Hello<\/p>\n

I think I have an error on the calculation of the reaction force due to the contact between two bodies.<\/p>\n

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).<\/p>\n

The contact constraint was assigned as follows:<\/p>\n

– type of contact = friction<\/p>\n

– conical pin = contact<\/p>\n

– slot = target<\/p>\n

– friction coeff = 0.7 (steel vs steel)<\/p>\n

– behavior = symmetric<\/p>\n

<\/p>\n<\/p>\n

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?<\/p>\n

I have also attached my hand calculations, so as to show you my reasoning.<\/p>\n

Do you think there is an error in the hand calculations or is the FEM modeling to be wrong?<\/p>\n
