基于PS O的直线电机式混合悬架参数优化
Parameter Optimization of Hybrid Suspension with Linear Motor Based on PSO
摘要
Abstract
A kind of mixed suspension is proposed in this paper to recovery suspension vibration energy.It consists of linear motor and damper in parallel.In order to coordinate the dynamic performance and energy recovery performance of suspension,firstly,the dynamic model of mixed suspension was established.The damper’s impact on mixed suspension was studied,and the damper-coefficient was set as optimization parameters.Then the comfort,safety and energy recovery performance of mixed suspension was set as optimization goal.Multi-objective optimization function was set.And 1/4 suspension model was set as the object of study.Multi-objective particle swarm optimization (PSO)was used to seek global optimal solutions.The energy recovery performance was promoted,and the dynamic performance was considered after optimization.It indicated that the algorithm has better effect in the mixed suspension parameters optimization.Finally,1/4 bench test was carried out,and it demonstrated the effectiveness of the optimization results.The studycan provide reference for the research of energy-saving suspension.关键词
