I am doing an analysis on splined shaft. My aim here is to find the stresses on disc(see the attachment). The shaft transmits a torque of 4200Nm. Am facing a problem with boundary condition...any suggestions what boundary condition to use??....
what about fixing the shaft
contact between the 2 components
restraint hte disk a bit so that it doesnt' fly off (maybe in the axial direction)
apply the torque on the disk
1. if i constraint in axial alone it shows large displacement.....for torque to be applied i need to constraint the disc circumferentially(is it necessary???).. Only then software runs. else it shows model is unstable.
2. can we take Results from large displacement ??...stress values at particular location by probing??....displacement results are absurd..
let's take a step back and start simpler.
start by fixing all the teeth on your disk (eliminate the shaft) and run the analysis with your torque. see if it works. then you can start adding some complexity.
if you get the large displacement warning and choose the option "no" the results are junk. you can use them for troubleshooting your model but it needs to be run in large displacement mode or with nonlinear. to make sure your load is reasonable and your setup is ok, start by reducing the load and seeing if it solves without it.
