Week 6- Challenge

AIM: evaluate quality critera of the hood component.

OBJECTIVE: below mentioned quality criteria of the hood with using hypermesh

TARGET ELEMENT LENTH 5mm

S.N	Quality Criteria
1	Aspect Ratio
2	Skewness
3	Warping
4	Taper
5	Min. Length
6	Max. Length
7	Min angle Quad
8	Max angle Quad
9	Min angle Tria
10	Max angle Tria
10	Tria %

PROCEDURE:

1. import the elelment in step file
2. go to preferencec and give all mentioned dimencions than apply on the compnent .with on the hing part only remainig all in swith of mode
3. extract the mid surface of the hing
4. and also autocleanup of the mid surface of hing.
5. then doing mesh of t6he mid surface of the hing
6. using quality index and find the errors with using tools and doing quality mesh of the hing
7. after than find the edges with using edges tool
8. than combine the elements and clear the edges problemm

9.than reflect the hing .go tool option select element click on displayed and dublicated the current component select the nodes and base points than hing reflection done.

10.after the hing reflection switch of the hing and switch on the latch .remaining all switch of the component.

11.than midsurfacing of the latch.autoclean the latch

12.meshing the latch and clear the drag elements .incase formed any dublicate elementd than will remove dublicate elements and create the new elements on that place

13 after finish the proper mesh you i would get quality mesh and find the edges and clear the all dublicated and clear the errors

14.after finish the latch .switch ofg the all and switch on outer component .toggle the lines and create new line convinently for doing meshing

15.doing mid surface of tbhe outer hood. and divide into two equal parts and cut the one the part of outer wood and will create a middle line on anglar hood and than doing mesh of the outer wood

16.finsh the proper mesh and remove unvanted nodes and elements than will get a quality mesh after completion of the meshing reflect the outer hood component same as hing.

17.go to tool and select elements than displayed and click on dublicate slect the nodes and base ponits than reflect the outer hood

18.after finish the outer wood and will go to inner hood

19. toggle the lines in this component switch of the hinges and mid surface of the inner hood and doing mesh of inner hood

20.after inner hood mid surface .divided in to two equal parts and deleate the one part of inner hood. and than doing mesh and remove unvanted nodes before meshing .because the small nodes creates big problem while doing mesh.

21.delete the dublicate components carefully.and create new elements . after finish the meshing mesh reflect the inner hood .go tool and select the elemets and clic on dublicate than reflect the inner hood.

RESULT:

figure: inner hood mid surface

fig:mid surface of then hinges and latche

figure: mid surface of the outer wood
