I. INTRODUCTION

In head-on collisions of bonnet-type cars (sedans, wagons, hatchbacks, etc., here after referred to simply as cars) and heavy trucks, the car often under runs the front of the truck, and the car crew received the serious or fatal injuries. The crash safety performance of the car depends on the way its structural parts interact with the structural parts of the truck. FUPD equipment that prevents the car from under running the truck is obligatory in India. The required strength and ground clearance of FUPDs are specified in the relevant regulations used in India. Accidents between cars and trucks are among the most fatal accidents because of the car under running. This phenomenon leads to serious and fatal injuries for car occupants because of intrusion of the car structure into the passenger compartment. . .

IV. Conclusion

1. Head on collision contribute significant amount of serious accidents due to lack of FUPD in heavy trucks.

2. As per Indian standard IS 14812:2005 regulation the Front Under-run Protection Device is designed using Nx8.0 software and analysed by commercial finite element software and found satisfactory results.

3. The maximum displacement, Von mises stresses and strains under impact load of FUPD bar in different cases are studied to meet the requirements as per IS 14812:2005, and this results are to be compared with experimental results.

4. With the above used CAE tools we can reduce the time and increase the productivity of the design and avoid the costly experimental testing.

5. As per above three results second model is safe, strength and low weight model.

6. We can suggest to automobile industries to keep this type of FUPD to car, gypsy, truck, busses…Etc. which saves the life of passenger with less injury.
