1 Axle Overview
The drive axle assembly fatigue and performance test bench uses an AC dynamometer for driving and loading, simulating actual working conditions to achieve durability and performance tests such as drive axle running-in, life, differential, efficiency, temperature rise, etc., as well as dynamic on-vehicle load spectrum follow-up loading tests; compared with outdoor road tests, it has the advantages of being quick and convenient, having multiple test items, and reducing the workload of test personnel; the control software interface resources are open, easy to expand, and highly automated.

5 Topology
6 Xiangyi Advantages
Modular Design:
Mechanical, electrical, and software all adopt modular design, allowing for the free construction of test environments based on different test objects;
Advanced Measurement and Control System:
Shares a mature platform with other Xiangyi power testing systems, with data acquisition, control, storage, and protection all customizable by the user. The human-machine interface is user-friendly, with a one-button automatic test function to reduce the complexity of testing and lessen the workload of test personnel;
Suitable for different user groups, easy to use, and combines intelligence, openness, and flexibility.
Road Simulation Test & On-vehicle Load Spectrum Test
Can achieve NEDC 、 CLTC 、 WLTP 、C-WTVC and road simulation tests, etc.;
Vehicle parameters such as slip coefficient, vehicle mass, and tire rolling radius can be imported to conduct vehicle powertrain road condition simulation tests.
Safety Protection
Features system-level protection and user-defined multi-level protection measures to ensure the safe operation of the test bench and tests;
The test bench can be connected to a vibration monitoring system to display the vibration curve in the time and frequency domains in real time, the vibration trend during the test process, and automatically alarm and stop when the vibration monitoring threshold is triggered.
Energy Saving and Environmental Protection
Electric dynamometer, energy can be recycled, achieving energy saving and environmental protection
