What is a wheel radial load fatigue testing machine?
The wheel radial load fatigue testing machine is a device specially used to test the fatigue performance of wheels under radial load under simulated actual driving conditions. It evaluates the durability, reliability and safety of the wheel by simulating the cyclic loads that the wheel receives during driving. It is widely used in automobile manufacturing, rail transportation, aerospace and other fields.
