Possible error in the reaction force due to the simulation of contact between two bodies
I think I have an error on the calculation of the reaction force due to the contact between two bodies.
As you can see from the figures I have a conical pin inserted in a special slot. At the end of the pin there is a fixed support, while at the end of the slot there is a point mass that simulates the weight of a shaft and what is mounted on it. This shaft is supported at both ends by two conical pins (in the simulation I considered only one pin, halving the weight of the mass to be supported).
The contact constraint was assigned as follows:
- type of contact = friction
- conical pin = contact
- slot = target
- friction coeff = 0.7 (steel vs steel)
- behavior = symmetric
At this point, by checking the reaction force, I get that all the weight (2700 N) has been discharged in the Z direction. But shouldn't there also be a substantial thrust component in the Y direction?
I have also attached my hand calculations, so as to show you my reasoning.
Do you think there is an error in the hand calculations or is the FEM modeling to be wrong?
