A product data management Framework for the design and Development of headlamps for Passenger cars

Abstract

Passenger car manufacturers often outsource the design and newlinedevelopment of functionally critical components Headlamp is one of such newlineunits posing challenges to the designer owing to the functional requirements newlineon visibility and styling preferences of customers A supplier may not have newlinepowerful product data management PDM product lifecycle management newline PLM systems as in the case of OEMs Instead the use of domain specific newlinecomputer aided design CAD computer aided manufacturing CAM newlinesoftware is expected with the suppliers The suppliers of headlamps are to be newlinesupported with adequate information on changes in style of the vehicle in newlinesuch a way that supplier can participate in the product development process newlineThis work is motivated by such a background and tries to provide a newlinesolution that can be used as a basic framework for the development of newlineheadlamps A systematic design methodology incorporating high level newlineaesthetics and regulatory requirements was proposed in the first part of this newlinework The methodology enables the designer to address customer newlinerequirements using coherent computer aided design CAD platforms newlineDevelopment of the critical components in headlamp assembly namely lens newlineand reflector are focussed The present trend of passenger car styling is the newlineuse of headlamp with totally integrated exteriors with the car body The newlinedesign methodology provides automatic generation of exterior surface newlinematching with the profiles of car body The design module for reflector helps newlinegenerate tailored reflector in compliance with the standard illumination of newlineroads The second part of this work is development of product model newlinesupporting co designers and users of the downstream phases of product newlinedevelopment The multiple views developed in this work are in parameter newlineperspectives Product development groups involved create knowledge on newlineselected attributes of the product from several functional perspectives This newlineprocess is highly iterative and the information models used for product newlinedevelopment have to provide consistent and manageable solutions That is newlinethe knowledge available from upstream function is transferred to the downstream newlineteams for further processing This leads to the concept of view as newlinepractised in industry and hence the relevance of multiple view information newlinemodels newline newline
