摘要
探究了含三维裂纹斜齿轮应力强度因子及J积分在不同初始裂纹参数条件下的数值曲线分布规律。运用有限元软件对含初始裂纹的斜齿轮进行了数值分析,模拟求解齿根椭圆形裂纹尖端3种类型的应力强度因子及J积分,分析了3种应力强度因子与J积分随裂纹长度、裂纹角度、裂纹位子等初始裂纹参数的变化规律。研究表明,改变不同的初始裂纹参数数据时,所的对应的3种应力强度因子与J积分的曲线图有着很明显的变化规律。
The distribution of stress intensity factor and J integral of helical gear with three-dimensional crack under different initial crack parameters is studied.The finite element software is used to analyze the helical gear with initial crack.Three types of stress intensity factors and J integral at the elliptical crack tip of the dedendum are simulated and solved.The variation of the three stress intensity factors and J integral with the crack length,crack angle,crack position and other initial crack parameters is analyzed.The results show that when the data of different initial crack parameters are changed,the curves of the corresponding three stress intensity factors and J integral have obvious changing rules.
