摘要
通过对多机系统特征值问题的摄动分析,给出了特征值与系统阻尼之间的显式表达式,得到了阻尼对多机系统机械振模正特性的数学证明。最后通过实例计算验证了理论结果的正确性。
In this paper, by means of perturbation analysis of the eigen value problem of multima-chine systems, we give the evident expression form of the relationship between the eigen value and the damping of system, and abtain the proof in mathematics of the damping positive character on mechanical oscillation of multimachine systems. Finally a computing example is given, which proves the correctness of the theory.
