Selection Guide: How to Choose the Right Frame Vertical Fatigue Testing Machine for You?
1. Select by Vehicle Type
Vehicle Type Recommended Load Range Recommended Frequency Range Recommended Configuration
Bicycles/Children's Bicycles 0~3 kN 5~20 Hz Electric servo type, high cost performance
Electric Bicycles/Assist Bicycles 0~5 kN 5~15 Hz Electric servo type or small tonnage electro-hydraulic servo
Light Motorcycles 0~10 kN 3~10 Hz Electro-hydraulic servo type
Heavy Motorcycles/Three-wheelers 0~20 kN or higher 1~5 Hz Large tonnage electro-hydraulic servo type
2. Select by Testing Standards
ISO/EN Standards: Confirm whether the equipment meets the requirements of standards such as ISO 4210 and ISO 11243 for load, frequency, and cycle count.
National standards GB: Must comply with requirements such as GB 3565 and GB 17761 (Safety Technical Specifications for Electric Bicycles).
Enterprise standard: Customized load spectrum and test procedures based on the enterprise standard documents provided by the customer.
3. Selecting Models Based on Test Functions
Function Module Applicable Scenarios Recommended Configuration
Single-Point Vertical Fatigue Standard compliance testing (e.g., ISO 4210) Single-channel electric servo + basic software
Multi-channel Composite Loading Research and development-level complex condition simulation (e.g., vertical + horizontal + lateral) Multi-channel electro-hydraulic servo + coordinated control software
Stiffness Testing Material comparison, design optimization High-precision displacement sensor + stiffness analysis module
Spectrum Fatigue Real road spectrum reproduction, life prediction Load spectrum editing module + high-speed data acquisition
High/Low Temperature EnvironmentAdaptability verification in extreme environments Environmental chamber interface + high/low temperature actuator
Installation and Environmental Requirements
To ensure test accuracy and equipment lifespan, please ensure that the installation environment meets the following conditions:
The ground should be flat, solid and free of vibration. A reinforced concrete foundation is recommended, with a thickness of no less than 300 mm and a bearing capacity of no less than twice the weight of the equipment.
Space: Reserve an operation space of ≥ 1.5 m around the main unit, and ensure there is a heat dissipation space near the control cabinet.
Power supply: Stable power supply, voltage fluctuation ≤ ±5%, grounding resistance ≤ 4Ω.
Ambient temperature: 10℃ to 35℃.
Humidity: ≤ 85% RH, no condensation.
Hydraulic source (electro-hydraulic servo type): It should be placed in an adjacent room or sound insulation measures should be taken. The length of the oil pipe should be no more than 10 meters.
