Abstract

Practical work results on the development of an experimental stand for wear tests of millstones for grinding of grain are presented. When designing the stand, the method of testing for abrasive wear during friction against loosely fixed abrasive particles was used. A feature of the test bench is that the movable and fixed millstones are made cone-shaped and during testing are in oscillatory motion relative to the stationary stand platform. The test bench is equipped with a drive shaft speed sensor, a temperature sensor and a strain gauge force sensor. The Arduino IDE microcontroller software is used to process the incoming data. The software allows one to display the current values of the measured parameters on the screen of a personal computer monitor. All data are saved to files for further processing, which significantly reduces the time for experimental studies.

磨石磨损试验实验台

摘要

介绍了磨石磨粒磨损试验台开发的实际工作成果。在设计支架时，使用了与松散固定的磨料颗粒摩擦时测试磨料磨损的方法。该试验台的特点是活动磨石和固定磨石均制成锥形，在试验过程中相对于固定台作摆动运动。试验台配备有传动轴转速传感器、温度传感器和应变仪力传感器。Arduino IDE 微控制器软件用于处理传入的数据。该软件允许人们在个人计算机显示器的屏幕上显示测量参数的当前值。所有数据都保存到文件中以供进一步处理，这显着减少了实验研究的时间。
