New product release | ｜LBSNJ‑30 wheel radial load fatigue testing machine, which helps to test the reliability of wheel products.

In order to meet the needs of automobile, tire and wheel parts enterprises for testing the durability of products, our company newly developed * **LBSNJ‑30 wheel radial load fatigue testing machine * * officially launched. The equipment simulates real road driving conditions, completes the radial load endurance fatigue test of wheel tire assembly, and provides reliable hardware support and data guarantee for wheel product development iteration and quality control.

The testing machine uses a drum to simulate the road conditions, and the motor drives the drum to rotate. Through the hydraulic servo closed-loop loading system, the rim tire assembly is pressed against the surface of the drum, and the durability test can be carried out according to the preset speed and load. The equipment is equipped with an independent microcomputer control system. Based on the Windows operating platform, it realizes the setting of test parameters, real-time collection of process, dynamic data display and automatic storage, and directly outputs the test report in Excel format, which completely records the key test data such as test speed, loading load, running time, accumulated mileage, tire radius and environmental temperature, and supports fault diagnosis and hierarchical management of authority. The operation is intuitive and convenient.

The main equipment consists of a high-strength frame, a drum drive assembly, a station loading assembly and a safety protection net. The diameter of the drum is φ Φ1700mm, and the radial runout is ≤0.10mm, which ensures the high accuracy of the simulated road surface; The loading part is equipped with high-precision load sensor and built-in displacement sensor, and the linear guide rail and imported bearing ensure the motion accuracy. The equipment is equipped with multiple safety protection mechanisms: automatic return protection of tire pressure loss, return in place detection, and interlock shutdown alarm of protective door to ensure the safety of testers and equipment in all directions.

# # Highlights of core technology

1. ** Hydraulic servo closed-loop loading * *: the maximum test load is 3T, the load control accuracy is 1%, and the force control is stable and reliable;
2. ** Wide speed test interval * *: The test speed covers 1140 km/h, and the closed-loop speed control is suitable for multi-specification tire testing;
3. ** Wide sample adaptation * *: It can be adapted to tire assemblies with specifications ranging from 8 inches to the maximum outer diameter of 1100mm;
4. ** Independent intellectual property software * *: Self-developed testing software, which supports the editing of test procedures and self-defined test procedures to meet the needs of personalized tests;
5. ** High-reliability component configuration * *: The load cell, servo valve, linear guide rail and spindle bearing are selected from well-known brands at home and abroad, with strong stability and long service life.
