Hood design-Week 2

OBJECTIVE : Design hood outer panel, inner panel and required reinforcements with the given master section and design parameters in UG NX.

COMPONENTS

1.Hood outer panel:

2.Hood inner panel:

3.Hinge and Striker:

Latch Trajectory:

Circle is drawn from the centre of hinge axis to finalize the position of latch and striker. For proper mating the tip of the striker should be tangential to the latch trajectory.

Emboss Definations:

Embosses are provided to increase the strength of the hood. shape and size of the embosses also determines the direction of the force distrubution resulted from frontal collision. Therefore the shape of the embosses should be designed in such a way that the collision forces should be directed away from the passengers ie. towards the hinges.

HEMMING:

Hemming is a forming process in which the edges of the sheet are folded over another part with the help of rollers in order to achieve a tight fit.

Corner relief for hemming:

Mastic data:

Mastic sealants are elastic components that behave like rubber and are used to stick the outer panel and inner panel. It is applied between the inner and outer panels at specified spots as shown below. Each spot of mastic sealants has its effect around a circular region of 80 mm deaimeter.

FINAL ASSEMBLY :
