Hood design-Week 2

Designing of hood assembly :

we have to design the hood assembly the with respective parts like striker and hinge assembly and hemming process by the following steps .the following steps explained along with the images and explained below

Designing of inner panel :

1st we have to do the offset from the given outer panel and we have to draw the 5 flanges by using sketch after drawing the sketch we have to project the sketch on the inner panel byusing project curve .After the projection done we have to do emboss with certain thick on the inner panel.The reason for the emboss is provide extra strength for hood .after that we have to make cutout on the emboss that we have done already .The cutout is used for the pedestraions safety while crashing time .If the emboss are there with out cutout it will make huge injury to the pedestrions.but with cutout the hood take damages and make less injury to humans .The image of the inner panel with emboss and cutout is attached below .

The inner panel has to be thicken 0.75 mm thicknees on outer side

Hinge assembly :

The hinge assembly we need to fix in the 2 corners of inner panel . For fixing hinge assembly we need flat surface with valid thickness in the inner panel .we can fix the hinge by using touch constraints and parallel constraints .After constraints are done we can fix hinge in hinge mounting.one side of hood we can fix it other side we can create with mirror assembly . The image of hing with mounting is attached below .

Striker :

The striker fix in the top of the inner hood by using trajectory striker .the image of trakjectory sketch is attached below .

After completing the trajectory we need to fix the striker with intersection constraints .after that we need to extract the rear surface of the striker to create the striker mounting .after extraction we need extend the sheet and with law extentsion we created the striker mounting .edge blend should be provided with minimum dimension

The strike with mounting image iss attacehd below

Hemming :

Hemming is the procces of connecting the outer panel with the inner pannel with the certion gap distance between inner outer panel .

we create hemming by offseting the outer panel and trimming the sheet by using trim sheet command .after these steps are done we need to creat the surface by using law extension between the offset surface and outer panel afte r that we can make three face blend the sheet are get connected each other . we have to provide hem releves for at the edge of 4 corner the image is attached below . the outer panel has to thicken about 0.75mm thickness on the inner side . After completing above all process we can unhide the inner panel ,stiker ,hinge assembly ,outer panel assembled.

the images are attached below
