Automotive Door Design Structural,Optimization of Front Door for Commercial. Vehicle with ULSAB Concept for Cost and,Weight Reduction. Mr Sandeep Bundele Dr Mrs Rupa S Bindu, Abstract This research papers describes the drawbacks of which is not costly and recyclable Lightweight steel can. existing automotive door structure and suggest design be achieved by improving the performance of the. changes to overcome the present drawbacks This research. structure or adopting new manufacturing techniques 25. paper details out the analysis of the existing structure and. identifies the drawbacks and explains the process of door One of the efforts is the ULSAB ultra light steel. system design Changes required can be found out with autobody concept ULSAB suggests three main weight. Global Journal of Researches in Engineering B Volume XII Issue II Version I. correct method as explained in this paper Validation of the reduction techniques such as hydro forming and the. design parameters is of vital importance so the way by which tailor welded blank TWB In this research the TWB. validation of newly designed or modified parts can be done is technique is utilized for lightweight door design and a. briefly explained in this paper Designer from an automobile design process is proposed for optimizing the. engineer faces so many different problems during their work automobile TWB door In the automotive door assembly. Some of the major problems in automobile door are taken as door inner panel is divided into different thickness. problem for this research paper and those problems like high. without reinforcement components and different, weight high cost excessive reinforcements and water. leakage At first theoretically study of the existing system is thickness sheets plates are assembled by laser. done After that deciding the key areas of modification is the welding The use of tailored steel solutions eliminates. flow of this paper After finding the modification areas we tried the need for additional reinforcements and overlapping. some parameters for calculation On the basis of calculations joints in the body saving material and further reducing. the design of new parts are finalized Then 3D models are total weight In this way tailored blanks are a significant. prepared in CATIA V5 which are used for analysis purpose enabler to meet specified CO2 targets Reducing the. Finally on the basis of analysis results actual metal parts are weight of a car reduces CO2 emissions Objective of. developed in the proto shop and fitment trials are taken on the this paper is Low cost door design for developing. vehicle Once the fitment trial is completed actual testing is. countries India Srilanka South Africa without, done on the vehicle Comparing those results with the old.
results the improvement is suggested during this study some compromising any performance and regulatory. specific parameters are chosen for observation and requirements for example removing molded trim with. improvement On the basis of these results final design is hard pad cost saving approximately 1400 Rs set. frizzed Reducing the weight of door assembly by reducing. Keywords ULSAB Concept Problems in TWB number of components and by using advance. technology new inner panel for hardpad water leakage technologies like tailor welded blank and high strength. issue material Existing design has a water leakage problem. from the assembly of inner door panel and seal because. I Introduction of different thickness of inner panel The parts which are. ecently there have been two approaches in newly designed or modified are designed on the basis. reducing automobile weight One is by using of space constrained The main constrained is that. material lighter than steel and the other is by avoids as much as modification in the machined parts. redesigning the steel structure Although the, former seems very effective it is very expensive so that it. may only be used for an expensive automobile, Therefore the automobile industry is trying to use steel.
