| 摘 要： | 利用ANSYS软件瞬态动力学分析功能,针对传感/致动器对位配置的压电悬臂梁结构,运用APDL参数化语言实现了压电悬臂梁的主动控制仿真.通过定义瞬态分析所需要的载荷步,把每一时间步中传感器测得的应变量与振动初始参考量的差值作为误差信号,由误差信号与控制增益的乘积来决定致动器的瞬态电压值.仿真结果表明该方法具有可行性.

| Abstract: | Using the capabilities of ANSYS software＇s transient dynamic analysis,the active vibration control of piezoelectric cantilever beam has achieved through the APDL program.The program defines the each load step and the instantaneous value of the strain at the sensors locations at each time step.The difference between the input reference and the sensors signal is called the error signal.Transient voltage of actuator has been decided by the multiplication of the error signal and the control gain.Simulation results show that the method is feasible. |
