysis method can analyze and solve the problem of steering wheel shake successfully during the vehicle high-speed driving.Thus, the method provides an significant idea of vehicle's research and development, and shortens vehicle's development period greatly. |
