Kuongorora uye Kuvandudzwa kweKudonha Kwemvura Kukanganisa kweGround Radar Mvura Hinge_Hinge Knowledge

Abstract: Ichi chinyorwa chinopa ongororo yakadzama yenyaya yekuvuza mune yepasi radar mvura hinge. Inozivisa nzvimbo yekukanganisa, inosarudza chikonzero chikuru chekukanganisa, uye inokurudzira matanho ekuvandudza. Kushanda kwematanho aya kunozosimbiswa kuburikidza ne mechanical simulation analysis uye kuyedzwa.

Sezvo radar tekinoroji masisitimu ari kuramba achishanduka, kudiwa kwesimba rekufambisa radar kuri kuwedzera, kunyanya nekufamba kuenda kune akakura arrays uye data hombe. Nzira dzechinyakare dzekutonhodza mhepo hadzichakwani kuzadzisa zvinodiwa zvekutonhodza zveaya maradha makuru. Kutonhodza radar kumberi kwakakosha, kunyangwe maradhi epasi emazuva ano ari kushandura kubva ku mechanika scanning kuenda kuchikamu chekuongorora. Nekudaro, mechanical azimuth kutenderera ichiri kudikanwa. Uku kutenderera uye kutapurirana kweinotonhodza pakati pemidziyo yepamusoro inowanikwa kuburikidza nemvura inotenderera majoini, anozivikanwawo semahinji emvura. Kuita kwehinji yemvura kunokanganisa zvakananga kuita kwese kweiyo radar yekutonhodza system, zvichiita kuti ive yakakosha kuve nechokwadi chekuvimbika uye hupenyu hurefu hwehinge yemvura.

Tsanangudzo Yekukanganisa: Iko kukanganisa kwekuvuza mune radar yemvura hinge inoratidzwa nekuwedzera kwehuwandu hwekudonha nekurebesa kuenderera kutenderera nguva yeantenna. Iyo yakanyanya kudonha chiyero inosvika 150mL / h. Pamusoro pezvo, chiyero chekuvuza chinosiyana zvakanyanya kana antenna yakamira panzvimbo dzakasiyana dzeazimuth, ine yakanyanya kudonha chiyero ichionekwa munzira inofananidzwa nemuviri wemotokari (inoda kusvika 150mL / h) uye yakaderera munzira yakatarisana nemuviri wemotokari (inotenderedza 10mL. /h).

Mhosva Nzvimbo uye Chikonzero Ongororo: Kuti uone nzvimbo yekukanganisa kwekudonha, kuongororwa kwemuti wemhosva kunoitwa, uchifunga nezvemukati weiyo hinge yemvura. Ongororo iyi inodzinga zvimwe zvingave zvichibva pa pre-installation pressure tests. Zvinotemerwa kuti chikanganiso chiri muchisimbiso chine simba 1, icho chinokonzereswa nenyaya yekubatanidza pakati pehinji yemvura uye mhete yekuunganidzira panguva yegungano. Kupfekedzwa kweinoteed slip ring inodarika kugona kwemuripo weO-ring, zvichitungamira mukukundikana kwechisimbiso uye kubuda kwemvura.

Mechanism Analysis: Kuyera chaiko kunoratidza kuti torque yekutanga yeringi inotsvedza i100N·m. A finite element modhi inogadzirwa kutevedzera maitiro ehinge yemvura pasi pemamiriro ezvinhu akanaka uye mitoro isina kuenzana inokonzerwa neinotsvedza ring's torque uye yaw angle. Ongororo iyi inoratidza kuti kutsauka kwemukati shaft, kunyanya kumusoro, kunotungamira mukutsikirira mwero kusiyana pakati pezvisimbiso zvine simba. Dynamic chisimbiso 1 inosangana nekupfeka kwakanyanya uye kudonha nekuda kweiyo eccentric mutoro wakakonzerwa nekubatana pakati pehinge yemvura uye mhete yekutsauka.

Matanho ekuvandudza: Zvichienderana nezvikonzero zvekutadza zvakaonekwa, kuvandudzwa kunotevera kunorongwa. Chekutanga, chimiro cheiyo hinge yemvura inoshandurwa kubva pakurongeka kweradial kuenda kuaxial kurongeka, ichidzikisa hukuru hwayo hweaxial uku ichichengeta chimiro chepakutanga uye machinjiro asina kuchinjika. Chechipiri, nzira yekutsigira yezvindori zvemukati nekunze zvehinge yemvura inovandudzwa nekushandisa angular contact bearings nekugovera kwepairi kumativi ose maviri. Izvi zvinovandudza hinge yemvura inopesana nekufamba.

Mechanical Simulation Analysis: Iyo nyowani inopera element modhi inogadzirwa kuti iongorore maitiro eiyo yakagadziridzwa hinge yemvura, kusanganisira ichangobva kuwedzerwa eccentricity yekubvisa mudziyo. Ongororo iyi inosimbisa kuti kuwedzera kweiyo eccentricity yekubvisa mudziyo zvinobudirira kubvisa kutsauka kunokonzerwa nekubatana pakati pemhete yekutsauka uye hinge yemvura. Izvi zvinovimbisa kuti shaft yemukati yehinge yemvura haichagadziriswi nemitoro eccentric, nokudaro inovandudza hupenyu uye kuvimbika kwehinge yemvura.

Verification Mhedzisiro: Iyo hinge yemvura yakagadziridzwa inoedzwa yakamira-yekuita, bvunzo dzekumanikidza mushure mekubatanidza kutenderera kusanganiswa nemhete yekutsauka, bvunzo dzekuisa muchina, uye bvunzo dzakakura dzemunda. Mushure memaawa makumi mapfumbamwe nematanhatu ekukopa bvunzo uye 1 gore remumunda debugging bvunzo, yakagadziridzwa hinge yemvura inoratidza kuita kwakanakisa pasina kukundikana.

Nekuita kuvandudzwa kwezvimiro uye nekuwedzera eccentricity yekubvisa mudziyo, iyo deflection nyaya pakati pehinge yemvura neinounganidzira mhete inodzorwa zvinobudirira. Izvi zvinovimbisa hupenyu hurefu uye kuvimbika kwehinge yemvura, kuderedza njodzi yekudonha. Iyo mechanical simulation ongororo uye test verification inosimbisa kushanda kweizvi kuvandudzwa.
