Optimization and Parametric Analysis of Under Run Protection Devices for Heavy Commercial Vehicle

  According to the report on accidental statistical data, about 1214 road crashes occur every day on road, which takes a- bout 17 lives on an average every hour. About 54. 1 per cent of persons killed in road accidents were in the 15-34 years age group during the last year. Trucks and buses are involved in about 70%of fatal crashes in both rural and urban areas with under running of smaller ve- hicles like passenger cars. Therefore design of under run protection device plays an important role in safety of partner vehicle. Also emis- sion norms are becoming stringent day by day and limiting greenhouse gases emissions like CO2 mainly depends upon fuel economy and hence on overall gross weight of vehicle. Combined weight of Underrun protection devices like RUPD(Rear Underrun Protection De- vice), SUPD(Side Underrun Protection Device)and FUPD(Front Underrun Protection Device)makes larger part of gross vehicle weight of heavy commercial vehicles. The objective of this work is to design and optimize under run protection devices RUPD, FUPD & SUPD for commercial vehicle which satisfy safety recruitments of standards. Various beam cross sections with different parameters such as beam thickness, support bracket thickness and support inclination angles are considered. Modelling of under run protection devices is done in CREO 2. 0 tool and simulation carried out by using ANSYS 15 software package. Results show the optimum strength with reduc- tion of weight and cost of underrun protection devices.
