【摘要】 本文研究了单自由度结构体系的物理参数识别方法,给出了在质量已知时对结构刚度、阻尼进行识别的计算公式.本文同时还在线性结构动力反应分析解析递推格式的基础上,研究了作用有一个外力的线性多自由度结构体系(如海洋平台导管架冬季经常受到海冰荷载冲击)的结构物理参数识别方法,给出了同时识别结构质量、刚度及阻尼矩阵的计算公式.本文所提出方法没有引入任何假定,且公式物理意义明确.文末给出了一个算例.更多还原

【Abstract】 The identification method of physical parameters of SDOM system in linear cases are researched in the paper, and the formula for identifing the rigid and damping of structure are provided when the weight is known. The physical parameter identifacation of structure of MDOF system in linear cases with a external force (for example; the pipes of ocean platform are acted by the load of ocean ice) are researched at the same time, based on the analytical recursion schemes of dynamic reaction. The paper provides the formula for identifing weight, regard and damping matrix of structure. The method have determinant physical meaning. A computing example is provided at the end of the paper.更多还原
