摘　　要：以新型破茬圆盘刀—倾斜波纹圆盘刀为研究对象,基于Pro/E建模仿真软件,建立了三维模型;进行了圆盘上点运动学分析和运动轨迹动态仿真;验证了影响切割破茬质量的两大因素—波纹倾斜角θ和波纹数z的设计值θ=33°和z=40是合理的;并且对波纹圆盘刀进行了应力分析,确定了最大应力的部位和应力值。运动学仿真和应力分析的结果验证了倾斜波纹圆盘刀设计的合理性和可靠性。This paper takes a new type of disc coulter with oblique ripple as a research object. First, a three - dimensional model by Pro/E was established, and kinematic analysis of the points on the disc coulter was made. Second, dynamic path curve was simulated and two important key parameters were validated： ripple obliquity （θ） and number（ z）, θ=33°and z = 40 are optimum. Third, static stress analyses was made, the maximum stress and location are ascertained. According to dynamic simulation and stress analyses, the design of disc coulter with oblique ripple is optimum and sicher.
