連桿機(jī)構(gòu)運(yùn)動(dòng)分析 上海申弘閥門有限公司 ABSTRACT: In this paper, it had predominantly discussed swing-type feeding mechanism for design of the model by Math CAD software, and takes it as the example typically; it also focused on contemporary international research on the swing type feeding mechanism, contributing original views on the scope of its analytical procedure. By the kinetics standpoint it had built up a position expression type of the link mechanism, in addition, explained clearly the automatic computation its data of movement analysis and the result process in graph, finally, there alization method about the link mechanism movement simulation had been introduced. KEY WORDS: link mechanism; math CAD; slipper block; movement analysis; simulation. I. INTRODUCTION Over the past few decades, engineering schools have placed a high priority on incorporating computer technology into the engineering curriculum and this has been no incidental achievement Specially, this article take swings feeds in the analysis of mechanism as an example, introduced using the Math CAD software to carry on the movement analysis and the simulation method to analyze the swing-type feeding mechanism, and explain the theories analytical method of these type of engineering problem thereby. II. MOVEMENT ANALYSIS OF LINK MECHANISM This swing-type feeding in the mechanism, the anti clock wise rate of angular motion of original moving parts is:ω1= 40rad/s ，and its structure with various components size as shown in Fig.1.In Fig.1 above the swing-type feeding in the mechanisms consist of the crank original moving parts 1 i.e. _grade pole group and the _ grade pole group. In which, component2 and component 3 is belong to the RRR type of _ grade pole group; but the component 4 and component 5 is belong to the RRP type of _ grade pole group. Using the tool platform of the MathCAD software to analyze the original moving parts and The move position relationship of _ grade pole group separay; and establishes its various hinge points the position relational expression, according to the above and solution mechanism movement analysis result III. LINK MECHANISM MOVEMENT SIMULATION The mechanism simulation is changed by the quantity off rame variable into to realize In the MathCAD soft ware environment. The frame is an internal variable in Math CAD, what it represents is the static picture frame serial number, and according to convention from zero start. Through the computation production continual serial number picture frame broadcast, it may produce the mechanism animation simulation results. IV. CONCLUSIONS Simulation by MathCAD, our new heuristic for extreme programming, is the solution to all of these obstacles about dynamic analysis in swing-type feeding mechanism. By incorporating and combining the calculations, graphs, text and images in the paper above, the MathCAD enables us knowledge capture、movement design and aid management of engineering analysis projects, and the dynamic simulate or demonstrates high integrity of accuracy while compressing computational time. Moreover, the frame animation in simulating for step loads, changing input time varying quantity, stability, and steady state transient analysis for expediting design completion, and optimizing on the dimensions or size of cost efficiency. In fact, the main contribution of our work is that we introduced a system for swing-type feeding mechanism with MathCAD software. The investigation of dynamic analysis in animation is more theoretical than ever, and our approach helps our Research Team to do just that. Although there were a few disadvantages associated with the others, in the opinion of us those disadvantages were more than offset by the numerous advantages provided by MathCAD. The MathCAD is the industry standard technical calculation tool for engineer’s world wide; it provides powerful combination of rapid solution prototyping and experimentation in analysis of mechanism.
