Hi, 

I am simulating a linear oscillating machine. My problem is how can I simulate movement of the machine during whole period. Whole period means movement in z-axis in one direction then in opposite direction. 

Now I do it that I simulate one direction with half period of AC current, then I do it again in opposite direction with second period of current. Not only does this take a long time, and I have to do figures in 3rd-order software, but there is a possibility that the results in the second direction are not correct. 

Is there a way to make the direction change automatic, or to set exact values of the movement in the transient simulation? 

I want to get results like this. Force in motion in both directions. The motion is not symmetrical. 

I will be thankfull for any input.

Hello,

You can use mechanical transient, or use a function of time as speed, or use a dataset pwl(dataset,time) as speed.

Thank you, I did it through the dataset. Working really well, exactly what I needed. Thanks.
