基于ADXL345的铁路列车振动舒适度检测与评价

Railway Train Vibration Comfort Testing and Evaluation Based on the ADXL345

随着国民经济的发展,人们对于乘坐铁路客车的舒适度的要求也越来越高,设计一套列车舒适度的检测与评价系统,对车辆的设计、制造和管理部门不断改进、提高列车的舒适度起着重要的参考作用。系统采用近年推出的ADXL345型数字加速度计采集加速度信号,使得系统的硬件电路更加简单,测量精度更高,抗干扰性能更加强大。

With the development of national economy, people who take passenger trains have higher requirements for comfort. A set of train comfort testing and evaluation system provides important reference for train designers, manufacturers and managements to improve the sense of train comfort. The system adopts the latest ADXL345 digital accelerometer to acquire acceleration signal, which makes the system hardware circuit easier with more accurate measurements and stronger anti-interference performance.
