Multi-Cargo Simulator (MCS): For Tests of Shock and Vibration during Transportation & for Tests of Transport Machinery's Resistance to Shock and Vibration
We conduct for our customers various simulation tests for shock and vibration, and for temperature and humidity. The tests for shock and vibration use a large-scale 3-D Physical Axial System, and the tests for temperature and humidity use an Atmospheric Environmental System. The simulations can be used to study the most appropriate stowing and packing methods for cargo by reproducing the actual vibration patterns of transportation. In fact, the system can simulate the seismic waves of the earthquake that struck southern Hyogo Prefecture in 1995.
Since the Multi-Cargo Simulator started operation in 1995, it has been used not only for multi-cargo simulations but also for shock and vibration tests for precision instruments, furniture, and other such items.
Summary
The large scale 3-D Physical Axial System perfectly simulates vibrations, shocks, the rolling motions of cargo in transportation, and even seismic vibrations as strong as those that hit southern Hyogo Prefecture in 1995. These simulations offer highly accurate and reliable data for studying product design and the most appropriate stowing and packing methods for cargo.
The Atmospheric Environmental System can simulate temperatures in the range of minus 15°C to 80°C (5°F to 176°F); therefore, it can be used to test the heat-resistance performance of cargo and products in transport.
Features
- Vibration is applied in the actual wave patterns that occur during transportation.
The MCS can simulate the actual vibration patterns that occur during transportation in the North American Transcontinental Railroad systems and trailers. - The MCS can perform vibration tests compliant with JIS and IEC standards.
The MCS can perform vibration tests on railway-car attachments compliant with JIS and IEC standards. - The MCS can perform shock and vibration tests by creating artificial earthquakes, applying the same magnitudes of seismic vibrations as those of various earthquakes that have occurred in Japan and elsewhere.
The MCS can simulate the same magnitudes of seismic vibrations as those that occurred in the earthquakes of southern Hyogo Prefecture, Miyagi-Oki, and Taft; the artificial seismic vibrations of NTT and NEBS; and can perform earthquake-resistance tests in compliance with EN and IEC standards. - The maximum rolling angle is 20 degrees.
The MCS can simulate the rolling motions of a ship. - The MCS can perform multiple tests by combining the Physical Axial System with the Atmospheric Environmental System.
Examples
- For a manufacturer of electrical equipment, we conducted a performance test on the packing and stowing method of electrical equipment by simulating vibration during transportation.
- For a manufacturer of railway-car devices, we demonstrated that a device has sufficient strength to withstand car vibrations by simulating the vibrations generated in a moving car.
- For a manufacturer of control equipment, we conducted a performance test in compliance with IEC standards on some control equipment's resistance to shock and vibration to confirm that the equipment met the specifications for such resistance as required by the manufacturer's client.

FAQ
- Q: Is it possible to operate the Physical Axial System continuously at length?
- A: Yes, it is possible to operate the Physical Axial System for a long time around the clock, as the system is installed with simulation software that enables continuous operation for long periods of time, and is also equipped with a cooling system for the hydraulic oil.
