Hi,
I have a model of a parallel mechanism and i want it's end-effector to perform a given trajectory, for that i've solved in maple and obtained three lists of 121 values for the motion of each leg of the mechanism.
In ADAMS i created 3 splines: x=0,1,2,..,120 that represents the time, and y = the lists i've mentioned. Then i used this splines with the following syntax
AKISPL(time,0,SPLINE_1)
And i choosed StepSize=1 but didn't obtain good results. The trajectory i want is a circle in the XZ plane, but the one obtained from the simulation is not on the XZ plane and it is not a circumference, although it is a closed curve.
Can anyone help me?
Thank you.
