VibrationSimulationUsingMATLABandANSYS_muya
转载:众所周知有限元解决振动问题的能力还是有限的, 比如做齿轮啮合过程的动力学模拟就要同时涉及到接触和动力反映两个主要方面. 目前处理此类问题最成熟的软件当属MSC.ADAMS, 但ADAMS也只能在模拟过程中做到弹性与刚性接触而已! 据我所知, 已不止两位研究生试图用LS-DYNA来做此类模拟, 他们忽略了(或没搞清楚) LS-DYNA只能处理瞬态问题, 而对于该过程的模拟也是无能为力的!!! 结果是浪费了大量的时间, 甚至机会. 这本应是导师的责任, 但许多高龄导师对现代软件的不熟悉也是....那么此类问题的具体解决方案在哪里? Vibration Simulation Using Matlab and ANSYS 给出了答案. 掌握书中的内容意义非同小可! 这对于要从事CAE工作的将会受益(起码在今后20年内).随着我国经济的高速发展 解决资本积累必将是要遇到的问题, 工程(设备)维护, 系统监测也将(象发达国家)成为CAE非常重要的部分. 早早入手就能使你立于不败之地!(This book has three main purposes. The first purpose is to cc..-ct in one
document the various methods of constructing and representing dynamic
mechanical models. The second purpose is to help the reader develop a strong
understanding of the modal analysis technique, where the total response of a
system can be constructed by combinations of individual modes of vibration.
The third purpose is to show how to take the results of large finite element
models and reduce the size of the model (model reduction), extracting lower
order state space models for use in MATLAB.)
