Torsional Spring
Posted: Thu May 24, 2018 8:15 am
Hi,
I want to model a torsional spring as described in https://simtk-confluence.stanford.edu/d ... bolic+Cost for the knee Joint. Could someone explain the variable Parameters: upper/lower Limit/stiffness.
If I unterstood correctly then the lower and upper Limit describe the range of Motion. If i want to model the spring for the full range of knee Motion I have to Chose -120 for the lower Limit and 10 for the upper Limit.
The lower stiffness describes the stiffness of the spring at -120 degrees and the upper stiffness describes the stiffness of the spring at 10 degrees.
So if I want the stiffness to be continuous, could I set the lower and the upper stiffness to 10Nm/degree?
Is this correct?
Thanks for your help.
