Abstract: Project is aimed at finding the characteristics of mode (and vibrational) responses of heavy vehicle chassis at particular frequency inputs. The chassis dimensions are taken from an automobile workshop ,is developed in pro-E media and has been imported to ANSYS commercial software to perform the modal analysis. Modal analysis determines the vibration characteristics (natural frequencies and mode shapes) of a structure or a machine component during free vibration. The natural frequency and mode shapes are important parameters in the modal analysis of any component. Given suitable conditions with some excited input (frequency), mode shapes are obtained.We followed block lanzcos method in modal analysis. By analysing the mode shapes,we can able to detect the defects in the component.So changing the natural frequency or other parameters can fix the damage. So, using the ‘Modal Analysis’ feature of ANSYS we come to know of the mode shapes and their changes according to the frequencies. This is the way we get to know of unwanted vibrations and eliminate by further respective processes.In this paper we have shown only mode shapes and their results,in the next step we will do the analysis of mode shapes.
