摘　　要：某电子设备在工作过程中承受振动和冲击等动载荷环境,其动态响应过大而导致电气特性下将,无法满足使用要求,因此对其进行阻尼减振设计。结果表明,经处理后电子设备的振动减振效率大于55%,冲击加速度放大倍数小于1.6,有效改善了电子设备的工作环境。Electric equipment suffers dynamic load such as vibration and shock at work, as a result, failing to work normally as the response exceeded its tolerance, thus the damping design was applied to reduce vibration and ab-sorb shock. Tests results show that vibration reduction efficiency is larger than 55 percent, magnification of shock re-sponse is less than 1.6, and the work environment of electric equipment is improved efficiently.
