Study On Dynamic Characteristics Of The Feed Servo Drive System Of Forming Grinding Machine

Numerically controlled machine tools are developing in the direction of high speed,high precision and high efficiency. However, feed drive mechanism is importantcomponent part of machine tools, the dynamic characteristics of which directly affectthe machining quality and efficiency, so the demand of dynamic performance of feeddrive system of is higher and higher. In the High Speed Machining (HSM) technology,Numerically controlled machine tool feed drive system should have high speed and highacceleration. The dynamic characteristics of feed drive components not only directlyaffects the working performance and machining precision machine tools, but also has agreat influence to servo performance of feed servo drive. So dynamics dynamiccharacteristics of the feed driving mechanism must be researched in-depth. Numericallycontrolled forming grinding machine has the characteristics such as high precision, highresponse. The stability, responsiveness, etc of the feed servo drive system will affect thetooth profile of workpiece and the surface quality. Based on the forming of geargrinding machine feed servo system, the dynamic behavior characteristics are studiedin-depth using both the finite element analysis and the virtual prototype.According to studying the research status of forming grinding machine, thedevelopment status of the feed drive system development status and the mechanicaldynamics simulation, this article establish the multi-body dynamics simulation model ofthe feed drive mechanism based on the multi-body system dynamics theory. theestablishment of. The feed drive system dynamics model of forming grinding machinebed is established combined with Solidworks and ADAMS dynamic analysis tools.After setting the corresponding operating parameters of the machine, a large number ofsimulation analysis was gave to obtain the dynamic characteristics of the machineparameters.The coupled theory is introduced in the simulation analysis, the screw flexibleprocessing, set up virtual prototype model of the coupled feed drive system, in order toget closer to the real simulation results. The ball screw modal was analyzed in ANSYSsoftware to get the modal neutral file because of the vibration produced by ball screwdeformation. Combining with ADAMS to established the feed drive coupled model,simulation analysis was carried out on the model.Studies have shown that the elasticdeformation of the flexible body can cause the feed drive system "crawl" phenomenonwhich provide the research methods to improve the correctness of the simulationresults.The object of the thesis is profile grinding machines feed servo drive system. Itbuilt the machine’s electromechanical integrated simulation platform combination withC++, MATLAB/Simulink and ADAMS. It has the dynamics of the system inMATLAB driven simulation by changing the control strategy. The study showed that the greater the acceleration, the greater the impact on the machine tool. The platformcan verify the kinetic behavior on the different control strategies of machines operating.This article rigid-flexible coupling co-simulation technology is applied to the gearform grinding machine. Ii provides a solution and verification platform for the DynamicAnalysis of forming grinding machine feed drive system.
