Introduction
The Light Alloy Wheel Torsional Fatigue Testing Machine is designed for torsional fatigue testing of light alloy wheels used in motorcycles and mopeds. It is used to evaluate the torsional fatigue strength, durability, and reliability of wheel assemblies under repeated torsional loading conditions. The machine simulates actual service conditions by applying cyclic torque loads to the wheel specimen, helping determine its fatigue performance and service life. It is widely used in wheel manufacturers, motorcycle manufacturers, research institutes, and quality inspection laboratories.
Application
The Light Alloy Wheel Torsional Fatigue Testing Machine is mainly used for torsional fatigue testing of light alloy wheels for motorcycles and mopeds.
