:o能告诉我，小气在哪了么？？

版主考虑怎样验证你的结果没有？感觉应力好大。

感谢楼主分享。
过程能运行，不过从分析问题的角度来说，咱们更应该关注结果的分析，是吧，^_^！
不知道这个结果是否正确，正如楼上所说，如何验证计算结果？
算出的最大接触压力为2173MPa,最大接触摩擦应力317.399MPa，最大接触变形为6.263um(载荷为500N吧)，不知道滚道在这种情况下是否发生了塑性变形？滚道的屈服极限是多大？滚道的许用接触应力是多少？能否应用Mises屈服判据来判定塑性变形的初始吗？

本人也刚涉入这个课题，上述问题希望仿友们一起讨论，促进共同进步。或者E-mail讨论也行：maxyhit@163.com，小马。

小弟目前也在做轴承接触问题，学习下，谢谢~~~~~~~~~~~~

好下下来
看看

i am working on dynamic simulation and experiments of main spindlebearing systems too. have already read a lot literatures abt it. andget really confused as i go further on. the kinematic behaviour ofangular ball bearings is very complex, guess i need to know more abtthe principles b4 i build a MBS FEM model of it.

ozeanluft · 发表于 2007-7-27 23:21:05

u can give me a standard bearing model number e.g B7014, and the parameters such as radial external force and geometry, lubrications, i can use my institut bearing calculation program to valiate ur result.

ozeanluft · 发表于 2007-7-27 23:24:03

i will optimize ur fem model and build up my adams model 2, looking forward to exchange some ideas

ozeanluft · 发表于 2007-7-27 23:32:24

personal opinion, the bearing kinematic model should be built in adams, with the cage and innen outer ring defined as rigid bodies, and the rolling body such as balls as flexible bodies, the lubrications will be dealt later.. then define the movement of the innenring, balls and cages. the ball has 2 rotating velocity and can be calculated with cage rotating velocity and pressing angle and so on.. the balls will be first modeled in ansys as a NMF, netrual modal file, i dont know how to do it now though, and then input this file in adams later.

still everything remains unsolved to me, pff, need to hurry up -.-!
