摘要 研究当多源激励浮筏隔振系统中存在材料非线性刚度和分段线性刚度时系统的功率流,用灵敏度分析方法研究系统多源激励浮筏隔振系统功率流对于材料非线性刚度和分段线性刚度参数的灵敏度。研究系统功率流对这些参数的敏感程度,估计参数变化的效果,从而指导系统结构的优化。 The powerflow characteristics of the multi-source excitation of the floating raft system are studied in the case that there exist material non-linear stiffness and piecewise linear stiffness in the system. The sensitivity of the powerflow to the material non-linearity and piecewise linearity is analyzed utilizing the mobility powerflow analysis method. The result is of significance for the system optimization.
