Аннотация: A two-step model order reduction method is investigated in order to overcome problems of certain one-step methods. Not only optimal combinations of one-step reductions are considered but also the selection of a suitable intermediate dimension is described. Several automated selection methods are presented and their application tested on a gear box model. The implementation is realized using a Matlab-based Software "MORPACK". Several recommendations are given towards the selection of a suitable intermediate dimension, and problems in Model Order Reduction combination are pointed out. A pseudo two-step is suggested to reduce the full system without any modal information. A new node selection approach is proposed to enhance the SEREP approximation of the system's response for small reduced representations.

Therefore, it is reasonable to sacrifice with model accuracy in order to obtain a simpler model. It is recommended to reduce the order of system model while keeping the dominant behavior of the original system. This low-order model... | 33510 тг |
