3.2 Simulation and Results
The simulation results are presented in Fig. 7. Two factors were evaluated namely
equivalent stress and deformation. Figure 7a shows the deformation in “Force Tuner”.
The red area (Fig. 7a) indicates the highest deformation. It is noticed that the sliding
portion faces maximum deformation as roller will be sliding on that portion when
Force Tuner is in motion, hence maximum force will be experienced by that portion
only. The maximum deformation goes only up to 0.75 mm which is under safety
