Modal Analysis Of A Stepped Bar Using Matlab & Ansys

摘要

Man, starting from the age of civilization, wanted to simplify the processes which he felt difficult while working out in a routine way. Now we are living in the world of technology. We have different fields of study. Engineering is one among such professions which provides students the caliber to deal with the problems in a different way. Almost all the problems of various subjects which we deal in our mechanical engineering have solutions. Finite Element Methods is a subject where we deal with the elements but not the entire body at once. But still it involves a lot of calculations like Matrix multiplications, solving higher order equations etc. We have chosen a topic in Finite Element Methods i.e. Modal Analysis of elements and are working out to get results in a simpler way. In this paper we use MATLAB software to simplify the tiresome calculations involved in Modal Analysis of Stepped bar. The code for solving the problem chosen was written in Mat lab and was tested for different inputs. Even though it is accurate and has a large number of built in functions, it is lagging applications in most of the mechanical fields. The code and the procedure we are presenting here in our paper don't exist. The program written asks the user for inputs and gives output after making necessary calculations. Finally we are also using ANSYS 11.0 workbench software for verifying the results obtained in the mat lab
