I need to simulate a typical hydraulic crane-arm with
MDO.
I use a path and slot-connection to simulate a desired
movement of the arm and I use a table as input for servo-
motor input on the slot-connection. So far so good in
static-analysis which gives me the position of each
cylinder in time.
Now I want to measure the force on each cylinder in time,
so I run a dynamic analysis with gravity.
After a while I found out that the servo-motor
automatically uses a spline-fit Interpolation instead of
linear fit, though the settings are still the same.
Whats going on?
ps. I find it amazing that there are no really good
tutorials available for MDO, they are all so superficial,
if any..!
