Lukas, When using ChLinkBushing, you need to access the various individual ChLinkForce objects, using ChLinkLock::GetForceX(), ChLinkLock::GetForceY(), etc. (see https://api.projectchrono.org/classchrono_1_1_ch_link_lock.html ) and then invoke the GetF() method on each one (see https://api.projectchrono.org/classchrono_1_1_ch_link_force.html). I realize that this is a bit too convoluted, so I will add a ChLinkBushing functions to directly return the bushing force and torque. As a side note, ChLinkBushing is implemented as a “free” joint with internal forces on the 6 DOFs, so it is no surprise that Get_react_force() returns all zeros (there are no constraints).
For ChLoadBodyBodyBushingGeneric, use ChLoadBodyBody::GetForce() and ChLoadBodyBody::GetTorque() (see https://api.projectchrono.org/classchrono_1_1_ch_load_body_body.html). --Radu From: [email protected] <[email protected]> On Behalf Of Lukas K Sent: Tuesday, June 27, 2023 12:37 AM To: ProjectChrono <[email protected]> Subject: [chrono] Bushing reaction forces What is the way to get reaction forces from bushing for: 1.
