results in an increase in the stress value by 0.74 MPa, as described in [24]. Figure 7: The Contour of Von Mises Stress on Loading B Figure 8: Graph of Von Mises stress on loading B The results indicate that loading A and B produce a similar deformation contour. However, the stress value on the spokes with loading A increases less steeply than with loading B. This is because packing A only involves a 50 kg increase in passenger weight, equivalent to 2.6% of the vehicle weight. At the same time, loading B has an independent deceleration variable where a rise of 0.1G has a value of 12.5%. To compare the variables that affect loading A and B, the forces acting on the tire are calculated and presented in Table 3. The data in the table show that the detail working on the tire is much higher in loading B than in loading A. The deceleration variable in loading B is the primary cause of the higher forces. The values in Table 3 also reveal that the vertical load on the tire is higher in loading B, as is the friction force, which is a function of the coefficient of friction between the tire and the road surface. Based on the data in Table 3, it can be seen that loading B has a more significant effect on the NPT than loading A due to the higher forces acting on the tire. These forces, in turn, lead to higher levels of Von Mises stress in the spokes. The difference in stress values between the two loadings highlights the need for further research to explore the effects of different types of loads on the NPT. 4.35 5.09 5.83 6.57 7.31 2.00 3.00 4.00 5.00 6.00 7.00 8.00 B1 B2 B3 B4 B5 Von Mises (MPa) Von Mises B © 2023 Global Journals Global Journal of Researches in Engineering Volume XxXIII Issue II Version I 18 Year 2023 ( ) G Investigating the Effects of Load and Deceleration on Non-Pneumatic Tire Deformation and Stress during Braking
