KDPJW-20 Model Automotive Wheel Radial Load Fatigue Tester
I. Overview:
1. Application: This testing machine is primarily used for radial load fatigue tests on passenger car wheels. It operates in a single-station testing mode and is randomly equipped with a test accessory (tailored to the dimensions or design of the test piece provided by the customer). Additionally, two more testing stations are available (with the option for different loading loads on each station).
2. Reference Standard:
2.1 GB 36581-2018 "Automotive Wheel Safety Performance Requirements and Test Methods"
2.2 GB/T 5334-2021 "Passenger Cars - Wheel - Requirements and Test Methods for Bend and Radial Fatigue Performance"
