摘要
针对悬挂结构及参数设计不合理导致的刚度曲线不理想、车辆姿态不一、调节困难等问题,在分析车辆电控空气悬挂特性指标、影响因素、约束条件基础上,提出了满足设计要求的电控空气悬挂特性优化设计规则与评价方法。建立多目标的悬挂结构优化目标模型,并对其结构及参数进行优化设计。研究结果表明:基于多目标电控空气悬挂结构优化目标模型、优化规则与评价方法,体现了前期悬挂设计与后期实车行驶的多方面要求;结构优化规则与评价方法科学、可行,适用于摆动缸与固定缸式油气悬挂的结构优化设计与评价。
For non-ideal stiffness curve,different attitudes or difficult adjustment of a tracked vehicle,which are resulted from improperly designed structure and parameters,a multi-objective target model for optimization structure of electronically controlled air suspension system( ECASS) is proposed based on the analysis of the characteristics indexes of ECASS as well as influence factors and constraints. The structure and parameters are optimized reasonably. The optimization design method and evaluation method are proposed. Research shows that both multi-objective optimization target model and evaluation method reflect the various requirements for whether designing in early or field running in later. The proposed method is suitable for optimizing and evaluating the hydro-pneumatic suspension with fixed cylinder or swing cylinder.
