轮式装载机的设计及运动仿真
摘要
装载机是工程机械的重要机种之一,在工程建设和土木建设中有着广泛应用,其工作装置设计为装载机设计中的重中之重,在装载机的整机性能中起决定性的作用。传统的分析方法和设计方法已经无法适应现今装载机的快速发展和行业间的激烈竞争,装载机及设备已是集机、电、液一体化;信息、激光等高新技术以及审美艺术于一身的现代机电产品,并且正在向着远距离控制、自动化和智能化等方向发展。
正基于此,本课题运用CAD三维软件(Pro/E)对装载机进行设计和研究。主要的工作如下:
1、在三维软件Pro/E中对装载机各个部件进行建模
2、在Pro/E中将建模好的部件装配成一个完整的装载机模型;
3、对装载机的工作装置进行运动仿真;
4、对装载机工作装置运用ANSYS软件进行有限元分析,对设计好的工作装置进行动态分析检查有无干涉,分析零件在计算载荷作用下的变形及应力分布,结合设计结果以判断零件设计是否合理。

Losder is one of the most important types of the construction machinery and is also been widely applied in engineerning construction and civil construction. The design of losder’s working device is the most important part in the design of a loader and plays a critical role in the function of the shovel loader. However, traditional analysis and design method fail to keep in pace with the rapid development of current loader as well as the petition of the field. Loader and its equipment are modem machinery bines machinery, electronics and laser as well as aesthetic art. The design theory and method of the engineering machine is on its way to remote control, automation and intelligentization.
Basing on this, this subject use the three-dimensional software of CAD(Pro/E) to design and research on the loader. Main tasks are as follows:
1. The modeling of the various parts of loader are structured.
2. Assembled in the three-dimensional of Pro/E.
3. The motion simulation of the loader working device.
4. The loader working device will be analysis by ANSYS in the dynamic. Analyze dynamically pleted working device to check for the interference. And analyze ANSYS finite element structure respectively according to different situations. Find out the deformation and stress distribution of ponents with load and then judge whether ponents are suitable on basis of the design
