Cargo Transport Vibration Testing
Using a large 3D shaking table, we reproduce the vibrations and shaking that cargo experiences during transport by rail, trailer, etc. This contributes to examining optimal loading methods and investigating the causes of damage to transported cargo.
Purpose
- To examine optimal loading methods for transported cargo
- To investigate the causes of damage to transported cargo
Features of the Large 3D Shaking Table
- Large shaking table capable of loading a 20-foot container
- Can reproduce vibrations, shocks, and shaking experienced during ship, rail, and trailer transport
- Can faithfully reproduce acceleration, velocity, and displacement of seismic waves from the Great East Japan Earthquake
- Provides analytical data such as acceleration response spectra and transfer functions necessary for earthquake-resistant product design
- Capable of combined excitation (pitching, rolling, yawing), 3-axis, 6 degrees of freedom
- Table size is 2.6m x 6.2m, allowing multiple test specimens to be evaluated simultaneously
- Electro-hydraulic system, suitable for testing liquid tanks or using water tanks, resistant to liquid leakage
- Can vibrate without hydraulic pressure accumulation, enabling long continuous excitation or repeated short waveforms
Reproducible Actual Transport Vibration Waves (for Cargo Vibration Simulation Tests)
- Ship motion: Rolling of car carriers
- Rail transport vibration: Vibrations of North American transcontinental double-stack trains
- Trailer transport vibration: Vibrations of trailers on metropolitan expressways
Examples of Cargo Vibration Simulation Testing
Automobile manufacturer C investigated the causes of damage to cargo racks used for transporting parts to overseas factories by reproducing vibrations experienced during transport. After improving and reinforcing the racks, they also conducted verification tests.
