摘要
介绍用 STD 工业标准总线微机实现的拖拉机座椅振动加速度测试仪,并从误差分析出发提出了振动加速度测试中采样周期的自适应控制问题,以及限值滤波中最大值的估计方法。还讨论了周期性负载对频率稳定性的影响。
A measuring instrument is introduced,which is composed of STD-BUS microcomputer.The problem in adaptive control of sample period in measuring vibration acceleration and the method of estimating maximum in norm filter are put forward.The effect of periodic load on frequency stability is discussed.
