GCON unable to solve function that include model parameters as a variable. Suggestions to run two coupled shafts with variable speed ratio?

Hi, In my model(attached) I am trying to drive a pump shaft(slave) with respect to the motor shaft(master) based on a variable efficiencies. I have coupled the two shafts using GCON.

The efficiency is calculated using the output torque and the input speed. The coupler(GCON) seems to be not working when the model parameters are used to calculate the ratio at which the pump shaft should spin. It works fine with some arbitrary generated variable that dose not involve model parameters.

Any suggestions to run two coupled shafts with variable speed ratio?

Hey Mate,

Your model works like a charm. It performs as per the requirements I had for the model. i,e Change in shaft speeds without altering the torque.

Since I am new to Adams, I have hard time understanding the energy loss in the coupling. Its kind of frustrating that I cant understand the solution and it works beautifully.

In regards to what I am trying to achieve, I would like to model a pump with volumetric inefficiencies.

Thanks for your help.

Cheers,

Ashok
