The frame vibration test machine (dual vibration system) is a multi-axis composite vibration testing device specifically designed for the frame structures of automobiles, motorcycles, electric vehicles, etc. By simultaneously applying lateral (X/Y axes) and vertical (Z axis) bidirectional vibration loads, it accurately simulates the jolts, impacts, and high-frequency vibrations of real roads, comprehensively verifying the fatigue life, weld strength, modal characteristics, and resonance risks of the frame. This equipment is widely used in vehicle manufacturing, component production, R&D laboratories, and certification institutions to ensure that the frame complies with international standards such as ISO 16750, GB/T 31467.3, and ASTM E756, providing scientific guarantees for vehicle safety and durability.
Application scope
Designed to simulate the vertical vibration test standards for scooter frames, the scooter frame is fixed on the fixture of this test machine and subjected to fatigue loading of a certain frequency, load, and test cycle.
Reference standards: JIS D9401 5.0 GB17761
Core functional modules
Dual-axis composite vibration test
Multi-degree-of-freedom loading: Simultaneous superposition of X/Y-axis horizontal vibration (frequency 1~200Hz, acceleration 0~50g) and Z-axis vertical vibration (frequency 1~100Hz, acceleration 0~30g) to simulate complex road conditions.
Random/sinusoidal wave combination: Supports sinusoidal sweep, random vibration and road spectrum reproduction (import actual measured road spectrum data), covering urban, off-road, high-speed and other driving scenarios.
Intelligent environmental coupling test
Temperature and humidity simulation: Optional high/low temperature chamber (-40℃~+120℃, humidity 10%~95% RH) to verify the impact of temperature stress on frame fatigue.
Salt spray corrosion test: Salt spray is sprayed according to ASTM B117 standard to test the anti-corrosion performance of frame welding points and metal parts.
High-precision data monitoring and analysis
Dynamic parameter acquisition: Real-time monitoring of frame strain (accuracy ±0.5% FS), displacement (±0.01mm), and vibration acceleration (±1% FS), generating fatigue damage cloud map and S-N curve.
Modal analysis: Identify the natural frequency, mode shape and damping ratio of the frame through an impact hammer or shaker (optional) to optimize structural design.
Failure warning: AI algorithm analyzes stress concentration areas, predicts crack propagation trends and triggers shutdown protection.
