The Kokusai 3-axis four poster excitation testing system has been designed to focus on simulating super low frequency and displacement of road vibration using its especially engineered servo motor manipulation technology. Super low end displacement and vibration frequency from road vibration has been known as one of greatest factors causing vehicle's vibration, noise and ride discomfort.
The Kokusai system optimizes and applies the greatest features of electric servo motor technology such as; accurate reproducibility and precision stroke control regardless of stroke distance within system. G forces of up to 8 Gs are possible in the vertical direction and 5 Gs in the horizontal axes. The overall system has automatic wheel base adjustment and tread base adjustment. Each independent post can run various shaking profiles including random, triangle and field waveforms.
