基于UG的双横臂独立悬架运动学分析系统
Kinematics Analysis System of Double-wishbone Independent Suspension Based on UG Software
摘要
Abstract
A construction method for kinematics analysis system of the double-wishbone independent suspension based on UG software was proposed. The corresponding software prototype system using this method was developed and the frame structure of the system had been given account. Using the fast parameterized design function module of the system, the structure and geometric parameters of the double-wishbone suspension mechanism's simulation models could be rapid and convenient edited. By calling the MSC ADAMS or RecurDyn solver, which is integrated in UG/Motion, the kinematics simulation and analysis function module of the system could get the simulation results. The simulation results could be inspected using the drawing function of Matlab, which is integrated in this function module. Taking the minimum variation of the front wheel alignment parameters, minimum lateral displacement of the tires as the optimal object, the optimization design function module of suspension' s the structural parameters was constructed based on genetic algorithm. The correctness and the validity of the system and its function modules were verified by a design example. The frame structure of the system had good scalability and had been used in the optimum design of McPherson suspension.关键词
