The dynamic model of an asymmetric defects on an angular contact ball bearing raceway has not been fully described before. An advanced 10-degree-of-freedom dynamic model that includes detailed contact forms between a three-dimensional cubic-like defect and balls is proposed in this article. Examples are load distributions, ball passing defect profiles, varying effective stiffness between balls and raceways, and the impulse response caused by the collision of balls and defect edges. The results suggest that the circumferential size of the 3-D defect has a significant effect on the contact force distribution, which consequently generates impulse vibration in the bearing system. The analysis on the axial and circumferential sizes of defect show that the extension of the defect in the circumferential direction should be avoided. Additionally, the reduction of the radial-axial load ratio could mitigate the vibration impulses.

角接触球轴承滚道上不对称缺陷的动力学模型以前没有得到充分描述。本文提出了一种先进的十自由度动力学模型，该模型包含了三维立方缺陷与焊球之间的详细接触形式。例如负载分布，滚珠通过缺陷轮廓，滚珠与滚道之间的有效刚度变化以及由滚珠与缺陷边缘的碰撞引起的脉冲响应。结果表明，3-D缺陷的圆周尺寸对接触力分布有很大影响，因此会在轴承系统中产生脉冲振动。对缺陷的轴向和周向尺寸的分析表明，应避免缺陷在周向上的扩展。此外，
