Abstract

The invention discloses a friction test system, which comprises a test platform, and is characterized in that the test platform is provided with a tensile machine module used for clamping a sample strip and capable of driving the sample strip to move up and down; a pressure clamping module connected with the tensile machine module and used for clamping two sample pieces for clamping the sample strips along the two sides respectively; a control module connected with the pressure clamping module and used for controlling the heating temperature and the clamping force of the two sample pieces; andan industrial personal computer connected with the tensile machine module and used for controlling the speed and the displacement of the sample strip. According to the friction testing system, clamping and friction testing of three different kinds of materials can be realized; continuous controllability of various influence factors can be realized, the friction performance of three different materials in mutual contact under various working conditions can be truly simulated, and the real-time change rule of each factor and the influence of each factor on the friction performance can also be tested; meanwhile, due to the modular structural arrangement of the system, the system is easy and convenient to operate, high in replaceability, low in cost and wide in application range.

Description

technical field [0001] The invention relates to the technical field of friction testing, in particular to a friction testing system. Background technique [0002] One-third to one-half of the world's energy is consumed by friction, and the failure of various mechanical parts due to wear accounts for more than 50% of all failure parts. For example, in the automotive industry, friction between moving parts causes energy loss and reduces fuel efficiency. About 10% of the energy consumption of a car is caused by the phenomenon of friction and wear, and the friction between engineering materials and the surface of automotive components reduces by about 3% to 5% fuel efficiency. Friction is also a key factor in various forming processes. For example, in the rolling forming of aluminum foil or aluminum plate, friction conditions directly affect the life of the roll and the performance of the product. The calculation of the rolling force must also accurately determine the average v...
