摘要: 本文以开沟铺管机独立行走机构为主要研究对象，针对传统开沟铺管设备工作环境适应性差，工作环境要求高等问题，对传统开沟铺管设备行走机构的结构和其组成部件进行优化设计并进行强度校核。首先，对开沟铺管机的行走系统进行分析得到其相应的改进方案；其次，利用计算机辅助设计软件对现有的开沟铺管机行走机构进行建模并得到其相应的CAD模型，利用优化设计软件ANSYS等对该CAD模型进行优化，以满足行走机构的使用环境要求；最后，通过Pro/E对优化后的行走机构进行重新的建模、装配、模拟仿真，利用ANSYS对优化后的行走机构的结构进行有限元分析，采用有限元法对行走机构的主要部件进行全面静力分析，为开沟铺管机行走机构的结构优化设计提供充分的理论基础。

Abstract: In this paper, the main research object is the independent traveling mechanism of open groove laying machine. High issues are required, the structure of the traditional trenching equipment travelling mechanism and its components are optimally designed and strength checked. First of all, the corresponding improvement scheme is obtained by analyzing the traveling system of the ditching machine; secondly, computer aided design software is used to model and obtain corresponding CAD models for the existing open groove pipelining mechanism. A CAD model is obtained and the CAD model is optimized by using the optimization design software ANSYS to meet the environmental requirements of walking institutions. Finally, through Pro/E, the optimized traveling mechanism is re-modeled, assembled and simulated. ANSYS was used to analyze the structure of the optimized traveling mechanism. The main components of traveling mechanism are analyzed by the finite element method. It provides a sufficient theoretical foundation for the structure optimization design of the running mechanism of the groove laying machine.
