Research on Forming Process and Key Technologies of Arc Rods of Bus Body

Abstract

客车对发展国民经济和促进人民生活水平提高发挥着重要作用。客车是现代社会中的主要交通工具之一。客车车身是其它部件的载体,承载着车身的负荷,即要保证足够的强度,还起到密封、造型、装饰等作用。因此,客车车身的质量对客车总体质量起到关键作用。车身骨架是保证客车车身强度和刚度而构成的空间框架结构,骨架由许多不同空间弧度的杆件合装而成。弧杆件作为客车车身骨架的主要零件,对客车车身制造质量非常重要。在装配过程弧杆件质量直接影响其骨架装配质量,因此弧杆件制造质量就成为重中之重的任务。同时弧杆件在成形过程质量难以控制,主要原因杆类零件在成形过程受到回弹因素、模具、材料和塑性变形等因素的影响。因此,在国际市场竞争...Bus plays an important role in the development of national economy and the improvement of living standards. Bus already made one of vehicle in the modern society. Bus body is the carrier of the other parts. It load the whole body weight, that is, to ensure sufficient strength, also play a role of seal, shape and decoration. Therefore, the quality of the bus body plays a key role in overall quality...学位:工程硕士院系专业:物理与机电工程学院机电工程系_仪器仪表工程学号:X200618201
