Electric Vehicle Fatigue Testing MachineElectric Vehicle Frame Vibration Fatigue Test

Electric Vehicle/E-bike Comprehensive Performance Testing MachineFrame Vibration Detection Equipment

I. Product Introduction

The electric vehicle fatigue testing machine simulates repeated vertical vibrations of an electric vehicle under a certain load at a specific frequency for a set number of cycles, then checks for frame damage such as deformation or fracture. This machine allows for adjustable frequency and cycle count, automatically stopping when the set number is reached. It is easy to operate, convenient to use, safe, stable, accurate, and durable. Complies with standards such as GB/T 24158 "General Technical Requirements for Electric Motorcycles and Electric Mopeds," providing data support for product development and quality control.

III. Frame Vibration Testing Machine Operating Procedures;

1. Equipped with stop/power-off memory and breakpoint detection shutdown function; after a sudden power outage, upon restoration, the device automatically saves data and resumes operation with pre-set parameters without manual restart or reconfiguration.

2. Stop Methods: Stops upon reaching the test cycle count; automatically stops and alarms if the specimen is damaged or deformation exceeds limits.

3. The device features a self-diagnostic system that automatically detects faults and displays error codes for easy troubleshooting and maintenance.
