Ground Reacted Force Calculation
Posted: Fri Nov 29, 2024 1:15 am
Hello, may I ask how ground reaction forces are calculated in Scone? I am building a model based on the OpenSim human body model (simplifying the foot as two circles located at the heel and toe, with a radius of 0.03), and inputting joint data obtained from Scone simulation into this model. I am calculating the ground reaction forces based on the Hunt-Crossley Force (https://simbody.github.io/3.7.0/classSi ... Force.html). The normal forces are consistent, but the friction force I calculated is always positive, which is inconsistent with the Scone simulation. I believe I must have made a mistake somewhere. Could you explain how Scone calculates the friction force?Thank you.
