0引言 本文研究速度和位移系数矩阵为奇异阵的线性集中参数系统反问题的另一解法。集中参数非保守系统的振动反问题,是由系统的特征值和特征向量(称其为谱数据),求解出与质量、阻尼和刚度参数相对应的系数矩阵。一般地说,由已知系统的谱数据并不能唯 0 INTRODUCTION In this paper, we study another solution to the inverse problem of the linear lumped parameter system of singular arrays with velocity and displacement coefficient matrices. The inverse problem of the oscillating parameter non-conservative system is the eigenvalue and eigenvector of the system (called spectral data), and the coefficient matrix corresponding to the mass, damping, and stiffness parameters is solved. In general, the spectrum data of a known system cannot
