本文介绍了HY-682型大客车车身骨架与底架静强度电测试验。大客车车身是一复杂的空间静不定薄壁杆系结构,加上汽车的使用工况多变,载荷又是随机的,试图用解析法来计算其车身强度和刚度是十分困难的。目前还难以用来作为设计的可靠依据,不得不有赖于试验来加以印证。本文通过试验,找出了HY-682型大客车车身骨架与底架应力较大的分布区域,从而为汽车车身结构的研究和设计提供了参改资料。
This article introduces HY-682 bus body frame and chassis static strength test. Bus body is a complex space static indeterminate thin-walled structure, coupled with the changing use of the car changing conditions, the load is random, trying to use analytical method to calculate the body strength and stiffness is very difficult. At present, it is hard to use as a reliable basis for design and has to depend on the test to prove it. Through the test, this paper finds out the distribution area of HY-682 bus body frame and chassis stress so as to provide reference information for the research and design of automobile body structure.
