Hood design-Week 2

BUTTERFLY VALVE:  It fits between two pipes and function has opening and closing valve of the pipe with the lever.  Here we used the bottom up assembly , which mean created individual part of the butterfly valve separately and then add them to the assembly. ISOMERIC VIEW: FRONT VIEW: SIDE VIEW: TOP VIEW: 2D DRAWING…

DEVELOPMENT OF DOOR TRIM PANEL: The aim of the project is to create a thickened part with reference to master section and create attachments features on the B side following the engineering design standards industry guidelines.  In this project we create door trim inner pannel consists of : Arm rest Map pocket Bottle…

MASTER SECTION:  In simple terms master sections are the sketches of the solid component, designing a 3d CAD model will take adequate time period so to skip the wait we create the sketches for the desired component to check with assembly, positioning and gap and flushness. It is also called as master sketches , this…

HEAT STAKES:  As the assembly engineering features like dog house , ribs and screw boss the heat stakes also created for the support in assemble the products. Heat staking is the process of heating a plastic material to join thermoplastic material with thermoplastic component or any other dissimilar metal in manufacturing…

DOG HOUSE:   Dog house is designed on the class B surafce to give additional support to the screw boss over 100mm length, to restrict the action of sink marks on the class A surface by providing minimal length at the base, in case of design a screw boss perpendicular to the tooling axis. DRAFT ANALYSIS:  Draft…

RIB:    Ribs are created to provide additional strength and stiffenes to the solid model without affecting the thickness of the product. In addition to that in some designs ribs are also used as stoppers. Design considerations on Rib: Draft need to be 0.5 deg Height of the rib 5 times the thickness (t)of the…

BUMPER:        It is the front component of the car body, which protects the radiator fan & shroud and interior engine room components. It is made of plastic. It consists of the position for radiator grille and head lamp mountings. DRAFT ANALYSIS:       Draft analysis is done to check…

 DRAFT ANALYSIS:        To ensure the moulded product to eject from the core without damage on the sliding walls, darft is used.        Draft is defined as taper angle or draft angle of certain degree given to the core and cavity. If consider the walls of core & cavity be…

DRAFT :    When a design a product with core and cavity method, the one important aspect we need to ensure is the draft.  Draft is nothing but the taper angle or draft angle given to the core cavity model. This is done because if the model is straight and perpendicular to the core then while ejecting the…

ASSEMBLY WORKBENCH:    In assembly workbench we assemble the separate part files into a singlr product file. STEPS TO BE FOLLOWED:    First we need to create a solid model of each child parts of the component     Then we have assemble all the child parts in the assembly workbench MODEL…

BACK DOOR :             The back door of the car protects the rear portion of the car as well as covers the boot space, and it also said to be " tail gate ". In the back door there will be the glass window for rear vision, and also tail lamp, indicator light, stop light will be located…

ROOF:      Roof of the car is one of the most important component .It plays a major role during the roll over of a car in an accident for the safety of the passengers. so it is must to provide the greater strength to the roof and its components. As the roof outer surface needs to pass HDC and SLC conditions…

FENDER :          In cars the portion over the wheel is the fender. In early days most of car used full bumper model it costs more materials and as well as more weight to the car. So inorder to reduce the cost of material and scrap management now a days we go with half bumper models in fender  …

Fender wheel arch :                In short terms, it protects / houses the wheel and prevent from throwing stones,mud and miscelleneous particles on the road into the car body / to another car / to the pedestarin walking aside.               To ensure the wheel arch sfaety there are three standards followed according…

SECTION MODULUS : In general terms it refers to the strength of the object/part. The section modulus of the part increases it also increases the momentum of resistance of the part / object. So in order to increase te strength of a part we need to increase the section modulus. Formula to calculate section modulus:  …

HOOD PANEL:       Hood is the part which covers the face of the car body , and it covers the engine components and battery. It is the most important and preventive part of the car body. the surface and strucrure of the hood acts a major role in piercing the car into the wind. there components of the…

Under-Body coating It gives a special layer of coating on the bottom of the chasis frame to prevent it from corrosion and other  occuring damages.Most of the car manufacturers are doing it ,consider as the safety aspect.It is also called as anti-rust coating. Types of Under Body Coating: Paint spray/dipping Rubber…

Bench marking- It deals with identify and compare a product/part with its parental model/competitor to implement new features. To compare the product we have to make a carryover study on both our product/part and our competitor product/part.It leads us to make a better change to our product in the market. Now let we see…
