Convert a joint from revolute to fix as a function of time

Convert a joint from revolute to fix as a function of time

Convert a joint from revolute to fix as a function of time

I have a part which revolutes with respect to another during operation. But since I am running a static simulation I want the joint to be initially revolute so that it comes into proper position upon applying some initial torque, and then a Fix joint, so that it can bear the load without rotating. I know that this is the wrong way, but despite several attempts, I was unable to keep it in fixed condition after certain torque, so want to keep it in a fixed condition.
So I want to know how I can convert a joint from revolute to fixed as a function of time.

RE: Convert a joint from revolute to fix as a function of time

This might work:

Put both joints into your model. DEACTIVATE the fixed joint in the ACF file. At the correct time, stop the run, DEACTIVATE the rev joint and ACTIVATE the fixed joint. Continue the run.

here's an example where I deactivate 4 sensors. This runs the sim for 40 seconds, deactivates the sensors, and runs it for a further second.


But you may have a problem with building the model with the redundant joint in. I can't remember if you can use deact in the adm file.
