Preload force / Correct gear movement _ MSC ADAMS

Preload force / Correct gear movement _ MSC ADAMS

Preload force / Correct gear movement _ MSC ADAMS

(OP)
Hello everyone again :) I need help with two things ponder

1) Which function I can simulate the preload force "Fw" as in the figure below?


2)This is what the normal simulation of a gear belt looks like? I mean these oscillations marked with a blue arrow, I used the dimensions of the standard "ISO 5294".

Oh, just in case, SFORCE is what you are looking for in the expression builder)


I mean the preload function force "Fw" which stretches the belt, for example push 100N and not come back like the green block on the move below. I checked the "SFORCE" documentation but I don't understand how to use this function for this example.

RE: Preload force / Correct gear movement _ MSC ADAMS

You have to write an expression for a force between the two parts the pulleys are mounted to that pushes them apart. it'll look something like SFORCE/2901761,I=290761,J=0100,TRANSLATION,FUNCTION=150000, except with different i and j markers

Hmmmm, "SFORCE/2901761,I=290761,J=0100,TRANSLATION,FUNCTION=150000" This formula describes the same as applying that force from menu selection?

under the skin, yes. You'd may need 2 bodies, not one.)


If SFORCE formula is the same as force from the selection menu button and I apply it, the green box still makes a move



I mean the preload effect when you tensioning the belt and turn the screw (push the green box for example 100N and fix it), as below video
