Problems solved by technology
[0004] Using the static friction coefficient testing machine currently on the market, the polyurethane material needs to be made into the sample size required by the static friction coefficient testing machine before measuring the static friction coefficient of the material, and the test needs to be carried out in a department with a friction material testing machine or by purchasing a friction testing machine by itself , time-consuming and labor-intensive, and can only measure the static friction coefficient of the polyurethane material itself, and cannot restore the static friction coefficient of the entire polyurethane tire under real working conditions to the greatest extent.

Embodiment Construction
[0044] Friction is the most common phenomenon in the industrial manufacturing process. This phenomenon causes uneven deformation, wear, and slippage of mechanical parts, which has a huge impact on the working performance and service life of mechanical parts. With the continuous improvement of the use requirements of mechanical parts, the performance parameters are becoming more and more accurate, and the measurement of the static friction coefficient has become an inevitable requirement for test characterization.
[0045]At present, the automatic paint removal equipment for large storage tanks at home and abroad mainly focuses on wall-climbing robots. The wall-climbing robot has two basic functions: the adsorption function on the steel wall and the walking function. The adsorption function of the wall-climbing robot is realized by the adsorption force between the permanent magnet and the steel plate material, and the walking function is realized by the motor-driven tire. like...

The present application provides a test device and method for measuring the coefficient of static friction of tires, including a measuring device, a tension component and a computer system. The measuring device includes a first flat plate, a second flat plate, a third flat plate, a screw, a pressure sensor and a U-shaped plate . Positive pressure can be applied to the tire to be tested by tightening the nuts at the connection between the first flat plate, the third flat plate and the screw rod, and the pressure between the second flat plate and the third flat plate can be measured by a pressure sensor. The tension component exerts a pulling force away from the U-shaped plate on the screw until the first flat plate, the second flat plate and the tire to be tested move relatively. The computer system receives the pressure value data sent by the pressure sensor and the measurement data sent by the tension component in real time, and analyzes and calculates the static friction coefficient of the tire to be tested.
