摘　　要：为研究变双曲圆弧齿线圆柱齿轮动态接触特性,利用基于旋转刀盘加工原理得到的齿面方程,运用MATLAB与UG建立精确的齿轮三维模型,运用ANSYS LS-DYNA分析得到该齿轮齿面在啮合过程中的动态接触应力。通过研究不同齿线半径变双曲圆弧齿线圆柱齿轮的动态接触应力,得到齿线半径对该齿轮动态啮合特性的影响规律。通过研究不同压力角变双曲圆弧齿线圆柱齿轮的动态接触应力,得到压力角对该齿轮动态啮合特性的影响规律。通过研究不同载荷下该齿轮的动态接触应力,得到载荷对该齿轮动态啮合特性的影响规律。分析结果为变双曲圆弧齿线圆柱齿轮的设计及工程应用提供参考。In order to study the dynamic contact performance of cylindrical gear with variational hyperbola and circular-arc-tooth-trace,based on the tooth surface equation obtained from the machining principle of rotary cutter,a precise 3D model of gear can be established by using MATLAB and UG.The distribution of contact stress in the gear tooth surface during the meshing process is obtained by ANSYS LS-DYNA.By studying the dynamic contact performance of cylindrical gear with variational hyperbola and circular-arc-tooth-trace under different radius of the tooth line,the influence of the radius of the tooth line on the meshing performance of the gear is obtained.By studying the dynamic contact characteristics of cylindrical gear with variational hyperbola and circular-arc-tooth-trace under different pressure angles,the influence of pressure angle on the dynamic meshing characteristics of the gear is obtained.By studying the dynamic contact stress of the gear under different loads,the influence of load on the dynamic meshing characteristics of the gear is obtained.The analysis results provide reference for the design and engineering application of cylindrical gear with variational hyperbola and circular-arc-tooth-trace.
