KMOR是Krylov Model Order Reduction的简称，下面是一个简单的介绍。7 E w' h& B$ p- Z' e

Contributions of eigen modes with resonance frequencies much higher than the maximum frequency are negligible，only need low frequqncy modes& }, Y$ V% g7 l: H$ N0 X

KMOR is one order of magnitude faster than the commonly used interpolating frequency sweep. j0 o, Q4 {6 O/ e
