PJW-20-2 Wheel Radial Fatigue Testing Machine
I、 Application of wheel radial fatigue testing machine
Wheel radial load fatigue testing machine is mainly used for dynamic radial load fatigue test of passenger cars, light trucks and heavy-duty wheels. It is a necessary equipment for wheel testing. It mainly simulates the fatigue resistance of the vehicle under load and detects the fatigue resistance under long-time operation. Reference standard:
1. The testing machine is designed and manufactured according to GB standards, ISO, SAE, JIS, via, TUV and other standards.
2. QC / T 221 performance requirements and test methods for automobile light alloy wheels
3. GB / T 5334-2005 passenger car wheel performance and test methods
4. Gb3581-2018 safety performance requirements and test methods for automobile wheels
5. GB / T 18861 − test method for rolling resistance of automobile tires
6. ISO 18164 - Test Method for rolling resistance of automobile tires
7. SAE j1270 - Measurement of tire rolling resistance of passenger cars, light trucks, highway trucks and buses
8. Iso-fdis 28580 method for measuring rolling resistance of passenger car, truck and bus tires
