Hi, i am a running a static simulation on this assembly. The input forces/torques are applied from the pulley shown in the image (the pulley sets on two bearings) and the aim is to get the bearing connector's reactions of all the bearings in the mechanism. There are 3 inputs, one force upward on the pulley (240 N), one torque around the axis of the shaft (-28 Nm) and one moment around axis one shown in the image (34 Nm). it is a parallelogram mechanism which is used to actuate the pronation/supination DOF of a forearm.
Now i apply the force and the torque around the axis and the results make sense and are compared to what i get by hand calculation. i face some problems to figure out how to apply the bending moment around axis one. which part of the shaft should i apply the moment on, should i put it as a torque around axis 1 or as force couple in opposite direction and where do the force act if this way.
please let me know if you need any clarification.
appreciate the help!
