摘要: 采用建立离散系统动力学方程的矩阵法，建立了双旋转偏重激振的惯性往复振动设备的动力学方程，该动力学方程与两驱动电机的状态方程一起构成了惯性往复振动设备机电耦合的数学模型．通过分别对不同阻尼、不同电机功率时数学模型的数值仿真和对仿真结果分析，揭示了惯性振动设备瞬态过程的实质，提出了减小振动体瞬态振幅和缩短瞬态过程的新方法．为该类设备瞬态过程的智能控制和工程设计提供了可靠的数学模型．Abstract: The dynamical equations for a inertial reciprocating machine excited by two rotating eccentric weights were built by the matrix methodology for establishing dynamical equations of discrete systems.A mathematical model of electromechanical coupling system for the machine was formed by combining the dynamical equations with the state equations of the two motors.The computer simulation to the model was performed for several values of the damping coefficient or the motor power,respectively.The substance of transient behavior of the machine is unveiled by analyzing the results of the computer simulation,and new methods are presented for diminishing the transient amplitude of the vibrating machine and improving the transient behavior.The reliable mathematical model is provided for intelligent control of the transient behavior and engineering design of the equipment.
