摘　　要：为解决履带车辆变型设计中车体姿态调整问题,提出了一种基于虚拟样机技术和参数优化技术的新方法。建立变型履带车辆的多体动力学模型并进行了实验验证;选择平衡肘预安装角作为设计变量,以车体距地高为约束条件,车体姿态参数为目标函数进行了优化;对优化后的车辆车体姿态及扭杆弹簧最大剪应力进行了校核,证明了本文提出的车体姿态调整方法的可行性。A novel method based on virtual prototype and parametric optimum techniques is proposed to solve the problem of hull attitude adjustment in variant design of tracked vehicles.Firstly,a multi-body dynamic model of the variant vehicle is established and validated experimentally.Then,the initiative mounting angles of road arms can be chosen as design variables,the distance between the ground and the bottom of hull can be defined as a restricted condition,and the hull attitude can be taken as the object function of parametric optimization.Finally,the hull attitude of the optimized vehicle and the maximum shearing strength of torsion bar spring are checked,the feasibility of adjusting attitude method proposed in this paper is verified.
