1. Application:
This equipment is suitable for static, dynamic, fatigue, creep and other tests related to automotive rubber springs.
The system is equipped with special tooling for rubber components, with good versatility and advanced performance. It can also be used for low-cycle fatigue and high-cycle fatigue tests on various metal and non-metal materials. It can also conduct fatigue and static mechanical performance tests on various structural parts, components and assemblies.
If necessary, it can also be used for loading tests of other structural parts, components, and assemblies.
The system adopts electro-hydraulic servo technology and computer automatic control system operation. It has the characteristics of good professionalism, high reliability, advanced technology and wide range of use.
2. Standards:
Meet relevant standards such as QC/T491-1999 "Dimensional Series and Technical Conditions of Automotive Tubular Shock Absorbers" and QC/T545-1999 "Bench Test Methods for Automotive Tubular Shock Absorbers" to conduct shock absorber related tests, including: power test, speed characteristic test, internal friction resistance test, fatigue test, etc.
