基于比赛工况下的新型全地形巴哈赛车悬架设计

Suspension design based on competition conditions

本文介绍了一款基于恶劣的越野场地下的悬架设计基本思路与流程。根据设计高通过性的车辆的需求,结合整车设计要求,初步确定悬架参数。选择悬架基本类型,进行Adams运动仿真,满足设定性能参数,确定悬架硬点。建立悬架零部件的概念模型,Adams运动仿真检查悬架运动间隙检查。根据悬架概念设计结构,建立Adams弹性运动学模型,并设定目标,调整各铰接点衬套刚度来满足设计目标,确定各铰接点的衬套。加载工况,分解各零部件受力、对零部件进行有限元受力分析,对零部件结构进行优化,根据悬架设定目标,计算稳定杆刚度和减振器阻尼,确定弹簧、稳定杆和减振器的设计参数。样车制造,进行悬架主客观评价并调校。

This article introduces the basic idea and process of a suspension design based on the harsh off-road field underground.According to the requirement of the vehicle with high throughput and the design requirement of the whole vehicle,the suspension parameters are preliminarily determined.Select the basic type of suspension,carry out Adams motion simulation,meet the set performance parameters,determine the hard point of suspension.The conceptual model of suspension components is established,and the motion clearance of suspension is checked by Adams motion simulation.According to the suspension conceptual design structure,the Adams elastic kinematics model is established,and the target is set.The stiffness of each hinge bushing is adjusted to meet the design target,and the bushing of each hinge point is determined.Loading conditions,decompose the force of each component,carry out finite element analysis of the components,optimize the structure of the components,calculate the stiffness of the stabilizing rod and the damper according to the suspension setting target,and determine the design parameters of the spring,the stabilizing rod and the damper.Sample car manufacturing,subjective and objective evaluation and adjustment of suspension.
