摘　　要：为了更准确地获得刨头刨削过程的动态性能,考虑三维间隙的影响,采用虚拟样机技术建立了刨头-中部槽滑架体的三维接触模型;采用非线性弹簧阻尼接触力模型,以刨头实验载荷为激励对模型进行仿真研究。研究结果表明:刨削深度、刨削速度影响刨头与滑架体的碰撞力均值及各接触面的碰撞次数;在一定范围内,随着刨削深度、刨削速度的增大,刨头与滑架体的碰撞力均值减小。研究结果为刨头的结构优化设计提供理论依据。In order to obtain more accurate dynamic performance of planing process,considering the effect of three-dimensional gap,the three-dimensional contact model of plow head-slide frame was established by virtual prototyping technology.The contact farce was adopted by a nonlinear elastic-damper mode.The model simulation was performed by taking the roller experimental load as the stimulus.The results show that the mean value of impact force of plow head and slide frame body and the collision times of each contact surface are influenced by plow depth and plow speed.In a certain range,with the increase of the plow depth and plow speed,the mean value of collision force between plow head and slide frame body is reduced.The research results provide a theoretical basis for the structural optimization design of plow head.
