Need help with simulation issues
Posted: Thu Jun 01, 2017 7:12 pm
Hello 
,
I am trying to study the effect of acceleration on the vehicle occupant. For this purpose I am using a modified version of Raabefullbody model. I have modeled the occupant seat as an half space and I have restricted its motion in a specific direction using slider joint with the ground. I have also added a seatbelt and prescribed sufficient force on it. I plan to study the effect of passive and active muscles in detail. I have three issues with my work currently:
1. The simulation runs fine with satisfactory motion until 0.3 seconds but beyond this the simulation crashes or gets stuck. I could'nt identify the solution of this.
2. I also need help with identifying the suitable muscle properties such as optimal force, slack length etc. to be defined in muscle properties.
I have attached my .osim file to this message.
Your insight will be helpful.
