摘要: 悬架对于车辆的平顺性和操作稳定性至关重要。目前的悬架设计方法无法实现通用运动副(球副、转动副、移动副)解析的汽车悬架拓扑构型优化,且存在迭代结果构型不清晰、收敛速度低等问题。因此,提出一种多运动副解析的汽车悬架拓扑构型优化设计方法,实现悬架构型与尺寸的协同优化设计。首先对悬架设计空间进行离散并对离散节点采用“三弹簧”约束后通过离散节点之间的杆系来建立多弹簧杆件模型;其次,采用能量法建立悬架设计域离散模型的整体准静态平衡方程,求解车轮垂直跳动输入下模型的状态变量,并以功传递效率最大化为目标,车轮轮距、前束和外倾等运动学特性为约束,建立悬架构型拓扑优化模型,实现悬架构型与尺寸的优化设计;最后,提出构型识别算法来解决悬架构型不明确,收敛速度慢的问题。多个算例表明,提出的设计方法不仅能够实现严格空间下的悬架拓扑构型设计,同时还能实现多种运动副的新型悬架构型创新设计。

Abstract: Suspension is critical for vehicle ride comfort and operational stability. The current suspension design method cannot realize the topological configuration optimization of multi-joints(spherical, revolute and translational joints), and there are problems of unclear configuration and low convergence speed. Therefore, a topological design method of multi-joints parsing is proposed, the optimal design of topology and size is realized. Firstly, the suspension design space is discretized and the discrete nodes are constrained by the “three springs”. Then, the multi-spring rod model is established through the rod system between the discrete. Secondly, the quasi-static equilibrium equation is established to solve the state variable, with the goal of maximizing work transmittance efficiency and the kinematic characteristics such as wheel track, toe and camber as the constraints, the optimization model is established to realize the optimal design of topology and size. Finally, the identification algorithm is proposed to solve the problem of unclear configuration and low convergence speed. Many examples show that the proposed design method can not only realize the topology design in strict space, but also realize the innovative design of the new suspension configuration of multi-joints.
