    Friction force estimation

    waiting for suggestions

    Friction force estimation

    Dear All, @Prakash Pagadala in attached image green- housing yellow - shaft blue- ball ball makes a contact with shaft at 2 points and with housing at 2 points. at every contact there is an interference of 3 microns. housing is fixed and shaft is allowed to translate axially. i tried contact with static coefficient of friction and and clearance value but still groove surface of shaft and housing is penetrating the ball and vice versa. can anyone suggest how can i work on this??

    contact definition

    Dear Prakash, please suggest any corrections.

    contact definition

    dear all, i have defined S2S contact with static coefficient of friction 0.1. roller edge is penetrating inner ring edge. how can i resolve this issue.

    Distortion due to heat treatment

    Dear @Prakash Pagadala any updates ??

    Distortion due to heat treatment

    Dear Prakash, we manufacture our cylindrical component (tube) by forming process. After all stages of forming we are having 20-30 microns of ovality (accepted band). When we are doing heat treatment on the same, we are getting ovality in high amount. So the concern is, can we simulate this phenomenon using FEA? We are interested in capturing distortion due to HT cycle and optimize the same. @Prakash Pagadala

    Contact analysis

    These are in contact, Outer ring of bearing is press fitted into the housing with the above mentioned interference value. as per physics, housing should expand and outer ring should contact. here outer ring is getting contracted and creating gap between housing and outer ring as i showed above in Image 2. my question is why it is showing gap?, outer ring should touch housing inner surface.

    Contact analysis

    geometry is with tolerances, these parts are in interference fit (image1) of 80 microns, I used clearence of -0.090. but after completion of simulation it is showing gap like in image 2

    Contact analysis

    If I have interference, What should i use clearance or search distance?

    Contact analysis

    Dear @Prakash Pagadala, @Nachiket Kadu Suppose case 1: I have an interference of 80 microns in shaft and housing and case 2: if i have gap of 80 micron bet same. how can i define frictional contact contact between above cases. can you revert with when to define search distance and when to define clearance. also, how to choose track

    Contact analysis

    Dear Nachiket, Thanks for support, Issue was of equivalence. I forgot to do the same. Now it is sorted out.

    Dear All, how can i resolve this error.?

    Fatigue Analysis

    Dear All, Can we do assembly level fatigue analysis? I want to do Fatigue analysis of bearing assembly. If yes, Please provide the sample tutorial of fatigue analysis at assembly level.

    Hoop stress prediction

    Dear @Prakash Pagadala Should I need to impose my constraints and loading in same co-ordinate system?? or should i keep same?

    Hoop stress prediction

    Is there any stress conversion matrix for cylindrical to Cartesian coordinate system???
