1、摘 要 I 基于 Pro/E 的装载机工作装置的实体建模及运动仿真 摘 要： 装载机是一种应用广泛的工程机械。有其广泛的空间，但由于装载机传统开发模式存在的开发周期长、过程繁杂、 开发成本高、性能测试困难等问题，本文将仿真技术引入装载机开发领域，完成以下工作： 1 介绍了装载机的发展历史及前景，装载机的种类，介绍了仿真技术产生的背景、在国内的发展状况以及仿真 技术的实际意义。 2 对液压缸作出了合理的选择。 3 简述了 Pro/E 软件在工程设计中的应用，利用 Pro/E 构建装载机的三维实体模型，并对其进行装配，在 Pro/E 环境下进行了装配干涉检验。 4 在 Pro/ENIEER MEC

2、HANISM 环境下进行运动仿真,得出装载机工作的性能曲线。 关键字：装载机 工作装置 液压缸 仿真技术 三维建模 Abstract： Loader is a kind of engineer machine that is widely applied in engineer project, which has wildely space, Aim to the problems that exist in traditional research way of loader, for example the research cycle is long, the cost is long

3、, the cost is high and the performance test is complex etc, this paper leads virtual prototype technology into research of loader. The following research works are completed: 1. The development foreground, the category and loaders history is introduced, also the background of simulation technology c

4、ome into being, developing status in local and the significance of virtual prototype technology is introduced. 2. To brief introduce the Pro/E software which application in the field of engineering, the 3D modeling is used by Pro/E software, which is built and interferential test of assembly in Pro/E environment is completed. 3. The simulated motion in Pro/E environment is completed, and the capability curve is reached. 4. A rational choice for the hydraulic actuating cylinder. Keywords: L
