Abstract - In our society mobility conditions are adding
Analysis (FEA) software and life security of the users can be guaranteed.
drastically with growing population and contemporaneously environmental perceptivity is also adding. Thus it's making a big challenge for transport pots of government and private drivers to manage vehicles and business policy makers to handle them. Accordingly, the light and heavy passenger vehicle manufacturers as well as vehicle body builders have to borrow new request conditions along with minimal introductory safety of the passenger.
1.1 Problem Description In MSRTC workshop nearly 2000 number of bus are manufactured per year. The periodic conditioning of these buses will be done after every three years or after running every three lack kilometres. In most of the cases it was observed that failure occurs at joints at clits or pillars, as we can see in figure 1 & 2. So there will be requirement for the replacement of the failed members to recondition. This replacement of components is very time consuming and tedious job. These buses are designed to survive at least a minimum of ten lack kilometres. Therefore high strength designs, materials and components must be used.
The design includes detailed design, development and analysis of the body structure of machine. According to AIS law, performance parameters have to be followed by the machine body builders to insure needed strength. To insure strength of the machine body, all the machine body builders have to assay their design in any one of the FEA( Finite Element Analysis) tool. With the help of FEA tool bone can gain accurate results of strength of design in lower time. As notified in Rule number 126 of the CMVR 1989, all machine body builders have to use anyone of the FEA tools by themselves or with authorised test agencies to corroborate the strength. Key Words: Bus Body Structure, FEA, Strength Improvement, Vehicle Body Builders
1. INTRODUCTION All the OE vehicle manufacture sells their vehicles in drive away chassis forms, so that customer can get vehicle body buildings don as per his requirements and choice with local body builders with low cost. These local body builders use low quality parts and materials in a poorly designed body which leads to accident some time later. These body structures are not safe since designs are not optimal, for example these designs provide more heat transfer, noise, and vibrations inside the cabin.

1.2 Objectives of the project Demand for public transport is increasing day by day. To ensure strength of the newly innovatively designed component, it has to be tested and analysed. These are the objectives of the project
All the automobile body builders have a big demand for compact body and can accommodate more number of passengers with good safety of all the passengers. Therefore these new body designs must have high strength to withstand more load of increasing passengers. The strength of body is analysed and verified through the Finite Element
