Structural Analysis of Ladder Type Suv Chassis Frame (Diagonal Cross Bracing) using ANSYS 14.0

The vehicle chassis frame is an important part of an automobile. The chassis frame is the main structure of any vehicle. The main function of chassis frame is to support the body, different parts of an automobile and two longitudinal side members placed on it. The chassis frame has to withstand the stresses as well as deformation occurs in it and to withstand the shock, twist vibration and other stresses. The function is to carry the maximum load for all designed and operating conditions safely and it exists within a limit. On the chassis frame has maximum shear stress and deflection under maximum load. In this project, have calculated the stress (von mises) and shear stress, for the chassis frame also safety factor for safe design and the validation of design for martial, section of frame and shape on life periods will be calculated by fatigue life. Finite element analysis has been done for validation of the chassis frame model. We have taken material as Mild sheet steel for “C” Channel section, with varying the section of rectangular hollow box, “I” Section, and “O” Section to design chassis frame of an SUV. For Analysis using ANSYS 14.0. Software used in this project:-Solid work for design purpose and ANSYS 14 is used for analysis.
