Description

Technical Field

[0001] This utility model relates to the field of component testing technology, and in particular to a shock absorber performance testing device for vehicle engineering. Background Technology

[0002] Shock absorbers are the core damping components in a vehicle's suspension system. By utilizing the resistance of fluid flow or the compression characteristics of gas, they dissipate the vibration energy generated by road bumps during vehicle operation by converting it into heat energy, thereby suppressing excessive vibration of the vehicle body and wheels, reducing impact, and improving ride smoothness, comfort, and handling stability. At the same time, they reduce wear on various vehicle components caused by vibration and extend their service life.

[0003] The shock absorber performance testing device is a specialized device designed to evaluate the various performance characteristics of vehicle shock absorbers. It simulates actual operating conditions such as vibration, load, and temperature during vehicle operation, applies specific force or displacement excitation to the shock absorber using an excitation system, and collects parameters such as damping force, displacement, and velocity in real time using sensors. After data processing and analysis, it outputs indicators such as the damping characteristics, response performance, durability, and environmental adaptability of the shock absorber, providing a scientific basis for the research and development optimization, production quality inspection, and performance evaluation of shock absorbers.

[0004] In existing technologies, shock absorber performance testing devices still have compatibility issues with different types of shock absorbers. Some special shock absorbers of different sizes are incompatible, the working condition simulation is not comprehensive enough, and it is difficult to fully reproduce the complex road surface and multi-directional force coupling scenarios when a vehicle is driving. Some devices are cumbersome to operate and have low clamping efficiency, and high-end equipment is expensive. The stability and reliability of the system in long-term high-intensity testing also need to be further improved. Therefore, a shock absorber performance testing device for vehicle engineering is proposed to solve the above problems. Utility Model Content
