TESTING EQUIPMENT
High-Low Temperature Test Chamber
The temperature variation range meets -60°C~+180°C, and it can be controlled by program and fixed - value. Combined with the MTS 850 high - speed performance test bench, it meets tests that require the overall test environment to meet extreme temperature requirements, such as low -
temperature durability tests.
Programmable High-Low Temperature Test Chamber
The temperature variation range meets -40°C~+200°C, and it can be controlled by program and fixed-value, meeting tests that require temperature adjustment such as temperature characteristics and dynamic low - temperature sealing tests.
Spring Fatigue Test Bench
It is mainly used for the durability performance testing of shock absorber springs, and the testing capability meets the spring fatigue durability test required by JB/T 10416-2004.
Double-acting Fatigue Test Bench （two sets）
The testing capability meets the upper and lower end double-acting bench durability test required in QC/T 491 - 2018, including a temperature control system. It can also meet durability tests such as hydraulic durability tests, strut assembly durability tests, and mud durability tests.
Microcomputer - controlled Electronic Universal Testing Machine
It is used for material mechanical property tests and shock absorber component connection strength tests. It can conduct performance tests such as tension and compression of metal materials, and also conduct connection strength tests between the piston rod and the upper connection seat, connection strength tests between the oil storage cylinder and the lower connection seat, bending strength tests of the piston rod itself, etc.
STEP LAB Performance Testing System
It is mainly used to conduct shock absorber performance tests such as the indicator diagram test, gas rebound force test, and friction test required in QC/T 491-2018.
MTS 320 Vehicle Fatigue Test Bench
Combined with the high-precision data acquisition system of HBK in the United States, after collecting real-vehicle data on complex road conditions such as bumpy roads, high-speed curves, and slopes, it restores the corresponding road conditions to the indoor environment for testing or comfort experience. It can more efficiently detect the source of vehicle abnormal noises and simulate the body fatigue loads during long-term vehicle use.
Flexible Test Bench
With horizontal and vertical double cylinders as the core, the actuator cylinders can be freely combined or independently controlled, flexibly simulating various complex working conditions that shock absorbers may encounter. It can complete tests for various special structures, and can realize axial durability performance tests for rubber bushings, shell durability tests for shock absorber strut assemblies, and other test items.
MTS 850 High- speed Performance Test Bench
It is mainly used for the calibration of various types of nitrogen shock absorbers for electronic control, racing, and civilian use. It also meets the performance tests such as the indicator diagram characteristic test and friction test required in the standard QC/T 491-2018. When combined with a high-low temperature test chamber, it can conduct temperature characteristic tests, dynamic low-temperature sealing tests, etc.
MTS 850 Comprehensive Performance Test Bench
In addition to meeting the basic tests such as the indicator diagram characteristic, friction character-istic, and anti-foaming test in QC/T 491-2018, combined with the MTS temperature control system, it can meet the special requirements of vehicle manufacturers such as Great Wall and BYD for valve system high-speed durability and high-temperature durability tests that require temperature monitoring.
MTS 852 Durability Test Bench
It specializes in the durability limit verification of shock absorbers, expanding the testable space and force value upper limit of shock absorbers. Equipped with the temperature control system independently developed by K-MAN, it realizes real-time temperature monitoring and intelligent start-stop functions, meeting the requirements for shock absorbers to conduct valve system high-speed durability, high - temperature durability, stretching durability tests, bench durability tests, etc.
1/4 Suspension Test Bench
It is used to simulate the installation method of shock absorbers in the 1/4suspension structure of a real vehicle chassis. It replicates the 1/4suspension structure of a real vehicle at a 1:1 ratio, highly simulating the dynamic load scenarios of shock absorbers, and meets the durability verification tests of 1/4 suspension systems for different vehicle models.
