Abstract: The design process and checking method of forging front axle are introduced. The UG NX software to establish the front bridge three-dimensional mathematical model, UG finite element analysis module for stress simulation analysis, get the parts of the stress, strain cloud map, on this basis for lightweight design, weight loss of 11 kg, and the finite element structure strength check, trial-produced samples for bench test and vehicle road test. The results show that, the lightweight design scheme of the front axle meets the requirements of strength, stiffness safety and fatigue life, and realizes the lightweight optimization design of the 5T front axle structure of commercial vehicles. Through this method, forward design and analogy analysis can be carried out quickly, which provides ideas and methods for lightweight design of forging front axle products.
Key words: Front axle structure; Finite element analysis; Lightweight design
摘要: 介绍了锻造前轴的设计过程及校核方法。利用 UG NX 软件建立前桥三维数模,UG 有 限元分析模块进行受力仿真分析,得到零件的应力、应变云图,在此基础上进行轻量化设计, 减重 11 kg,并进行有限元结构强度校核,试制样件进行台架试验和整车道路试验,结果表明, 前轴轻量化设计方案满足强度、刚度安全性及疲劳寿命要求,实现了商用车 5T 前轴结构轻量 化优化设计。通过此方法可快速进行正向设计和类比分析,为锻造前轴产品轻量化设计提供 思路与方法。
