本文首先对机械结构的动力修正作简要的说明。接着介绍了机械结构动力修正方法中所涉及的几个理论问题,即摄动修正法、修正中的灵敏度分析、按共振规范进行修正以及用试验数据改进有限元计算的可信度等。然后从三个方面介绍有关结构动力修正的软件,并利用一框图简要说明利用计算机辅助技术干预机械产品设计的主要过程。 In this paper, the mechanical structure of the dynamic correction for a brief description. Then, several theoretical problems involved in the dynamic correction of mechanical structure are introduced, that is, perturbation correction method, sensitivity analysis in correction, correction according to resonance specification and improvement of the credibility of finite element calculation with experimental data. Then, the software of structural dynamic correction is introduced from three aspects and a block diagram is used to briefly illustrate the main process of using computer-aided technology to intervene mechanical product design.
