【摘要】 本文较系统地研究了圆柱齿轮传动系统的动态特性，在齿轮系统动力学基本理论体系和WfMC提供的工作流参考模型的基础上，研究开发了一套基于工作流管理方式的齿轮动态特性分析平台软件。论文的主要内容包括： 在.NET环境下用C#设计开发了一套单实例的工作流管理系统，完成了工作流引擎系统、用户分析计算平台和过程定义编辑器的设计与开发。 依据典型的齿轮传动系统动态特性分析内容，设计开发了一套用于齿轮传动系统动态特性分析的执行器。 使用本文研究开发的齿轮传动系统动态特性分析平台，以TJ^**发动机减速器为原型，将齿轮系统动力学分析和齿轮动强度分析相结合，详细分析了单自由度齿轮传动系统的动态特性。 以WJ^*改型发动机减速器为原型，建立了考虑传动系统中所有零件分离的动力学模型，详细分析了封闭行星传动系统的动力学性能，并得到了相关的结论，得到的结果可直接用于系统中各零件的动强度分析。 本文研究开发的齿轮系统动态特性分析平台较好的将齿轮系统动力学和齿轮动强度分析相结合，实践表明，该分析平台可以灵活方便的完成齿轮系统动态特性分析的相关计算任务。更多还原

【Abstract】 In this dissertation the dynamic behaviors of cylindrical gear system have been systematically studied. Based on the basic system info of gear system dynamics, and the workflow reference model provided by WfMC, a software platform that can be used for the dynamic behavior analysis of gear systems has been researched and developed. The research works are listed as follow:A workflow management system that can be run in the .NET framework has been designed and developed. The system includes the workflow engine, the analysis workbench and the process definition tool.Based on the typical works of gear system dynamic behavior analysis, a set of executors that can be run in the workflow management system have been designed and developed.Taking the gear system in the TJ* * engine as prototype, the coupling effects of the gear system dynamics and the gear structural dynamics on the analysis of the gear system is taking into account.A torsional-lateral coupling dynamic model with every part separated is proposed to predict the dynamic behaviors of encased differential gear train. The model takes the gear system in the WJ* aeroengine as prototype. The dynamic characteristics of the model have been analyzed in detail, and the system dynamics results can be used for the structural dynamics analysis of every part.The software platform developed in this dissertation combines the analysis of gear system dynamics and the analysis of gear structural dynamics together. The simulations of the platform prove that it can be fit for the analysis tasks.更多还原
