铲运机工作机构设计方法研究

根据矿用铲运机工作机构处于插入工况、运输工况、举升工况和卸载工况的特点，建立了其六连杆工作机构的优化设计数学模型，编制了优化程序，以ＷＪＤ１．５ｍ^３矿用铲运机工作机构为例进行优化设计计算，并对设计前后工作机构的应力场进行了有限元建模和分析。研究结果表明，充分利用现代设计方法可以有效解决机构干涉和铲运机各技术指标的满足问题，并缩短产品的设计和开发周期。

Study on the Design Method for the Working Mechanism of Scraper

According to the characteristics of the working mechanism of mining scraper in the working conditions of reclaiming, carrying, raising and dumping, the optimal model of the mechanism was established by using the modern design theory. An optimal software used for designing the mechanism was programmed. As an example, the working mechanism of WJD 1.5 m 3 scraper was calculated and designed. The stress field of the traditional mechanism and the designed mechanism were modeled and analyzed with the finite element method. It is well known that making full use of the modern design method can solve the problems such as interference of the mechanism and the satisfaction of the technological conditions. The period of design and development of the scraper can be shortened.
