摘要
本文利用子结构导纳法建立了柔性基础多支承多扰源主动隔振系统模型。对系统中振动功率流的传递进行了理论分析和数值计算。计算结果表明 ,前馈控制策略可有效地隔离柔性基础上马达的周期性扰动 。
An active isolation system of multi mounts and 2-DOF disturbances mounted on a flexible receiver is presented,using the sub system mobility method.The transmission of power flow of the active isolation system is investigated theoretically and numerically.The results of simulation show that periodic vibration transmission from a motor to a flexible can be isolated effectively by the feedforward control strategy,and the vibratory energy at the systems natural frequency is attenuated obviously.
