摘　　要：研究了斜盘发动机的隔振技术。分别对发动机惯性力与惯性力矩、线性振动响应进行了分析,并用多尺度方法研究了钢索滞后非线性隔振器的软弹簧幅频特性,给出定性分析与计算结果,为详细的隔振技术试验与产品设计奠定了分析基础。研究结果对降低筒形发动机激励下水中兵器机械噪声,提高自导性能有重要应用价值。The vibration isolation technology for a wobble plate engine is researched. The inertia vibration isolator, whose stiffness shows hysteretic characteristic. Qualitative analysis and calculation results are given, which become the analysis base for detailed experiment and design of vibration isolation technology. These conclusions are of great practical significance in both reducing the mechanism noise excited by truck engines and enhancing the performance of homing system in underwater vehicle.
