| Abstract: | The software of machine tool structure Modal Analysis and Optimal Design (MAOD) can be applied to the analysis and optimization of dynamic mechanical characteristics on a microcomputer. The inputs of the software are excitation and response signals from testing. The main modules of MAOD include identification of modal parameter, animated display of complex mode, senstivity analysis, structural modification and optimization of structural parameters, etc. The principle of the main modules is described briefly, then the examples of application of MAOD to a frame structure and two machining centers are given in this paper. |
