摘要
由于具有优良的力学特性,气弹簧已广泛应用于汽车的开闭件中。文章基于商用车高架箱箱盖开闭过程中几何及力学关系建立了多目标优化模型。该模型以气弹簧固定点位置及最小伸展力作为设计变量,以影响操作舒适性的箱盖开启力、关闭力、开启临界角及影响成本的气弹簧行程的计算值与理想值的偏差率作为优化目标,通过matlab中多目标优化算法对原布置方案进行优化。结果表明,该模型可在降低最小伸展力及行程的前提下,即降低成本的情况下,满足相关人机工程要求,提升车辆系统人机舒适性。
Gas springs are widely used in opening and closing devices of automotive,due to their excellent mechanical properties.Based on the geometrical and mechanical relationship of the process of cover’s opening and closing,a multiobjective optimization model has been developed.The layout optimization has been reached through multi-objective optimization algorithm based on matlab,with positions of spring’s fixed points and minimum extension force as variables,and the deviation rate of operation forces,opening critical angle along with stroke from their ideal values as objectives.The results of the model match well with the demand of ergonomics,which can improve the comfort of operation.
