大方量混凝土搅拌车为了降低整车高度,从而在设计上取消了副车架,这就对底盘的承载系统提出了更高的要求。笔者结合自己开发大方量混凝土搅拌车底盘的经验,谈下车架的设计及CAE分析验证。1前言大方量混凝土搅拌车因受国家法规限值,取消副车架以降低整车高度是一个有效的手段,这就对底盘的承载系统提出了更高的要求。而底盘车架不仅是车辆承载的基体和零部件连接的载体,它还承受来自车辆内外的各种
In order to reduce the height of the whole vehicle, the massive concrete mixer canceled the sub-frame in the design, which puts higher requirements on the bearing system of the chassis. The author combines his own experience to develop generous amount of concrete mixer chassis, talk about the frame design and CAE analysis and verification. 1 Introduction Generous concrete mixer truck due to national laws and regulations limit, cancel the subframe to reduce the height of the vehicle is an effective means, which on the chassis carrying system put forward higher requirements. The chassis frame is not only a vehicle-mounted substrate and components connected to the carrier, it also from inside and outside the vehicle
