Abstract

In this study, we developed a Shock Absorbing System(SAS) to prevent damage in the modular transportation stage, and verified its performance through the road vehicle test application of SAS. The SAS features ① a detachable system, ② a sufficient damping capability, ③ 3-axis vibration control, and ④ a low-frequency vibration isolation target. In order to analyze the performance of the SAS, we conducted road vehicle test under the same conditions before and after the SAS installation. As a result of the test, the vehicle with the SAS showed up to 65% of vibration reduction effect than the vehicle without the SAS. It was confirmed that this SAS system has excellent reduction performance in the vibration of the Z-axis and Y-axis in modular transportation. On the other hand, in future studies, it is necessary to improve the difficulty of installing SAS and inadequate reduction of X-axis vibration.
