直线电动压缩机活塞的动力学分析

介绍了直线电机驱动的分体式压缩机的结构及动作原理，并从理论上分析了它的动力学特性，推导了理想条件下活塞的动力学方程，并作了数值求解。研究表明其动力学特性不同于传统的往复式压缩机，所受惯性力是非简谐周期力，运动学特性属于非简谐周期性运动。研究结果为直线电机驱动的分体式压缩机的设计分析提供了理论依据，可使压缩机性能更优越，结构更合理。

Dynamic Analysis of Piston on Linear Motor Drive Divided Compressor

The action principle and the structure of the divided compressor driven by the linear motor are introduced, and its kinematic character is analyzed in the theory, the kinematic equations of the ideal condition are deduced, and the numeric solution is done. The research shows that its dynamic character is different to the conventional reciprocating compressor, the inertia force of it received belongs to anharmonic cyclic force, and the kinematic character belongs to anharmonic cyclic motion. The conclusions offer the theoretical basis for the design and analysis of the linear motor drive divided compressor, which make its performance better and its structure more proper.
