In order to reduce the side-slipping of the tyre and increase service life and enhances the turning stability of the vehicles, the steering trapezium organization optimized design is extremely important in the vehicles research and development. The fast accurate design steering trapezium organization becomes one of key technologies in vehicles design. This article first establishes about the vehicles the wheel ideal corner relations, obtains the constraint condition which in the steering trapezium organization optimization design. Has established the telehandler dummy specimen model based on ADAMS software. Input telehandler entity parameter, Has realized steering trapezium organization accurate optimized design fast. The model mainly contains the parameter preparation, the design coordinate foundation, various components connection form as well as each component model foundation, finally realizes the machine model output. Simulation confirmation, to the wheel actual corner and the theory corner has carried on the fitting analysis and the error analysis, has proven the optimized design structure accuracy and the model establishment accuracy. This method may realize the different vehicle type steering trapezium organization fast optimized design.
