摘　　要：应用多体动力学仿真软件Recurdyn研究悬架系统对无人平台的操纵稳定性的影响,选取某种6X6轮式无人平台双横臂独立悬架为研究对象,使用Recurdyn进行参数建模,再对悬架进行运动学仿真分析,选取筛选后的参数点作为优化变量,使用Recurdyn/AutoDesign模块,对定位参数进行优化设计,根据仿真结果对悬架结构进行优化,使前束角与侧倾角的振动幅度减小30%左右,以便拥有更好的运动性能,最终达到改善其操纵稳定性的目的。利用现有理论与仿真平台克服了传统悬架优化设计难,效率低等问题,减少大量的设计成本,经过适当改进可适用于其他类型悬架优化。Using Recurdyn,the multi-body dynamic software,to research the influence of suspension system on handling stability of unmanned platform.It took on 6x6 wheeled unmanned platform double-wishbone independent suspension as research subject,established it’s parametric model and carried out the kinematic simulation analysis in Recurdyn.Select the screened parameter point as optimization variables and optimize the positioning parameters through Recurdyn/Auto Design.Based on the simulation result,the suspension structure is optimized,made the toe angle and camber angle vibration amplitude reduced by 30 percent,enabling it to get a better performance.Ultimately achieve the objective of improving the handling stability.Using the existed theory and simulation platform overcome the problems of traditional suspension optimization design,reduced the design costs and low efficiency.Using the existed theory and simulation platform overcome the difficulties such as low efficiency and traditional suspension optimization design,etc.After appropriate improvement,it can be applied to other types of suspension optimization.
