Wheel Radial Load Fatigue Testing Machines

Model: UT1015, ISO 8644 Radial load durability test

Wheel radial load fatigue testing machine is used to test the operational strength of wheels under load. By applying prolonged force to the wheels, it can assess the overall strength of the wheels as well as the strength and fastening of each component connection. It can also be used to test the fatigue resistance characteristics of the wheel tires.

The wheel radial load fatigue testing machine is mainly composed of a speed adding system, a radial force adding system, wheel mounting fixtures, computer testing software, and a control unit.
Currently, there are two types of wheel radial load fatigue testing machines: single-station and dual-station. Customers can choose according to their testing requirements. If testing is intensive, a dual-station machine can be selected. For specific information, please consult us.



General introduction

UT1015 Wheel radial load fatigue test machine, also known as the microcomputer control motorcycle light alloy wheel radial load fatigue test machine or motorcycle tire durability test machine or motorcycle tire life test machine. This test machine is mainly used for radial load fatigue test of light alloy wheels of motorcycles and mopeds.

Wheel Radial Load Fatigue Testing Machines

The wheel radial load fatigue testing machine is mainly composed of a speed adding system, a radial force adding system, wheel mounting fixtures, computer testing software, and a control unit.
Currently, there are two types of wheel radial load fatigue testing machines: single-station and dual-station. Customers can choose according to their testing requirements. If testing is intensive, a dual-station machine can be selected. For specific information, please consult us.


Mainly operates by using a power mechanism to drive the large intermediate hub to rotate, thereby driving the test wheel. The overall performance of the wheel is tested by applying a constant radial force. The available speed options are currently 80 km/h, 120 km/h, and 160 km/h. The higher the speed, the greater the required kinetic energy.

The detection of radial load fatigue testing is mainly conducted through flaw detection inside the wheel after the test. The common issue that may occur is cracking. In the current market, wheels do not directly break during operation. Even in the event of a blowout while in use, the hub remains solid and robust.

  • Application field

The test machine is mainly composed of the main host, the microcomputer control unit, the strong electric control unit, the test accessory, etc.

1, The host uses welding structure design and manufacture, horizontal loading design, large drum using international standard design, design diameter of 1707.6mm, as realistic as possible to simulate road condition, excitation speed motor drive drum to achieve no-stage speed, achieve different driving speed test, load bracket using low damping linear component drive, servo motor drive closed-loop control, load sensor to complete the measurement of the load, so as to achieve fatigue test load control, and damage to the emergency control of the fatigue test load.

2, The test process computer automatic control, test load, test mileage through the computer set, the computer automatic control servo motor load, to achieve the test mileage automatic shutdown.

3, The computer control system is equipped with safety protection, and can be automatically unloaded and shut down in the event of unexpected conditions such as load, flat tire and wheel damage.

Configure the strong power control box, complete the drive control of the excitation speed control motor, with power on, off, motor start, stop, speed increase and decrease and other operating functions.

Microcomputer control unit, configuration computer, computer for Lenovo brand machine, mainstream configuration, computer built-in signal amplification A/D conversion card board, complete the sensor signal amplification and signal mode conversion, computer software for WINDOWS platform software, with test parameter settings, dynamic test waveform display, test data storage, output test report and other functions.


The printer prints the test report.

The integral shield effectively ensures the safety of the operator, the safety door built-in interlock, the configuration of a powerful fan, the air outlet direction is adjustable, and can be pumped and wind switching.

Test equipment should have a test drum with diameter of not under 400 mm, drum surface should be smooth, soft and its width is larger than tyre width tested

Test drum should be rotated at unchanged speed;

Test equipment should permit to impact a unchanged radial load (deviation of radial load change in the test is ±5%) on wheels in the direction of wheel center to drum center and ensure so that wheels always contact with test drum.


Assemble rim with tyre pumped to minimum pressure equal to the pressure marked on wheel into test equipment (see figure B1) in the method as used to assemble vehicle wheel. Test drum is rotated while impacting radial load Q as per B.2.1.

The number of turns of test drum is not under 5 x 105  turns.


Motorcycle manufacturers: Test the product quality of wheel suppliers to ensure compliance with the durability requirements of the complete vehicle.

Passenger car manufacturers: Assess the dynamic rotational bending fatigue strength of wheels when cornering.

Third-party testing agencies: Provide wheel fatigue performance certification services to help companies meet industry access standards.
