摘要
介绍了设定多用途试验车体的部分地板结构为悬吊地板结构,实施定置激振试验,确认了这种地板结构具有降低几百赫兹以下低频带振动的效果,并验证了连接多块地板的悬吊地板结构的减振效果。
The vibration test on multi-purpose test vehicle in which part of the floor panels are suspended floor structure is conducted to confirm that the suspended floor structure can reduce the low frequency vibration in a range of hundreds of Hertz.The damping effect of the suspended floor structure connecting several floor panels is also verified.
