摘要

球面滚珠联轴器是沙滩清洁车垃圾拾取装置液压马达与拨沙滚轮关键联接装置。为研究拨沙滚轮球面滚珠联轴器的疲劳寿命,首先,运用点接触的L-P理论对其进行了寿命计算;然后,运用有限元法建立了联轴器的数值分析模型,通过增广拉格朗日算法对其进行多体接触有限元分析,利用ADAMS中的Impact函数进行运动学分析得到滚珠的接触载荷谱;通过Fatigue Tool软件根据Miner法则进行疲劳寿命分析。结果表明,疲劳寿命的有限元计算结果与理论计算结果比较吻合,球面滚珠联轴器满足设计要求,证明了理论计算的合理性。为联轴器的疲劳寿命研究和后期的优化分析提供了参考依据。

Abstract

The spherical cylinder coupling is the key connection device between sand roller and hydraulic motor of beach- cleaner. To study the fatigue life of spherical cylinder coupling of sand roller,firstly,the fatigue calculation with L- P theory of point connection carried out,the numerical analysis model of coupling with finite element method is built and the multi- body contact finite element analysis with augmented Lagrange algorithm is completed. Then,the cylinder load spectrum is obtained through kinematics analysis with Impact function in ADAMS. The fatigue life is analyzed based on the Miner theory in Fatigue Tool. The results demonstrate that the finite element calculation is consistent with theoretical calculation. The spherical cylinder coupling can satisfy the design requirements. The result proved the rationality of theoretical calculation. A basis for other coupling fatigue life research and simulation in the later is provided.
