高压星型空压机振动分析与虚拟样机仿真

摘要

The inertia force and inertia moment of high pressure Star-type air compressor were studied, and a method to balance the star-type air compressor was proposed. Kinematics and dynamics simulation were obtained through virtual prototype simulation of star-type air compressor by ADAMS software, and the change in the value of vibration force is calculated. By analysising the spectrum of vibration force, in the case when one order inertia force was balanced and two order inertia force was zero ,three order inertia force becomes the main influence factor of vibration force.%以高压星型空压机为研究对象，分析其所受的惯性力和惯性力矩，提出星型空压机的平衡方法。采用Adams软件对星型空压机进行虚拟样机仿真，实现空压机的运动学和动力学仿真，并得出空压机曲柄连杆机构平衡前、后所受振动力的大小。对平衡前后振动力进行频谱分析，表明星型空压机在1阶惯性力完全平衡，2阶惯性力合力为零的情况下，3阶惯性力成为影响振动力大小的主要因素。
