摘　　要：针对振动筛各弹簧座振幅不平衡的问题,通过振动传感器测量各弹簧座的加速度,分析了振动加速度计算位移过程中的主要影响因素并提出解决方案,利用Lab VIEW设计了信号处理程序,对加速度信号进行高通滤波、小波消趋等处理并计算得到位移及振幅。测量实验及分析结果表明,该技术方法准确、有效,为煤矿技术人员提供可靠依据以进行维护工作,以保障振动筛稳定高效运行。Aiming at solving the problem that each vibrating amplitudes of screen spring seats is different, the acceleration sensors are used for measuring the acceleration signals of each spring seat. In this paper, the possible errors in calculating displacement process are analyzed, and the solutions are put forward. The signal processing program is designed in Lab VIEW,the displacements signals and amplitudes are calculated from acceleration signals after high-pass filtering and wavelet-analysis detrend. The results have shown that the used method is accurate and effective, which can provide coal mine technicians with reliable information for maintenance, so as to ensure the vibrating screen can operate in a stable and efficient state.
