Applying point force load to head
Posted: Sat Mar 09, 2024 5:15 am
Anyone please clarify.
My experiment is applying load to four points of the head and doing roll, pitch, and yaw activities.
I have the force magnitudes vx vy and vz and the point position px py px (marker position).
So on the external force mot file, I filled in the vx, vy, and vz-magnitude values, and for the positions px, py, and pz, I filled in the marker position values.
My Doubts:
1. Is it the right way to apply a load to the head through a marker point attached to the skull?
2. Is torque necessary or not for the application of point force?
3: After applying the load, the green external forces are not visible; they are seen inside the skull. Does this affect the analysis result?
4. My model is a half-body model. Do I need ground-reaction external forces for my model?
5. The static optimization-muscle force result of with load and without load diff is very small. Any comments on this?
