Hi All,

 

i want to move a solid in a motion analysis as shown in the Picture.

Because of the resolution limitation maybe the quality of the picture is not good enough.

If you need a higher res. picture you can download it here http://dl.dropbox.com/u/1362871/Motion%20Plot.png

My Problem is the expression formulation because of the timesteps.

For the first timestep (0 - 0.55sec) its easy:

(10*((TIME/0.55)**3)-15*((TIME/0.55)**4)+6*((TIME/0.55)**5))*0.720)

 

But now i have no idea how to add the other timesteps (2-7) into the expression.

 

The only way i have found is to use the IF function. But thats a terrible solution.

 

I do not want to use the interpolated method.

 

Hopefully you can help me.

Thanks
