Dynamics Simulation Research on Rigid-Elastic Coupling System of Car Suspension 2000-01-1622

In modern car, to reduce car deadweight, lightweight technology is widely used; and to improve comfortable and handling performance, many rubber bushings installed between car body and suspension. These parts have difference characteristics during car running at high speed comparing these at static state.
Accounting the suspension performance has a decisive influence on a car, the flexible parts should be taken into account in the suspension/steering system simulation model. As a deviant phenomenon, the steering wheel shimmy affects the suspension's dynamic characteristics greatly. To analysis this abnormal running state, the front wheel bounce tracks were figured out by using different front suspension model. The flexible parts installed in suspension are idealized respectively as rigid poles, flexible beams or forces, hence, the rigid suspension analytical model and the rigid-elastic suspension model analytical were built respectively.
In this paper, suspension dynamic performance and flexible parts' influence were suggested to analyze, and the sensitivity analyses are suggested to reduce the steering wheel high frequency shimmy. The ADAMS” program is used to simulate the test condition in sensitivity analysis and to predict the vibration of the front wheels.
