DESIGN AND STATIC ANALYSIS OF MONO COMPOSITE LEAF SPRING MADE OF VARIOUS TYPES OF COMPOSITE MATERIALS USING FINITE ELEMENT METHOD

Abstract

In ithis istudy idesign iand istatic ianalysis iof imono icomposite ileaf ispring iare iperformed iin icomparison ito ithe iexisting istructural isteel ileaf ispring. iThe ibasic iidea ibehind ithis iwork iis ito ireplace ithe iexisting istructural isteel ileaf ispring iwith icomposite imaterials. iIn ithis iwork, ithree idifferent ikinds iof icomposite imaterials iare itaken isuch ias ilaminated iCarbon/Epoxy, iBoron/Aluminum, iand iCarbon/Epoxy i(Non-Laminated) iwith ithe isame ithickness, iwidth, iand iload-carrying icapacity. iThe imain iinvestigation iof ithe istudy iis ito ireduce ithe iweight iof iexisting istructural isteel ileaf ispring iwhile iupholding iits istrength. iThis istudy iseeks ito iaddress, iimproving iload-carrying icapacity, iand idesign iless istressed iand ilightweight icomposite imono ileaf ispring. iIn ithis istudy, i60% ifiber ivolume ifraction iand i40% imatrix ivolume ifraction iis itaken. iIn ipresent iwork itotal ideflection iand iequivalent ivonmisses istresses iinduced iin ithe idifferent ikinds iof icomposite ileaf ispring iare icompared iwith itotal ideflection iand iequivalent ivon-misses istresses iof istructural isteel ileaf ispring. iFor ianalysis ipurposes, iANSYS iworkbench i19.2 iis iused iand ifor imodeling iof icomposite ileaf ispring, iNX i10 i(UNIGRAPHICS) iis iused. iFinally, ifrom ithe istatic ianalysis iresults, iwe ican isay ithat ithe inewly idesigned icomposite ispring imade iof iCarbon/Epoxy i(Non-Laminated) ihas ibetter iperformance ithan ithe iexisting iconventional istructural isteel ileaf ispring
