摘　　要：根据动力学原理和Lagrange乘子约束,考虑惯性载荷对螺旋锥齿轮动态啮合分析的影响,提出一种新的有限元分析模型,分析惯性载荷对螺旋锥齿轮动态啮合特性的影响规律。计算结果表明,随着惯性载荷增大,齿面接触力也随之增大;惯性载荷对于啮合区宽度、齿面接触应力及最大应力位置均有影响。因此,惯性载荷对于螺旋锥齿轮动态啮合分析是必须考虑的因素。A finite element model,in which the influence of inertial load was concerned,was introduced for the dynamic meshing analysis of spiral bevel gears based on the theory of dynamics and Lagrange multiplier constraints.The influences of inertial load on the dynamic meshing characteristics were discussed.The result shows that the bigger the inertial load,the bigger the contact force.The inertial load also affects the width of the meshing zone,the tooth contact stress and the location of maximum contact stress.These validate that the inertial load must be taken into account in the dynamic contact analysis of spiral bevel gears.
