板弹簧用作称重弹性体时的迟滞与补偿
摘要
采用车辆板弹簧作为称重传感器的弹性体检测车辆载荷时
板弹簧的迟滞严重影响了载荷检测的精度。以一种卡车的后车桥板弹簧为例
介绍采用单片机对车辆板弹簧迟滞现象进行补偿的方法。这种方法简单可行
试验结果表明:补偿后
迟滞对称重结果的影响可减小为原来的20%
提高了这种称重装置的检测精度和实用性。
Abstract
When vehicle leaf springs are used as elastic body of the weighing transducer to measure vehicle load
the measuring precision is severely influenced by the hysteresis of leaf springs.Taking a sort of truck rear axle leaf springs as an example
a way to compensate the hysteresis of vehicle leaf springs with micro-controller is presented.This method
which is simple and practicable
can reduce the influence of hysteresis on measuring results to 20% of the original
as shown by test results
thus the measuring precision and practicability of this weighing device is greatly improved.
