Ct36-110 Spring Actuator Disk-shaped Cam Optimization Design And Cnc Machining,

This paper summarizes the domestic and overseas study status and developing direction of cam. On basis of the problem that the idler wheel which is the driven part of the cam machine in CT36-110 spring operating mechanism is destroyed easily, the author get much fact material through inner research, and presents a optimal design imagine of disc cam. Through enough compare and argumentation, this paper presents the optimal design model of the disc cam.Using large-scale finite element software ANSYS as analyzing tool, this paper introduces the basical principles of finite element method which can be used for optimal design, describes the principles and methods of design optimization for disc cam, establishes the finite element models of disc cam, calculates the static strength, and then creates the analytic documents, and makes optimal design of the disc cam with the goal function of minimum contact stress. The author compared the mechanical capability of the disc cam before optimal design and after it, analyzes the feasibility of the optimization results.Create the 3D-solid model of disc cam in the quite excellent domestic CAM software—CAXA manufacturing engineer 2004, and make contrail simulated cutting of tool coarse machining and finish machining on terminal drawing, and create NC code on the computer at the same time. Using this method reduce much program time, avoid man-made error in the. process of program by hand, improve the efficiency, reduce the losing and wasting.The models and methods of optimization design for disc cam which in CT36-110 spring operating mechanism that the paper has put forward has some theory significance and applicable value for spread and apply the CAD/CAE/CAM technique in high voltage switch industry.
