German standard VDI2230 bawuti yolumikizana pamwamba ma modeling njira ndi zomwe highway guardrail bawuti mbale guardrail bawuti bawuti zambiri

olt olowa pamwamba ndi mtundu wa mawonekedwe olumikizira omwe amagwiritsidwa ntchito pamakina, amakhala ndi chikoka chofunikira pamayendedwe osasunthika komanso osinthika a zitsulo zosapanga dzimbiri wononga makina. Muchitsanzo cha chimango cha mota, cholumikizira cha bawuti chimakhala pakati pa chivundikiro chakumapeto kwa mota ndi silinda, komanso pakati pa silinda ndi maziko.

Chifukwa chake, pepalali limatenga gawo lamoto ngati chinthu chophunzirira momwe nkhope yolumikizirana ya bawuti imayendera pamayendedwe amagalimoto ndi njira yofananira ya nkhope ya bawuti. Monga chipangizo chamagetsi wamba, kuchuluka kwa phokoso la mota kwakhala chimodzi mwazofunikira zoyezera mtundu. Papepalali, mota yolowetsa 75kW imatengedwa ngati chinthu chofufuzira, ndipo kugwedezeka ndi phokoso la mota zimanenedweratu pophatikiza ANSYS ndi SYSNOISE. Ntchito zofufuzira zapadera ndi izi: (1) kudzera mukuwunikanso zolemba zoyenera, kutenga chimango chamoto monga chinthu chofufuzira, njira yoyeserera yoyeserera ya chimango chamoto, idaphunzira magawo osiyanasiyana a bawuti olumikizana pamwamba (kuwongolera koyambira kosiyanasiyana kukakamiza ndi roughness pamwamba, njira zosiyanasiyana processing pamwamba, osiyana bawuti nambala) chikoka cha zida zamagetsi ndi malamulo boma. (2) zosiyanasiyana bawuti olowa pamwamba ma modeling njira anatengera kukhazikitsa maziko a malire chinthu chitsanzo, kayeseleledwe kayeseleledwe ka galimoto chimango mode, ndi poyerekeza ndi zotsatira experimental, ndipo amaika patsogolo mtundu zochokera German muyezo VDI2230 bawuti olowa pamwamba. njira yachitsanzo, ndikutsimikizira kuti njirayo ndi yosavuta komanso yotheka yopangira ma bawuti olowa pamwamba, kusanthula kwazinthu zomalizidwa kuyala maziko a mota wotsatira. (3) Tengani 75kW induction motor monga chinthu, gwiritsani ntchito Pro/E kukhazikitsa 3d yolimba yamotoyo (kuphatikiza stator, nyumba, kutsogolo ndi kumbuyo kumbuyo), ndikugwiritsa ntchito njira yopangira bawuti yolumikizirana pamwamba potengera Chijeremani. muyezo wa VDI2230 kuti akhazikitse mtundu wocheperako wa mota, ndikuwunika modal ya mota. (4) Unikani mpweya gap flux kachulukidwe kachulukidwe kachulukidwe kagalimoto kamene kagawo ka rotor kokwanira ndi 60/50, ndikuwerengera ma radial electromagnetic excitation ya motor stator potengera izo. Yankho lachidule la chimango chamoto linawunikidwa, ndipo kuyankha kwa vibration kunapezedwa, komwe kunafanizidwa ndi zotsatira zoyesera kuti zitsimikizire kulondola kwa zotsatira zowerengedwa.
(5) Chitsanzo cha malire a chimango chamoto chimakhazikitsidwa pogwiritsa ntchito Hypermesh. Kuthamanga kwa liwiro la node yamtundu wa motor frame mu domeni yanthawi kumasinthidwa kukhala data yothamanga pama frequency domain polemba ANSYS spectrum analysis program ya stainless steel chemical nangula. Kuwerengera kwaphokoso koyezera kwa mota kumachitika pogwiritsa ntchito pulogalamu ya SYSNOISE, ndipo gawo lamawu owunikira amawunikidwa.
Mbiri ya bawuti ya Highway guardrail ya Guardrail bawuti
Guardrail bawuti mbale ndi chingwe alonda zonse ndi zinthu zoteteza mumsewu waukulu, palibe chotetezera chimodzi pamsewu waukulu, guardrail bolt mbale splicing bawuti chitsanzo ayenera kuphatikiza awiri kuteteza bwino yosalala ndi chitetezo cha mseu waukulu. Kodi ma cable guardrail bolt plates ali ndi vuto? Pankhani yolowa mumsika, idalephera kupikisana ndi opanga ma bawuti ambiri azitsulo mbale

Kenako, tiyeni tiphunzire za ubwino ndi kuipa kwa mbale yothamanga kwambiri ya guardrail bawuti ndi chingwe guardrail bawuti Mbali zodzitetezera: chingwe guardrail ndi mpanda bawuti mbale kugunda mbale mulingo kupewa ali ndi mlingo wake wa chitetezo: A, B, S, koma chingwe guardrail Kuteteza kwa bolt ndikwabwinoko kuposa mbale ya guardrail bolt, chingwe cha guardrail bolt chingwe chimapangidwa ndi zingwe zingapo zachitsulo, zingwe zamawaya zopewera kugunda komanso kulimba mtima ndizolimba kwambiri. Komabe, kupanga bawuti mbale ya chingwe guardrail n'kovuta, ndipo n'kovuta kukonza kuwonongeka kwa ndime mapeto, choncho si koyenera kugwiritsidwa ntchito mu kagawo kakang'ono utali wozungulira pamapindikira. Panthawi imodzimodziyo, imakhala yosawoneka bwino ndipo kutalika kwaufupi sikuli ndalama.
Guardrail bawuti mbale imakhala ndi malata zitsulo mbale, guardrail bawuti mbale mbale, malata mtengo guardrail bawuti gulu mapeto akhoza kuyamwa mphamvu ya galimoto, koma kutha kudzipulumutsa yekha ndi osauka, pambuyo mphamvu ya guardrail bawuti mbale ayenera kusinthidwa. 0(Mtundu A kodi :F-1)200*200*3
Kukana dzimbiri: Pali mitundu yambiri ya njira zoletsa kuwononga ziboliboli za chingwe cha guardrail ndi mbale ya guardrail bawuti, koma kwenikweni zimakhala pambuyo pa chithandizo cha dip chotenthetsera. The anticorrosive zotsatira za otentha dip galvanizing mankhwala ndi wangwiro kwambiri. Chifukwa chake, zotsutsana ndi dzimbiri zazinthu ziwiri zoteteza misewu yayikulu ndizabwino kwambiri.
Kuyerekeza kulimba kwa mzati: pali mitundu yambiri yamagawo a guardrail bolt plate, omwe amatha kusankhidwa malinga ndi zosowa zamainjiniya. Chingwe cha guardrail bolt makulidwe ang'onoang'ono, koma makulidwe ake ndi makulidwe ake mwachiwonekere ndizabwino kuposa gawo la guardrail bolt plate. Good luso processing, ntchito odana ndi dzimbiri kuviika kupopera mbewu mankhwalawa zotayidwa, nthaka kuviika kupopera mbewu mankhwalawa nthawi zambiri amakwaniritsa zotsatira zabwino ndithu, kutalikitsa moyo utumiki wa bawuti mbale ya khwalala ngozi guardrail.
Chifukwa chake, kulimba kwake ndikwabwinoko kuposa gawo la mbale ya guardrail. Kukonza: kuchuluka kwa ma bolts a chingwe guardrail ndi kochepa. Mtengo wa ma bolts ndi zomangira za guardrail mumzinda wa Meizhou, Chigawo cha Guangdong nthawi zambiri ulibe mapindikidwe ambiri, kotero kuchuluka kwa m'malo kumakhala kochepa; Kukonzekera kwa mbale ya guardrail ndikokwera kwambiri. Galimotoyo ikagunda, mbale ya guardrail imayenera kusinthidwa, chifukwa mbale ya guardrail mu mzinda wa Baotou mumzinda wa Inner Mongolia ikufunika kupotozedwa kuti ichedwetse mphamvu.
Chifukwa chake, kukonza mbale ya guardrail bolt ndikokwera kwambiri kuposa bawuti ya chingwe guardrail. Mzinda wa Yancheng m'chigawo cha Jiangsu Highway Crash Barrier Bolt Kukhazikitsa Mtengo: Kukhazikitsa mfundo pamwamba pa zonse sikovuta kupeza ubwino wa chingwe guardrail bawuti ndi zoonekeratu, koma chingwe mpanda bawuti ndi apamwamba kuposa mtengo wa gulu mpanda, chifukwa alonda. mbale ya njanji yotsika mtengo, kotero mbale ya highway guardrail bawuti imayikidwa pazambiri. Komabe, ndikofunikira kwambiri kukhazikitsa ma bolts a cable guardrail m'malo ena oopsa, monga misewu ya m'mphepete mwa nyanja, misewu yam'mphepete mwa mapiri, misewu yamapiri ndi zina zotero.
