Modeling

  • How to model a subject wearing active actuator

 

  • Sample models

Optimization process

  • CMC procedure contains static optimization process

...

Assign large value of maximum force to each actuator to reduce the size of xactuator, so that the influence of actuator to J is diminished.

  • CMC procedure contains static optimization process

Cost function of optimization process in CMC (Slow target)

When there is active actuators on OpenSim Model, the activation term in cost function becomes

 

 

 

 

 

 

Fact = Factmax * xactuator

Assign large value of maximum force to each actuator to reduce the size of xactuator, so that the influence of actuator to J is diminished.
