IV. R esult and D iscussion The A and B results on the NPT were analyzed using a finite element method. The deformation behavior was examined based on the Von Mises stress distribution on the NPT. Figure 5 shows the contour of the Von Mises stress on loading A, indicating that the NPT is deformed in the direction of the load. The maximum Von Mises stress position appears in the middle column supporting the loading condition, as noted in [24], due to stress concentration focused on one elbow. The value of Von Mises stress in all loading A models appears to have increased compared to the validation model, as reported in [21], where the weight supported by the tire in the validation model, which is equivalent to 800 kg, becomes a variation of weights with values between 480-530 kilogramsor equal to 4700- 5200N. The increase in the value of Von Mises stress is in the range of 39-53% from the original value of 4.759 MPa to 6.62 MPa to 7.31 MPa, as reported in [17] and [18](Figure 6). Figure 5: The Contour of Von Mises Stress on Loading A Figure 6: Graph of Von Mises Stress on Loading A The results show that loading B on the NPT results in a deformation contour similar to loading A, as shown in Figure 7. Increasing the value of G in the loading B model causes a significant increase in the Von Mises stress value. Comparing the stress value in B1 with the validation model reveals a decrease of 9.5% from the original value of 4.759 MPa to 4.35 MPa, as reported by [17] and [18]. In contrast, the stress value in B2 to B5 increases by 7% to 53%, as reported in [21] (Figure 8).
