Abstract
The car body structure fatigue damage is mainly caused by the vehicle dynamic response, which is usually expressed as stress or strain time history. Stress/Strain calculations for fatigue life estimation can be performed in the time domain or Frequency domain. The detail car body stress analyses with ANSYS were performed based on 3Dlsdyna and mode analysis is also performed here. Modal analysis is usually used to determine the natural frequencies and mode shapes of car body structure.Vibration and Crash Analysis of Car Body using Ansys is carried out and including dynamic, static, crash analysis and so on. The main objective of the project is to find fundamental characteristics like frequency, stress and displacement for different material and velocity influence in the car body structure. If the fundamental frequency is increased beyond our designable value, if possible engineering changes can be made in the car body structure. In the car body structure the factor of safety value may be a half of the factor of safety of the existing material. Car body design can be modeled by using Pro-Engineer modelling software. Analysis can be analysed by using Ansys and 3DLSDYNA
