【摘要】 对利用光滑粒子动力学(SPH-Smoothed Particle Hydrodynamics)方法进行轮齿动态力学数值分析中的齿轮建模方法进行了研究.确定了齿轮齿根过渡曲线以及其他部分的参数方程,并根据所确定的参数方程建立了三维齿轮离散粒子模型的数学模型.编制了划分齿轮整体及局部离散粒子的SPH前处理程序.并对划分后齿轮离散粒子与齿轮理论轮廓之间进行了误差分析.分析结果表明,利用此办法可正确划分齿轮的SPH离散化粒子,是一种较好的前处理方法.更多还原

【Abstract】 The gear modeling method in dynamic mechanical analysis using SPH(Smoothed Particle Hydrodynamics)analysis is studied.The parameter equations of the transition curve of gear root and the other parts of gear are decided.The 3D discrete particles model is established based on the parameter equations.The SPH pre-process program of global and local dividing is developed.The error between the divided discrete particles and theoretical profiles of the gear has been analyzed.The analysis results show that this modeling method is a relatively better method and the correct SPH discrete particles can be divided by this method.更多还原
