Week 11 - Final project

KKunapuli Sai Teja14 Jan 2023

AIM:

To design and development of vehicle interior door trim using Catia V5 with given class A surface along with Master section. Also create the Side Attachment features as per design rules.

OBJECTIVE:

To create thickened part using master section for reference
To create the mounting features as per design guidelines in the industry and with master sections
To perform Draft analysis & Tooling analysis

INTRODUCTION:

The door panel is the interface between the interior of the car and the inner workings of the door. Generally the door panel is divided into parts for easy designing like arm rest, map pocket, lower substrate. These require one of the toughest requirement among the interior parts of the car. This should be designed to with stand the load while being less than 2mm in thickness and also to protect the occupants during collisions.

Door currently have an inner full width panel consisting of electronic windows, central locking system and speakers. These panels typically consists of a foamed core covered with either textiles or plastics.

Parts:

1. MAP POCKET

2. BOTTOM SUBSTRACT

3. PUSH_PIN_CLIP

4. ARM REST

5. BOTTLE HOLDER

ARM REST:

The Final part will create in following steps:

STEP - 1 CREATING TOOLING AXIS:

Tooling axis and draft analysis are explained below for arm rest.

tooling axis will be created by following steps.

tooling axis can be created in three different method.

they are: 1. X,Y,Z axis 2. Normal to the surface 3.Bisecting method.

here I used Normal to the surface method.

first extacted the surface and a point created as shown below.

afterr a line taken normal to the surface as shown below.

STEP -2 CREATING B-SURFACE:

first the A- surface will be offset upto the thickness of the part 2.5mm

some parts like fillets, complex shapes won't be offset due to it's fillets radius and their shape.

so, using join command we will remove shapes and extrapolate and then trim.

STEP - 3 CREATING C - SURFACE:

using A-Surface edges, we will create c surfaces.

STEP 4 FINAL PART BODY:

now we will join and trim A,B,C Surfaces.

using close command we will create close body.

STEP 5 DRAFT ANALYSIS FOR FINAL BODY:

MAP POCKET ANALYSIS:

BOTTOM SUBSTRACT ANALYSIS:

BOTTLE HOLDER ANALYSIS:

CREATING ENGINEERING FEATURES:

DOG HOUSE CREATION:

Extracting the surfaces of the part to create dog house.

Procedure to create dog house on LOWER SUBSTRATE:

Step 1: Create a point on required location and a plane from it. Create a sketch with base sketch for dog house.

Step 2: Use sweep tool to create a surface using this profile and draft direction at a draft angle of 1.5 degrees

Step 3: Use extrapolate and extrude option to create required surfaces and use trim and split to obtain the outer body of dog house.

Step 4: Create a new body and name it as dog house. Use thick surface option to create a solid of required thickness.

Step 5: Translate the dog house to required height using translate option and use thick command to extend the base surface to intersect the lower substrate.

Step 6: Extract the inner base edge and create a surface to get the required base profile. Use thick surface to create a solid and use Boolean operation to remove it from the base of dog house.

Step 7: To create top profile for attachment of push pins, create a sketch, extrude it and split it from the solid using split option

geometrical set for creating DOG HOUSE shown below.
