Precise Start Stop Control Method for Rolling Piston Compressor Rotor
摘要
Abstract
Aiming at the problems of uneven temperature distribution,stress concentration and vibra-tion intensification in rolling piston compressors,an accurate control method based on rotor heat transfer e-quation and analysis of influencing factors is proposed.The rated conditions for the rotor's operation are set,and the heat transfer equation with the temperature distribution in the cylinder and the rotor on the same scale line is obtained,and the heat transfer boundary conditions are given.The linear analysis algo-rithm is used to calculate the numerical value of the thermal stress field of the rotor,and the calculated thermal stress field data is used to calculate the continuous operating load in combination with the mechan-ical characteristics of the compressor rotor,and the stable working conditions of the inner cylinder pressure are set based on the load,which is used as the basis for judging the start-stop control.Based on the de-tailed model of the working structure of the compressor rotor,the differential equation of the rotor vibra-tion is calculated,and the pressure change is converted into damping force to obtain the instantaneous exci-tation response amplitude of the start-stop.Combined with the judgment basis of the start-stop control,the best control factor is solved through the functional equation,so as to find the best control factor.Com-bined with fuzzy logic and sliding mode control,to minimize the vibration amplitude and improve the accu-racy and stability of the start-stop control.The experimental results show that the proposed method re-duces the amplitude fluctuation,effectively inhibits the vibration of the compressor rotor,avoids the load peak,and stabilizes the overall direction of the compressor load.关键词
