Embodiment Construction

[0026] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] like figure 1 As shown, the present invention provides a friction pair temperature testing method, comprising the following steps:

[0028] S1. Arrange thermocouples on the moving plate of the friction pair, and install an infrared optical fiber thermometer within a certain distance from the moving plate;

[0029] like figure 2 As shown, considering the size of thermocouples and strain gauges, and without affecting the friction effect, the way to arrange thermocouples is: open 5 slots on the moving plate, and each thermocouple is buried in 1 slot, so that To prevent the thermocouple from being damaged by friction, the 5 grooves are located at different positions with 5 different radii on the moving plate, and...

Abstract

The invention relates to a method for testing the temperature of a friction pair, belonging to the technical field of temperature testing. The present invention designs a method for testing the temperature of the friction pair. Due to the reasonable design of the steps, the method can not only measure the position and time of the highest temperature generated during the friction process, but also reduce the impact of the measurement system on the friction process of the friction plate. It also meets the requirements of high measurement speed and precision.

Description

technical field [0001] The invention relates to the technical field of temperature testing, in particular to a method for testing the temperature of a friction pair. Background technique [0002] During the joint process of the friction plates, a large amount of kinetic energy is converted into heat energy, causing the surface temperature of the friction plates to rise rapidly, resulting in high heat zones and thermal deformation on the friction plates, which seriously affect the performance and reliability of the transmission system. The temperature distribution of the friction plate is of great significance for revealing the occurrence law of thermal-mechanical instability between friction pairs and correctly judging the design effect of the friction plate. [0003] In the prior art, it is impossible to provide a friction pair temperature testing method capable of measuring the position and time of the highest temperature generated during the friction process, with fast me...
