Bogie Production Simulation Based On Professional Software

With the rapid growth of China's national economy and the continuous development of science and technology,high-speed EMU has been widely used in railway transportation.Bogie is one of the most important components of high-speed EMU,which has the functions of supporting the body,steering,braking and so on.Bogie has parts components,complex structure and complex production process.It is easy to cause the unreasonable allocation of production resources and the bottleneck is not easy to identify in the production process.The traditional production process planning method can not solve the problems of high-speed EMU bogie in production process.The development of simulation technology of production system is of great help to the design and optimization of the bogie production process,which provides an effective way to solve the problem of the process planning and optimization.First of all,aiming at the problems existing in production process of bogie,this article puts forward the idea of optimizing production process of bogie by means of production system simulation.And combined with the development of simulation technology at home and abroad,the article puts forward the research direction of the establishment of bogie production system by means of professional visual simulation software CraftManage.Secondly,it expounds the concept and classification of system simulation,introduces discrete system simulation,studies the simulation contents and influencing factors of discrete production system,and analyzes the difficulties existing in simulation of mixed flow discrete production system,and integrates the existing production system simulation evaluation methods.Then,taking the bogie manufacturing center of a rail factory as the research object,with the help of 3ds Max modeling software,the production system 3D model of the bogie is established in the professional simulation software CraftManage,including the establishment of bogie workshop,component resource library and equipment model.Based on the production process of the bogie of CRH3 EMU,the simulation of the production process of the bogie is carried out with the established simulation model.Finally,the method of solving bottleneck process of bogie production line is explained by the theory of optimized production technology and the theory of constraints.Combined with the simulation data,the bottleneck of the production line is analyzed from the aspects of production capacity,equipment utilization and WIP.Aiming at the problems,a reasonable optimization scheme is put forward,so as to achieve the goal of eliminating the bottleneck,optimizing the process and improving the production capacity.
