摘要

摘要: 对汽车玻璃升降器中塑料导向轮的蠕变变形进行研究,基于材料的蠕变拉伸试验曲线,采用修正的时间硬化蠕变方程,并考虑绳轮接触影响,建立导向轮的蠕变有限元分析模型。计算获得了导向轮关键位置的应变、位移时间历程曲线及其变化规律,对比试验结果,吻合良好。分析接触情况对蠕变的影响,并与不考虑接触情况下的蠕变过程进行对比研究。结果表明:考虑接触的蠕变分析计算结果精度相对较高,能够反映出导向轮的形变和应力变化过程。

Abstract: The creep deformation of plastic guide wheel in auto glass lifter is investigated in this paper. Based onthe material creep tensile testing curve and the modified time hardening creep equation, the finite element model ofguide wheel creep analysis is established considering the contact effect of rope and wheel. Though numericalcomputation, the time history curves and their variation laws of strain, displacement at the guiding wheel keypositions are obtained, and these well agree with the test results. Analysis results both considering the contact effectof creep process and not considering the contact condition of creep process are compared. The results show that thecalculation results considering the contact creep analysis has relatively high precision and can reflect thedeformation and the stress of the guide wheel change process.
