摘要
Abstract
To improve the vibration hazard caused by small volume and high pressure in small reciprocating oil free air compressor,and improve safety performance,a study on the dynamic balance of a small reciprocating oil free air compressor was conducted.The moment of inertia required to calculate the balance of inertia force and moment was analyzed through the principle of mechanical motion and thermodynamic theory.And a counter mass block was designed according to the required moment of inertia and the space limitation of the air compressor.Subsequently,the finite element model of air compressor maneuvering balance was established,and the kinematics and dynamics simulation were carried out,and the total inertial force of the air compressor before and after balance and the vibration force of the crankshaft were compared.Finally,the vibration and noise test was carried out and compared with the simulation results.The results show that after balance,the total inertial force and crankshaft vibration force of the air compressor are significantly reduced,the vibration force at the fundamental frequency is also correspondingly reduced,and the vibration noise measured by the test is reduced by 17.88%,which verifies the rationality of the optimal design method of the mass block.Therefore,by adopting this method,the vibration of the air compressor is effectively improved,and it provides reference for the balance analysis of the air compressor.关键词
