The vibration and noise level declined obviously through the isolation around the bearing as well as the adoption of damping alloy as the material of the gearbox body.
通过轴承部位的隔振以及箱体采用高阻尼合金材料，齿轮箱的振动与噪声有了明显下降。

Analysis the open ditch and a single material in different forms of isolation barrier effect, and then summed up the vibration-isolation behavior of each material.
分析明沟和不同单一材料屏障形式的隔振效果，总结了每一种材料的隔振行为。
