Wheel Radial Fatigue Testing Machine
The Wheel Radial Fatigue Testing Machine mainly simulates road conditions. The excitation speed-regulating motor drives the drum to achieve stepless speed adjustment, enabling tests at different vehicle driving speeds.
Applications
Automotive wheel radial fatigue testing to evaluate wheel durability and service life under simulated road conditions.
Performance testing of aluminum alloy wheels and steel wheels for structural strength and reliability evaluation.
Wheel design verification and quality inspection for passenger cars, commercial vehicles, and new energy vehicles.
Fatigue durability testing of tires and wheel assemblies under cyclic radial loads.
Widely used in automobile manufacturers, wheel manufacturers, automotive component suppliers, research institutes, and testing laboratories.

Structure and function
The Wheel Radial Load Fatigue Testing Machine mainly consists of the main machine, computer control unit, electrical control unit, and test fixtures. It simulates road conditions, and the excitation speed-regulating motor drives the drum to achieve stepless speed adjustment for testing under different driving speeds.
The loading bracket adopts low-friction linear components for transmission and is driven by a servo motor with closed-loop control. The load sensor measures the applied load, realizing closed-loop control of the fatigue testing machine and providing an emergency stop function in case of fatigue failure.
