【摘要】：小型装载机是一种国际通用的小型工程机械产品,是全球工程机械市场上非常受青睐的产品之一,特别是在中国等发展中国家和地区,数量众多。装载机驱动桥是小型装载机的重要部件,是小型装载机整机性能的重要组成部分。小型装载机整机体型较小、结构紧凑,所以装载机驱动桥结构也较为复杂且紧凑,整机的所有零部件如发动机、驾驶室、动臂、油缸、覆盖件等都是以驱动桥作为承重基础的。所以,小型装载机驱动桥的结构是否合理,强度是否满足作业工况,是一个很有价值的研究课题。本课题以徐工集团徐州徐工特种工程机械有限公司LW18系列小型装载机前驱动桥ZLQ20A为研究对象,利用国际著名的大型通用有限元分析软件ANSYS,根据小型装载机驱动桥的实际作业工况,建立有限元分析模型,确定各典型工况下驱动桥的载荷并进行分析,掌握驱动桥各部分的位移和应力分布规律,整体研究小型装载机驱动桥的强度和可靠性,通过对小型装载机驱动桥的有限元分析,可以为公司以后同类型产品结构件设计参数的确定、提高系统动静态性能、降低成本,提供科学的依据和实践的基础,为以后新产品的开发和设计提供理论基础。
[Abstract]:Small loader is one of the most popular products in the global construction machinery market, especially in China and other developing countries and regions. Loader drive axle is an important part of small loader, which is an important part of the performance of small loader. Small loader has a small size and compact structure. So the structure of the loader drive axle is also more complex and compact, all the parts of the whole machine, such as engine, cab, arm, cylinder, cover and so on, are based on the drive axle. It is a valuable research topic whether the structure of the drive axle of small loader is reasonable and whether the strength meets the working condition. The research object of this subject is ZLQ20A of LW18 series small loader front drive axle of Xuzhou Xugong Special Construction Machinery Co., Ltd. The finite element analysis model is established according to the actual working condition of the drive axle of a small loader by using the internationally famous universal finite element analysis software ANSYS. The load of drive axle under typical working conditions is determined and analyzed, the displacement and stress distribution law of each part of drive axle is grasped, and the strength and reliability of drive axle of small loader are studied as a whole. Through the finite element analysis of the drive axle of the small loader, it can provide scientific basis and practical basis for the determination of design parameters of the same type of product structure parts in the future, to improve the dynamic and static performance of the system, to reduce the cost and to provide the scientific basis and practical basis. For the future development and design of new products to provide a theoretical basis.
