For load is destributed by the stiffnesses in a statically indeterminate structure, on the jointed-bolts at a wing root, loads are changed by the different stiffnesses, and the difference is more notable if its airfoil has a large camber. In this paper, the main structure near a new kind of ground effect aircraft s wing root is modeled using PATRAN/NASTRAN software to analyze the mechanical characteristic of this kind of connection structure. Because of the shape of airfoil, the stiffnesses at wing root are not uniform, this paper mainly investigates its effect on the load distribution of the bolts. Meanwhile, load situations of the bolts are also compared when using a central wing with stringers and without one. The regulation of bolts load distribution are given out by the finite element analysis of the local model, which is valuable for wing root connection design of similar light aircrafts.Key words: Structural analysis; Load distribution; Finite element; Camber; bolt; Airfoil; Stiffness PAGE 6 PAGE 1*倆z嘯*俧[b?{kQJ\xvzuf[/gO畫簨噀簨噀橯\O!jHr)???????????????'gd鱺 + & F凾^凾gd$+ & F劊劚^劊`劚gd$ 8則VD^則gd璿-7$則VD]^則a$gd璿- $YD2a$gd魁6$]^gd?6$勵XD2YD2]勵^gd璿-Z+f+?,J,??,...€/???f1z1?????:3X3Z3p3r3????????????蹰章挣章章章章章沾椋彛弢tphdhdhdhdh3xjh3xUhm €h$h$o($h豥h豥B*CJPJaJhph'h豥h豥B*CJPJaJho(ph!h璿-B*CJPJaJho(phh豥h豥5丆J\乤J$h豥h豥B*CJKH]乤Jph'h豥h豥B*CJKH]乤Jo(phh豥h豥CJaJo(h豥h豥CJaJ$?????????????????444444 4"4$4&464<4>4@4B4D4黧麝黧弩黧鬈黧邮梁弩弩弩弩hm €h鱺h豥h3xh€2lhF*€CJaJo(hECJo(hvCJaJo(h€2lCJaJo(h?CJaJo(h€2lmHnHu hF*€o(h豥mHnHuhF*€jhF*€U ??????444444 4"4$4$匄勱匋& #$+D﹣/劦4$a$刪]刪匄&`#$劋`劋gd€2l$劒匄勅& #$+D銆/劦]劒a$ $xぼa$$匄劽剚& #$+D銆/劦4$a$$劒勅& #$+D銆/劦^劒a$$4&4(46484:4<4>4@4B4D4 + & F凾^凾gd$ 刪刪]刪`刪 勱勬 & #$+D﹣d2別勱凧&?$+D﹣/劦 Q00&P 0p12PP/R :pE<0皟. 叭A!皀"癬#惀$悐%皀癝 惄BH@?H ck噀$1$5$a$CJKH_HmH nHsH tH^@^ h槝 1/$$$ & F>9D@&H$a$ CJKHPJh@h h槝 2=$$$ & F7$8$9D@&H$XDYDa$KHPJB@Bh槝 3 $$$ & F1@&a$F@F h槝 4$$$ & F@&a$ OJPJQJJ@J h槝 5 $$ & Fdx?@&5丆JF@F h槝 6 $$$ & Fゐ@&a$CJJ@J h槝 7 $$ & Fd@ゐ@&5丆JR@R h槝 8 $$ & Fd@ゐ@&CJOJPJQJN @N h槝 9 $$ & Fd@ゐ@& OJPJQJ$A@?$ 貫祂=刉[SOFi?F nf恏圏h :V 44 la k? 鄀Rh 8B@8 ck噀噀,ge勅WD`勅P @P u&$9r d7$8$9DH$a$ CJKHPJ4@4 u w$&dG$a$CJ4"4 槝鑜  OJPJQJJ@BJ 佽l噀,g# d8G$WD ` CJ6﨩1B6 佽l噀,g1?WD)`?@&Q@佽l_(u@CJ EHH*OJPJQJRHd0﨩b0 枡u榰 w$&da$4﨩4 CorrespondCJZ﨩Z Depart.Correspond凚劸WD?^凚`劸CJ]R﨩?R USMO$凢労WD?^凢`労a$CJ_HmH nHsH tH"W@" 亯筽5\,﨩, DateゐCJL﨩L InformationWD^`5乗乑﨩?Z Abstract$a$ CJKHPJ_HmH nHsH tHZ﨩Z Key words%剎剤?H$WD堼^剎`剤PJhB﨩B Xd亯eH$WD`PJh6﨩6 sQ.曂 劖凷DS劖`凷F﨩F R{|鱏"!WD^`PJF﨩2F Title"$$ゐ@&G$ 5丆JPJF﨩AF Name#$$ぼごa$CJOJPJRHd@﨩@ \O€$$dゐa$ CJPJRHBD﨩RD 噀MR噀,g%]^`5丳J$﨩$ 歔t&PJ2J@B2 oRh槝 '@&CJ$PJ$﨩$ hT($*$ >\鑜_(uH*F﨩F Reference*$@&G$a$5丳Jj﨩?j Text of Reference+$ & Fda$CJ_HmH nHsH tH$﨩a$ 翄f,PJn﨩?n Text of Reference 1-$ & Fda$CJ_HmH nHsH tH0﨩0 -N噀耂€噀.s.ゐ5D﨩aD 魜"/eWDXDd`PJ\\﨩\ Text of -N噀耂€噀.s%0 & FZ匎D^`匎H﨩H Text of -N噀耂€噀.s1 ZN('!( yb鑜_(uCJaJ*2* yb鑜噀W[3$a$8YB8 ZkD噀ch觺刧4-D M €T﨩RT ZkD\O€USMO駛噀T饄&5$劑劑ゐ5$9DH$]劑^劑a$CJP﨩bP f駛噀h槝&6$劑劑｜5$9DH$]劑^劑a$5丆JN﨩rN JJ<駛噀Xd亯(7$劑劑d轧5$9DH$]劑^劑a$CJT﨩T JJ<駛噀sQ.曂,8$劑劑d轧5$9DH$]劑^劑a$CJL﨩L m €簨噀ck噀9$d掐4$7$8$9DH$a$ CJOJQJ T﨩T m €\h槝1&:$d掐おお4$7$8$9DH$a$ CJOJQJ ,﨩, m €\h槝2;5丆J.﨩. m €h?Y<$a$5丆J.﨩. m €剉魦f=$a$CJZ^@Z m €nf?Q賨)>$1$5$[$\$a$CJKHOJQJ^JaJff m €Q芓€[]H$Tf^劑`刉$CJ>﨩> Qbab_cptermstyle15乗""@>Vuz#+ x2i#\3Xf i    #€€0€€€€5€€ €€€€€u€€;€€;€+€ € <0€ <0€ <0€ <0€ 0€ *0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0 €€ +0 €€ +0 €€6€60€€7€8€+0€+0€€@'0€€€葢00@'0€€€葢00@'0€€€葢00@'0€€€葢00楡0€ 楡0€ 楡0€ 楡0€ 楡0€€楡0€€楡0€ 楡0€ 楡0€ 楡0€ 楡0€€楡0€€楡0€ €楡0€ €楡0€ €楡0€ €楡0€ €楡0€ 楡0€ €楡0€ €葢00P0€€0葢0 >Vuz#+ x2i#\3Xf #0€€€0€€0€€€50€€€ 0€€€ 0€€€0€u€ 0€€€ ;0€€€;0€+€0€ €0€ €<0€ €<0€ €<0€ €<0€ €0€ € *0€€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0€€ +0 €€ +0 €€ +0 €€j00€ 0%0OZ00l毝Z00€O?€ 0$0O <?BMOR8 VZ+?D4 )?$4D4B4 $&R!?晙!?晙餒?@€€€餒 ??  饞 ??  養 S  ?"\#]#^#_l?`熵#a,?bl?
