Designing a Car Hood – BIW Inner and Outer Panel with Hemming by given mastersections.

DESIGNING A CAR HOOD – BIW INNER PANEL AND OUTER PANEL BY GIVEN MASTERSECTIONS OBJECTIVE The main objective of this project is to design the Hood of a car that satisfies the manufacturing requirements, functional requirements. The Body in white (BIW) inner panel and outer…

INTRODUCTION

A car hood panel is the hinged cover that rests over the engine of a front-engine vehicle. Its purpose is to provide access to the engine for repair and maintenance.hood is an opening body panel that covers the engine in a front-engine veehicle. the hood is also considrered as the another type of door in a vehucle as it consists of an outer panel and inner panel.the inner panel provides strength outer panel functions as the metal cover.

A concealed latch is typically used to hold down the hood. On vehicles with an aftermarket hood and on racecars, hood pins may be used to hold down the car hood. Hoods sometimes also contain a hood scoop, wiper jets, power bulge, and/or hood ornament. Car hoods are typically constructed from steel and sometimes from aluminum. Aftermarket car hoods may be constructed from various other materials, including carbon fiber, fiberglass, or dry carbon.

DESIGN CONSIDERATIONS OF HOOD INNER PANEL

While making car hood panel we need to consiter the design consideration those are the height of the person and head reach upper limit used in japan upper limit for head zone use and europe these are considere while making the hood panel design.

SOFTWARE USED

NX CAD

DATAS TO BE USED FOR MAKING HOOD INNER PANEL

from the given data used to make the hood inner panel the thicknnes of the hood inner panel is 0.75 and outer panel is 0.75 and reinforcement thickness is 1.5 from this data hood inner and outer panel is drawn.

MASTER SECTIONS

the master section is used for making inner panel step by step processs from that process they have provided for surface distance and radius of the curveature and lenth of the deatails are provided from that masterction we design the inner panel

HEMMING

Hemming one kind of operation used in making hood inner panel from this given data used to drawn the hemming it used for wrap round the hood inner panel to improve the strenth and looks better.

RELIEF REAR SECTION ANDFRONT RELIEF SECTION

The section are used to imporve the strenth of hood inner panel is that why we are using the relief

HOOD ASSEMBLY

Finsl section hood assembly in this section we created hood inner panel and outer and provided hemming and striker and adding reinforment to assemble the part by using command of assembly constraints. the process are followed by the first is hood outer and inner panel hinges and striker and lastly used reinforcements.
