Kukuya Ibwe Performance Evaluation Method

Kukuya Ibwe Performance Evaluation Method

Chinhu chinonyanya kukosha chekugadzira dombo rekukuya chiri pakuongorora uye kuona mashandiro ayo (kusanganisira ukuru uye kurongeka, dynamic/static balance, simba rekutenderera, kutakura mutoro, kuita kwekugaya, zvichingodaro), zvichitungamira dhizaini yakagadziridzwa yekuumbwa kwayo, maitiro, uye chimiro. Pakati pezvinhu izvi, kukuya kwebwe rekukuya rinoshanda sechiratidziro chinobatika chekushanda kwayo kwekushanda, kuunganidza kutarisisa kukuru kubva kuvatsvakurudzi. Parizvino, kukuya matombo ekugadzirisa midziyo inogona kuiswa mumhando nhanhatu zvichienderana nekusiyana kwemaitiro echiito mafomu pakati pedombo rekukuya uye njanji: 1) yechinyakare yekukuya muchina mhando; 2) stationary block njanji mhando; 3) linear njanji feed mhando; 4) denderedzwa njanji horizontal rotary feed mhando; 5) high-speed njanji grinding stand; uye 6) njanji chaiyo ichikuya bvunzo mutsetse.

(1) Yakajairika Grinder Type. Uhlmann et al. [1] akaongorora kukanganisa kwekukuya parameter pamhando yepamusoro (kuoma, kushata, kuchena kwerairi) yenjanji uchishandisa grinder yepamusoro inoratidzwa muFigure 1. Wu et al. [2] yakaongororwa kuti dombo rekukuya rinowedzera kunaka kwenjanji mushure mekukuya uchishandisa mudziyo wakafanana. Mhando iyi yekukuya tester inoratidzirwa nepamusoro-soro mutsara wematombo (kusvika ku 30-50 m / s) asi kudya kwakaderera (8-16 m / min) [2]; panguva imwe chete, kudzvinyirirwa kwekukuya hakusi kuchinjika. Nekuda kweizvozvo, muedzi uyu haakwanise kutevedzera mashandiro ekukuya njanji uye anogona kungopa chirevo chekudzidza maitiro ekukuya vhiri.

(2) Stationary Block Rail Type. Zvichienderana nemashandiro emumunda ekukuya matombo ekukuya njanji, nyanzvi dzakawanda dzakabatanidza mota padombo rekukuya uye dzakashandisa panoperera dombo rekukuya njanji. Kanematsu et al. [3] akasimbisa kushanda kwekukuya kwematombo akasiyana-siyana ekukuya achishandisa njanji yekukuya tester inoratidzwa mumufananidzo 2. Gu et al. [4] yakagadzirisa muongorori wekukuya ane chimiro chakafanana achishandisa friction experimental tester kuti aongorore kushanda kwekukuya kwematombo ane hukuru hwakasiyana hwezviyo. Rudzi urwu rwemuchina wekuyedza unogona kutevedzera zvirinani kumhanya kwedombo rekukuya, kudzvinyirirwa, uye mamwe ma paramita asi haugone kuwana kufambisa kwekudya. Kugaya kwenguva refu kwenzvimbo yenjanji kunosimudza tembiricha nekuda kwekudziya kwekukuya, zvichizotungamira mukushatiswa kwematombo ekukuya-resin-bonded patembiricha yakakwira uye kuderera kwesimba rekubata. Uyezve, pasi pesimba rekukuya kupisa, njanji inowanzopisa. Naizvozvo, maitiro ekuyedza emhando iyi yemuchina wekuyedza anofanirwa kufunga zvizere kupindira kwekukuya tembiricha pamhedzisiro yekuyedza.

(3) Linear Rail Feed Type. Kugadzirisa nyaya yekudyisa njanji mumuchina wekuyedza njanji weGu et al. [4], Zhou Kun [80] akashandisa rack uye pinion kutyaira njanji dzebhari, zvichiita kuti unidirectional, linear rail feeding kubva ku1.6 kusvika ku4.0 km / h, sezvinoratidzwa mumufananidzo 3. Muchina wekuedza wakashandiswawo kudzidza maitiro akasiyana-siyana ekukuya (kukuya kudzvinyirirwa [5], kuomeswa kwekudya [76]. Huang Guigang [8] yakagadzirisa chimiro chikuru cheBM2015 gantry planer kuti igadzire njanji yakatwasuka inoshanda ichikuya tester, inoratidzwa muMufananidzo 4. Midziyo yakashandiswa 60 kg/m gauge rail pa-site, ine kufananidzwa kwekudya kwekumhanya kwe0.3 ~ 4.5 km / h, uye inogona kuwana kugaya kwe ± 50 angle. Midziyo yacho yakanyatso simbisa kuita kwekukuya kweiyo yakagadziridzwa CBN yekukuya vhiri. Iyo njanji inoshanda yekukuya kukurumidza kumhanya inotangira pa3 ~ 24 km/h, ukuwo kumhanya kunoedzerwa nerudzi urwu rwezviyo zvekukuya njanji kwakadzikira, zvichidzikamisa kugona kwayo.

(4) Circular Rail Horizontal Rotary Feed Type. The Chinese Academy of Railway Sciences [9], Nanjing University of Aeronautics uye Astronautics [10,11], uye Kuffa et al. yeSwitzerland [12] yakashuma denderedzwa njanji horizontal rotary feed tester, inoratidzwa muMufananidzo 5. Muchiidzi ichi, njanji inogadzirwa mu diski uye yakarongeka yakatwasuka; iyo njanji disc inogona kutenderera yakatwasuka pasi pechiito chedhiraivha dhiraivha kutevedzera kumhanya kwekudya kwemota yekukuya. Midziyo yakagadzirwa neChinese Academy yeRailway Sayenzi inoratidzira dhayamita renjanji ringangoita 1.6 m, bhandi rekukuya rakafara mamirimita gumi, uye kumhanya kukuru kwe10.8 km/h [9]. Zvichienderana nekukuya kwechigadzirwa ichi chekuedza, chinopa tsigiro yedata yekuvandudzwa kwemamiriro ekuraira kweanoshingaira kugaya mavhiri [9,13,14]. Rudzi urwu rwemichina runonyanyozivikanwa mumunda wekushanda njanji kukuya.

(5) High-Speed ​​Rail Kukuya Tester. Chikwata chaWang Hengyu kuSouthwest Jiaotong University [15,16] vakagadzira passive high-speed njanji yekukuya tester inokwanisa kutevedzera yakanyanya kukuya kumhanya inosvika 60~80 km/h, sezvaratidzwa muFigure 6. Uyezve, timu yaProfessor Zou Wenjun paHenan University of Technology [17 grinding a small gri-8] (Mufananidzo 7), uko dhisiki rejanji rakarongedzerwa vertically, uye midziyo inogona kugadzirisa dombo rekukuya nekumanikidza. Iyo dhayamita yekunze yenjanji ndeye 150 mm, uye kutsanangurwa kwedombo rekukuya ndeye Φ80 × 10 × 10 mm, inokwanisa kuenzanisa pa-saiti kugaya kumhanya kwe60 ~ 80 km / h uye kugaya kudzvinyirira kwe 1200 ~ 3200 N. Iyo yekukuya kudzvinyirirwa kwedombo rekukuya kunosvika 6 ~ 8 kukurumidza kukwirisa km 0, kukurumidza kukwirisa 6 ~ 80h. hukuru hwekukuya kudzvinyirirwa kwe3200 N. Mhando iyi yemuchina wekuedza inoita basa rinokosha rinotungamirira mukugadzirwa kwematombo ekukuya anomhanya.

(6) Real Rail Kukuya Test Line. Mumakore gumi adarika, Golden Eagle Heavy Indasitiri yakatanga kuvandudza uye dhizaini yemhando yepamusoro-soro yekukuya njanji uye yakamisa njanji yekukuya bvunzo muYujiahu, Xiangyang Guta, Hubei Province. Mufananidzo wechisere unoratidza motokari inokuya njanji inomhanya zvikuru, iyo inogona kuva nemavhiri 24 ekukuya (12 kurutivi rumwe norumwe), ichishanda nesimba rokukuya rinopfuura 60 km/h [15]. Mamiriro ekushanda kwemotokari uye modhi zvinogona kunyatsoenderana neaya ekuru-kumhanya njanji, zvichigonesa kuongororwa kwekucheka kwedombo rekukuya. Panguva imwe chete, motokari inogadzirwa nematombo akawanda ekukuya, achibvumira kuongororwa kwekugadzikana kwekugadzirwa kwematombo ekukuya. Naizvozvo, pasi pemamiriro ekumisikidza yakazara yekuongorora sisitimu, iyo yeramangwana ongororo uye kuoneswa kwekuita vhiri rekukuya neiyi mota inogaya inobata kukosha kwekutungamira.
