摘要
摘要:本文的目的是研制一种用于测量滑动运动平面摩擦联轴器摩擦的装置(“销盘”式)。在我们实验室制造的摩擦测量装置上,我们可以测量不同加载条件、速度、时间和材料耦合下的摩擦力、摩擦系数和磨损。对于摩擦力和摩擦系数的测量,主要采用电阻式张力传感器。使用DataQ DI 245数据采集板,可以在-10 ÷ +10 mV范围内记录高达2 kHz的频率,分辨率为13位。为了测试该装置的功能,对铸铁圆盘上的钢销进行了初步测试,测试了不同的法向推力值。对装置进行校准,并在计算机上记录和处理测量结果。
Tribometric Device for Determining Friction Forces and Friction Coefficients in the Case of Dry Friction of Materials
Abstract The aim of the paper was to develop a device (“pin-on-disc” type) for the measurement of friction in plane friction couplings with sliding movement. On tribometric device (made in our laboratory) we can measure the friction force, friction coefficient and wear, for different loading conditions, speeds, time and material coupling. For the measurement of the frictional force as well as of the coefficients of friction, mainly the method with a resistive tensiometric transducer is used. With a DataQ DI 245 data acquisition board it is possible to record up to 2 kHz frequencies in the range of -10 ÷ +10 mV with a resolution of 13 bits. To test the functionality of the device, a preliminary test was carried out for a steel pin- on- cast iron disc, for different values of the normal pushing force. The device was calibrated and the measurement results were recorded and processed on the computer.
