Week 9 - Project - A pillar Design with Master Section

DESIGNING A PILLAR USING MASTER SECTION

INTRODUCTION

MASTER SECTION: Master sections development takes place during feasibility check and concept validation stages of the product life cycle. These are typically the guides for design requirements and which decides the component packaging after the development of the concept design, i.e class A surfaces.

Master section helps us to decide the feasibility of the concept design, the clearances, the packaging and the fixation strategy of a component before converting the concept design into a solid 3D engineering design.

During the period of vehicle concept design the evaluation of the master section performance depends mainly on the reference vehicle data and experience of structure design engineer.

MASTER SECTIION

REFERENCE FOR CLASS A, CLASS B & CLASS C SURFACE.

CLASS A SURFACE

check the surface quality

check the any patches available in surface with boundary

let's join the surface

TOOLING AXIS

create the two lines with the master section, bisecting the line & create the tooling axis.

DRAFT ANALAYSIS

Draft analysis for class A surface

CLASS B SURFACE

Create B surface offset form the class A surface as per master section.

missing surfaces create with swept surface.

let's join the surfaces & create the class B surface.

CLASS C SURFACE

create the surface with swept & multi section surfaces.

FINAL SURFACE

Join the surfaces without any boundary.

SIDE CORE AXIS

create side core axis using master section.

DOG HOUSE & RIBS

Create the dog house & ribs as per master section.

DOG HOUSE

Extrude the sketch convert to sloid.

to reduce the sink marks.

draft to the dog house using side core axis.

RIBS

Extrude the sketch convert to sloid.

DRAFT TO RIBS USING SIDE CORE AXIS

DOG HOUSE TOP PROFILE

GIVEN FILLETS TO THE DOG HOUSE & RIBS AS PER MASTER SECTION.
