Simulation Research And Experimental Verification Of Pneumatic System Of Lighter Automatic Colour Matching Equipment

With the support of Shaodong Intelligent Manufacturing Technology Research Institute Limited,this paper takes the pneumatic system of automatic color matching equipment of lighter designed and developed independently as the research object.Aiming at the problems caused by poor stability of pneumatic system,such as poor grasping and positioning accuracy,high noise,no buffer and low efficiency of pneumatic control manipulator,the pneumatic system of automatic color matching equipment of lighter is imitated.True research,the main work is as follows:Firstly,the functional requirements of automatic color matching equipment of lighter are determined,and its pneumatic servo control system is designed.The flow equation,temperature and pressure equation and flow parameters of the pneumatic components are analyzed,which provides a basis for the selection of simulation parameters.Then,according to the physical model of the actual pneumatic components,the mathematical motion models of the two-position five-way servo commutation valve,pressure reducing valve and its cylinder circuit are established.The thermodynamic equation of each component chamber,the motion equation of the commutation valve and the flow equation are deduced.The key parameters affecting the performance of the whole pneumatic system are obtained,which is the foundation and system of the subsequent system simulation model.The analysis of system characteristics lays a theoretical foundation.Secondly,the pneumatic simulation model of automatic color matching equipment of lighter is established by using AMESim software,and the dynamic characteristics of two-position five-way servo valve,cylinder and pressure reducing valve in the system are analyzed.Aiming at the instability of the pneumatic system caused by the system jitter caused by the piston rebound due to the lack of buffer device,the method of adding a pressure reducing valve at the intake end and an air bag accumulator at the exhaust end is adopted to solve the problem.Through AMESim modeling and analysis,the most stable parameters of pressure relief valve in the pneumatic system of automatic color matching equipment of lighter are obtained,and the optimum pre-storage pressure and volume of air bag accumulator are determined.Thirdly,on the basis of the above theoretical analysis and simulation,an experimental platform of pneumatic servo control system is built.The experimental results verify the correctness of the theoretical model and simulation results,and also prove that the scheme can improve the accuracy and stability of the pneumatic control system of automatic color matching equipment of lighter.
