1、 安徽工程大学本科 毕业设计(论文) 专 业: 车辆工程 题 目: 直推式自卸汽车举升机构 的建模与仿真 作 者 姓 名: 导师及职称: 导师所在单位: 安徽工程大学 2013 年 6 月 安徽工程大学毕业设计 (论文 ) I 直推式自卸 汽 车举升机构的建模与仿真 摘 要 本次设计是以直推式自卸车为 设计 平台,对其举升机构的建模与仿真,那么首先我要对其举升机构进行建模,采用 UG 软件进行整车的车架与车厢及其举升机构的建模,在建模之前对已经选定的汽车参数进行其余一系列的参数设计,包括 举升机构的与 液 压机构设计,最终设计出与参数匹配的模型,对其模型进行修改,在建立模型以后,在运用 UG
2、的运动仿真项目得到模型的仿真文件。 同时得到直推式前置式举升机构具有省力的效果,不利的是其行程过长。对于直推式前置式自卸车主要应用在重型货车上面巨多,因为重型载货汽车,承载的质量较大,在举升时必须考虑到省力情况,相信会找到自卸车举升机构的一个平衡点,使得省力同时行程也比较短。 关键词 :自卸车 ;举升机构 ;液压机构 UG;建模 ;UG 仿真 吴兵兵:直推式自卸汽车举升机构的建模与仿真 II Modeling and Simulation of Straight Push Lifting Mechanism of Dump Truck ABSTRACT This design is based
3、 on direct push dump truck platform, the modeling and simulation of the lifting mechanism, so first of all I want for the lifting mechanism modeling, using UG software to the vehicle frame and the carriage and the modeling of the lifting mechanism of already selected in the car before modeling param
4、eters for the rest of the series of design parameters, including hydraulic press design, final design and parameter matching model, the model is modified, after the model, the use of UG simulation project get movement model of the simulation file. At the same time get straight push superposed liftin
5、g mechanism has the energy saving effect, disadvantage is the adults too long. For straight push superposed on the dump truck is mainly used in heavy duty truck giant, because of the heavy duty truck, bearing quality is bigger, and effort must be taken into account when lifting, believe that will find a balance point of lifting mechanism of tipper, makes the energy at the same time also shorter.
