knuckle simulation

I am doing a component level analysis where I don't have knuckle assembly. I just have knuckle. I have doubts regarding SPC. Should I apply spc on caliper mounts on knuckle? Also  there are four bolt connecting knuckle with the dust cover. Should I constrain those or just constrain the suspension mounts?

    Hi Alekh,

     

    I presume you don't have the caliper mount component and the Knuckle would sit on this caliber.

     

    if yes, you can constrain the nodes of the Kunckle which sits on the mounts using SPCs

     

    The better way to model the bolts in the assembly is to tighten them by pretensioning analysis.

     

    You can apply bolt pretension in OptiStruct and make the cover come into contact. Else, you can just define a FREEZE type of contact between the cover and bolt head

     

    Let is know if you need any further information 

     

    Thanks,

    Sir I don't have any other component except knuckle so, I cannot define contact so should I apply spc on calliper mounts on knuckle and also on dust cover mount on knuckle?

    Yes, please constrain them using SPCs
