循环式行星滚柱丝杠副作为行星滚柱丝杠副的衍生机构,是一种通过多个沟槽状滚柱与丝杠、螺母螺纹啮合的传动机构。为了研究循环式行星滚柱丝杠副的随机振动疲劳特性,文中基于疲劳失效理论,建立了该传动机构的有限元模型,并进行了动力学分析和疲劳寿命预测。首先,根据材料应力-循环寿命(S-N)曲线和Miner线性疲劳累积损伤理论,利用疲劳分析软件对循环式行星滚柱丝杠副进行疲劳分析,得到了接触区域的疲劳结果云图和各节点的损伤值;然后,基于建立的4种疲劳寿命预测模型,将得到的解析解与仿真损伤值进行对比。结果表明:循环式行星滚柱丝杠副在3 960 Hz下引发的共振对其结构造成的损伤最大;循环式行星滚柱丝杠副在相同激励频率条件下的最大接触应力和最小疲劳寿命的区域相同;循环式行星滚柱丝杠副谐响应分析应力峰值和疲劳分析功率谱密度峰值的对应频率相同。该研究可为循环式行星滚柱丝杠副设计与抗疲劳优化提供理论指导。

The recirculating planetary roller screw mechanism, as a derivative of planetary roller screw mechanism, is a transmission mechanism that is engaged by the screw or nut thread and multiple circular groove rollers. To study the random vibration fatigue characteristics of the recirculating planetary roller screw mechanism, this paper established a finite element model of the mechanism based on fatigue failure theory, and conducted the dynamic analysis and fatigue life prediction. Firstly, according to the material stress-number of cycles (S-N) curve and Miner’s linear damage accumulation theory, fatigue analysis was carried out on the recirculating planetary roller screw mechanism using the related software, and fatigue results in the contact area and damage values at each node were obtained. Then, based on the developed four fatigue life prediction models, the obtained analytical solutions were compared with the simulated damage values. The results show that the resonance induced by the recirculating planetary roller screw mechanism at 3 960 Hz causes the most damage to the mechanism. When the excitation frequency is the same, the area of maximum contact stress and minimum fatigue life is the same. Besides, the corresponding frequencies of the peak stress in the harmonic response analysis and that of the peak power spectral density in the fatigue analysis of the recirculating planetary roller screw mechanism are the same. This study can provide a theoretical guidance for the design and fatigue optimization of the recirculating planetary roller screw mechanism.
