Design and Analysis of A Truck Chassis Frame

1. The finite element analysis of Truck Chassis Frame is carried out using 10 noded brick element. The static and Modal analysis is carried out. 2. The Static analysis has a significant effect on the overall stresses in the Chassis Frame. 3. By using Stainless steel and Duralumin materials Static and modal analysis was done to see stress and mode shapes of structure. 4. By comparing Results of Stainless Steel and Duralumin. Finally we can say Duralumin is better than Structural Steel. MATERIAL DEFORMATION(mm) STRESS (Mpa) Factor of safety STRUCTURAL STEEL 1.71 58.491 4.2 DURALUMIN 4.76 58.1 7.7 5. Chassis designed now is capable of withstanding to the loads up to 18 tones with minimum weight by using Duralumin. 6 . From tabular column Duralumin is better than Structural Steel. 7. . From the above table it can be understandable that though the deformation is more for . duralumin it is more stronger due to its higher factor of safety. 8. As Duralumin is a light weight material the weight of the chassis decreases and therefore . the vehicle efficiency increases.
