基于传动轴传感器的扭矩路谱采集方法

Acquisition Method of Torque Spectrum Based on Transmission Shaft Sensor

载荷谱是机械部件疲劳寿命设计的重要参数,而传递车辆扭矩的传动轴是高速旋转部件。对运行中用户车辆的扭矩信号进行数据采集和处理,是路谱研究的重要前提。文章设计了汽车传动系统扭矩动态采集和数据处理方法,为路谱研究提供输入数据。

The load spectrum is an important parameter for the fatigue life design of mechanical components, and the transmission shaft for transmitting the vehicle torque is a high-speed rotating component. The data acquisition and processing of the torque signal of the operating vehicle is an important prerequisite for the study of the road spectrum. This paper designs a method of dynamic data acquisition and data processing of vehicle drive system, which provides input data for the research of road spectrum.
