The Optimization Study of the Front Suspension Structure Parameters for the Mine Truck Based on Adams/car

Abstract

The suspension performance is heavily determined by the suspension structure parameters. This paper researches the geometric relations between the structure parameters of double wishbone front suspension and alignment parameters of steering wheel, then establishes a double wishbone suspension steering system dynamics model using ADAMS/car, finally simulates and optimizes the main hard points of the front suspension with the wheel alignment parameters as optimization objective. The optimized steering wheel alignment parameters basically meet the design requirements, and the calculated results have been applied to the real truck, and achieved good results.
