摘　　要：轻量化设计对整车的动力学表现、全寿命周期成本及节能环保的意义越来越明显。随着列车运行速度的提升,随着对于节能环保要求的不断提高,轻量化无疑是未来轨道交通装备的发展方向。然而,结构件的强度、刚度等特性与其材料消耗有很大正相关性。这意味着单纯通过减少材料实现减重,往往要牺牲结构强度和刚度等性能。文中借助仿生学理念,运用先进设计方法,面向增材制造生产工艺,通过等强度设计去除不必要的材料,实现制动器结构件轻量化设计。Along with higher operation speed,light-weight design acts as a more critical factor to improve dynamic performance,to reduce life cycle cost and to save energy for rolling-stocks.However,the strength and stiffness of parts are usually related to the quantity of materials,which means strength and stiffness may not meet the requirement just by simply reducing materials.This article illustrates a light weight design of a lever for braking unit by equal-strength design of the structure.Advanced design method and additive manufacture are utilized in the design.
