An issue of OpenSim ID analysis need help
Posted: Tue Sep 15, 2015 9:55 am
Thanks a lot for reading this topic. Recently, I simplified Gait_2354 model into a five link model and try to make inverse dynamical analysis to get driving torques needed for each joints. I try to get angular velocity and angular acceleration by "w=(Theta(i)-Theta(i-1))/(Time(i)-Time(i-1)); a=(w(i)-w(i-1))/(Time(i)-Time(i-1))", but the results generated large noises.
I found that angular velocity and angular acceleration generated by "Analysis Module" both are very smooth. Could you please tell me the OpenSim and Simbody's method of generating corresponding angular velocity and angular acceleration by joint angles? Are there special filter methods used?
Thanks a lot. I am looking forward to your reply.
Best,
Xiangjie
