摘要

设计出多轴随机振动控制算法。以NI的PXI RT系统为硬件平台,利用LabVIEW软件开发工具,进行多轴随机振动控制系统的软件开发,所设计的多轴振动控制系统,能够实现六维的随机振动控制,其动态范围达到75 dB。同时在6t、8 t双振动台和某型三轴自由度液压振动台上进行连台控制调试。控制结果表明:经过多帧均衡后,各方向上控制容差均在±3 dB以内。
The multi-axis random vibration control algorithm was designed.Based on the NI PXI real time hardware system,the multi-axis random vibration control system was developed by using LabVIEW software tool.Its dynamic range can be up to 75 dB and it can be applied for the six dimension vibration test.Meantime it has been successfully applied to control the 6 t,8 t double electric-shake table and the three axis-six DOF hydraulic shaking table.The random test result shows that the control quality is satisfied and the control spectrums are within ±3 dB in each dimension.
