设计一种多层隔振系统用于水下爆炸试验时对电测设备的抗水下爆炸冲击防护。基于大质量法，依据计算多体动力学理论，构建空气弹簧与钢丝绳隔振器相结合的多层隔振系统的抗冲击动力学分析模型，并进行动态特性分析。结果表明设计的多层隔振系统在水下接触和近场爆炸条件下工作正常，满足试验需求；多层隔振系统对冲击载荷的缓冲效率较高，但在设计时要重点考虑系统的稳定性。

A multi-layered isolation system was designed for anti-shock protection of a electrical measurement system in underwater explosion test. Based on the large mass method and multi-body dynamic theory, the anti-shock model for dynamic analysis of multi-layered isolation system including an air spring and a wire rope isolator was built, and its dynamic characteristics were analyzed. The result shows that the multi-layered isolation system works normally in the underwater-contact and near-field explosion conditions. Its performance satisfies the needs of the test. The multi-layered isolation system has high cushioning efficiency for impact loads, but the system stability must be considered in the design.
