车床滚珠丝杠进给系统中，由于加工和装配误差的存在，其几何参数的随机性对系统的动态特性和车削精度有很大影响。在这项研究中，提出了一种新的集中动力学模型占的解析分段恢复力函数涉及的整体轴向变形。对包含名义接触角变化的轴承接头等效力学模型进行了合理简化，便于获得系统的解析运动方程。此外，所提出的方程的近似解析解的修正Lindstedt-Poincaré方法（MLP）获得。采用改进的一次二阶矩法（AFOSM）对动态响应误差进行可靠性评估。最后，通过数值模拟验证了MLP和AFOSM方法在实际应用中的性能。最后，讨论了外激励、滑台位置和名义接触角对动态响应的影响，并根据实际车削精度水平进行了可靠性和灵敏度分析。
For ball screw feed system on a lathe, the randomness of geometric parameters deriving from the inevitable manufacturing and assembly errors significantly affected the system dynamic characteristics and turning accuracy. In this study, a novel lumped dynamic model accounting for the analytical piecewise restoring force function involving the overall axial deformation is proposed. The equivalent mechanical model of bearing joints including the change of nominal contact angle is made a reasonable simplification to facilitate acquisition of the system analytical equation of motion. Additionally, the approximate analytical solution of the proposed equation is obtained by the modified Lindstedt–Poincaré method (MLP). The advanced first order second moment method (AFOSM) is employed to evaluate the reliability of dynamic response error. Furthermore, the numerical simulation aims to demonstrate the capabilities of the MLP and AFOSM method in the practical applications. Eventually, the effects of external excitation, sliding platform position, and nominal contact angles on the dynamic response are discussed and the reliability and sensitivity analysis in accordance with actual turning accuracy level is presented.
