9.3 Finite Element Analysis
9.3.1 Model Selection
Once a free body analysis was carried out on the motor mounts, two
main forces needed to be analyzed: the simulator weight force and the
motor spin torque. These forces have been illustrated in Figure 53.
What this meant was that we would need to simulate in ANSYS the
main face of the motor mount having both these types of forces acting
on the bearing holes at the same time.
To simulate the forces, bearing loads were placed at each of the holes
splitting the weight of the simulator (Figure 54a) and added four other
bearing loads separately to depict the torque acting upon the bearing
holes (Figure 54b). To fix the motor mount, the bearing holes on the
bottom side of the plate were fixed, as these were to be attached to the
simulator base (Figure 54c). These do not experience as much force as
the main face of the motor mounts so their analysis was unnecessary.
