摘要
将气动人工肌肉(PAM)应用于车载隔振平台的缓冲执行器,建立五自由度缓冲减振系统的数学模型,以白噪声模拟路面输入,采用模糊PID控制理论对隔振平台隔振性能进行仿真分析。并以隔振平台垂向加速度和垂向位移的最大值、最小值和标准差3项指标进行对比分析。仿真结果表明,在选定的3种工况下,气动人工肌肉光电平台可显著减小路面激励对光电设备的冲击,提高光电设备在运输过程中的可靠性。
Pneumatic artificial muscle （PAM） is used for the buffer actuator of a mobile vehicle-mounted vibration isolation. Five-DOF damping model of system is built up, and white noise is employed to simulate the pavement input. Simulation of the platform is conducted by using simulation software Simulink and fuzzy PID control, and the platform acceleration and displacement of the maximum, minimum and standard deviation of three indicators were analyzed. The results show that vibration-impact was significantly reduced when comparing the mounted PAM platform with the traditional platform under the selected three kinks of working conditions, and the reliability was improved.
