The orientation of the base is just [0 0 0] (Euler x-y-z) with respect to the world coordinate system.
The world coordinate system is defined as follows, when looking to the rear view of a vehicle:
x -> inside the screen/paper
y -> horizontally to the left
z -> vertically upwards
Or isn't this...
If you use the "MATLAB Function" block, you can create variables. If you name them the same you named the fields in the lookup table, these values will be put in the lookup table, no? I didn't use it so far, so I'm not sure it will work.
To measure the forces on the bearings inside a MacPherson shock absorber (strut), I built a simple test model to test the behavior. In the first model I placed the strut vertically (lower and upper mounting point exactly above each other), so the axis of operation of the joints (bearings) were...
Ok, I made some changes and now it does seem to work. But I still have a few question about the reasons:
- Shouldn't I also include the external actuation force (which actuates the body) to calculate the static friction. This one will also affect the Computed Force in the joint, no?
- Why is...
The block is indeed meant for modeling friction. I know it is possible to add kinetic friction in a more simple way by using equations. The goal is however to include stiction as well. So the model should be able to handle bot kinetic friction and static friction (stiction).
I also used that...
To test the Joint Stiction Actuator block in SimMechanics, I made a small model containing 2 bodies, a prismatic joint and a spring/damper. The actuation is a body actuator which yields a force step input after 2 seconds.
The goal is to put friction into the shock absorbers in a full vehicle...
