Mutauro weChinese unonakidza chaizvo. Izwi rimwechete rinogona kuita zvakasiyana kana richishandiswa mumamiriro akasiyana. Somuenzaniso, shoko rokuti "shui bao" rinoreva kusatarisira uye kusiya vamwe. Zvinogonawo kuwedzerwa kureva kuti vaviri vanopopotedzana vorambana nekuda kwekusawirirana. Iri izwi rinonyanya kushandiswa mumamota.
Kuraswa kwebhegi irondedzero yekukanganisa kwemaronda rotor motors, izvo zvinoreva mhedzisiro yeradial yekunze deformation ye rotor inotenderera inopera nekuda kwekumhanyisa. Kana tichiziva chimwe chinhu pamusoro pemaronda rotor motors, tinogona kuona kuti kune zvimwe zvirambidzo pakumhanya kwerudzi urwu rwemotokari. Kubva pahuwandu hwemapango, kune mamwe mamotor ane 6 mapango kana kupfuura, izvo zvinoreva kuti iyo yakatemerwa kumhanya kwayo idiki; vamwe vagadziri vemota vanogadzira 4-pole ronda rotor motors, asi maitiro ekugadzira akaomesesa, uye mhepo yerotor inofanirwa kuongororwa kuvimbika kwepamusoro.
Kugadzirwa chaiko uye kuoneswa kunoratidza kuti iyo yakaoma mhepo inotenderedza rotor ine simba rakasimba rekudzivirira iyo pasuru kubva kukandwa kure kupfuura iyo yakapfava inomonereka rotor; uyezve, iyo inodiwa kugadzirisa, kusunga, varnishing uye kurapa matanho ekupedzisira emhepo zvinhu zvakanyanya kukosha. Ehe, kana yakawedzera kukurumidza kumisa mudziyo ichiwedzerwa panguva yekushanda kwemota, dambudziko iri rinogadziriswa.

Chikonzero chakakosha chekukanda kwepakeji ndeye centrifugal maitiro
Chinhu chinoita circular motion, nekuda kwe inertia yacho pachayo, chinogara chiine katsika kekubhururuka tichitevedza mativi edenderedzwa. Kana simba rekunze rakasanganiswa rinobva ranyangarika kana kuti risakwana kupa simba repakati rinodiwa pakufamba kwedenderedzwa, rinofamba zvishoma nezvishoma kubva pakati pedenderedzwa. Chiitiko ichi chinonzi centrifugal phenomenon.
Munguva yekushanda kwemotokari, chikamu chimwe nechimwe chechikamu che rotor chinofamba mumhepo inotenderera yakakomberedza pakati pemotokari shaft. Zvinoenderana nehukama pakati pekukurumidza uye simba recentrifugal mukutenderera kwedenderedzwa, iyo yakakura kumhanya, inowedzera simba recentrifugal.
Inowanzoonekwa muhupenyu ndeyekuwachisa madhiramu ekubvisa mvura, donje kugadzira zvihwitsi, etc. Centrifugal speed regulators, centrifugal testers, centrifugal dryers, centrifugal precipitators, washing machine dehydration barrels, cotton candy kugadzira, otomatiki mari yekuronga michina, discus uye sando kukanda makwikwi mumakwikwi emitambo yemakwikwi, etc.
Zvose zvine zvazvakanakira nezvazvakaipira. Nekuda kweiyo centrifugal simba, dzimwe tsaona dzinogona kuitika, zvichikonzera kukuvadza kuhupenyu hwevanhu. Kune mota dzinotyaira mumigwagwa yakachinjika, simba repakati rinodiwa pakutendeuka rinopihwa nekukwenya kwakamira pakati pemavhiri nepamusoro pemugwagwa. Kana sipidhi yakanyanyisa pakutendeuka, simba repakati rinodiwa F rakakura kudarika rinonyanya kumira, uye motokari ichaita centrifugal motion uye kukonzera tsaona dzemotokari. Naizvozvo, mota hadzitenderwe kudarika kumhanya kwakatarwa pamakona emugwagwa. High-speed inotenderera inokuya mavhiri, flywheels, etc. kazhinji inoputika uye inopfura kunze kwekumhanya kwepamusoro nekuda kwesimba rezvinhu uye kuputika kwemukati.

Chii chinonzi centrifugal force?
Centrifugal force is a virtual force, kuratidzwa kweinertia, iyo inofambisa chinhu chinotenderera kubva panzvimbo yayo yekutenderera. MuNewtonian mechanics, centrifugal force yakashandiswa kuratidza pfungwa mbiri dzakasiyana: inertial force inoonekwa mu non-inertial reference frame frame, uye balance yecentripetal force. MuLagrangian mechanics, simba recentrifugal dzimwe nguva rinoshandiswa kutsanangura masimba akajairwa pasi peiyo generalized coordination system.
Muchirevo chenguva dzose, centrifugal force haisi simba chairo. Basa rayo ndere kuona chete kuti mitemo yaNewton yekufamba ichikwanisa kushandiswa mukutenderera kwereferensi. Iko hakuna centrifugal simba muinertial referensi furemu, uye inertial simba rinongodiwa mune isiri-inertial referensi furemu.
Fungidzira dhisiki rinotenderera rakatenderedza pakati paro rine angular velocity ye ω. Pamusoro pe diski ivhavha yehuni yehuwandu m, yakabatanidzwa netambo, imwe mugumo wayo inogadziriswa pakati pe diski (uyewo pakati pekutenderera). Kureba kwetambo ndi r. Chivharo chehuni chinotenderera ne diski. Tichifunga kuti hapana kukakavara, chivharo chehuni chinotenderera nekuda kwekukakavadzana kwetambo. Kune mucherechedzi anotenderera nedhisiki, danda remuti rakamira. Maererano nemutemo waNewton, simba remambure padanda rehuni rinofanira kuva zero. Zvisinei, chivharo chehuni chinongozviisa pasi pesimba rimwe chete, kushushikana kwetambo, saka simba remambure harisi zero. Izvi zvinotyora mutemo waNewton here? Mutemo waNewton unoshanda chete muinertial system, asi iyo referensi system yeanocherekedza inotenderera ne diski isiri-inertial system, saka mutemo waNewton haubati pano. Kuti mutemo waNewton urambe wakabatirira mune isiri-inertial system, inertial force, inova centrifugal force, inoda kutaurwa.
Ukuru hwesimba re centrifugal hwakaenzana nekukakavadzana kunopiwa netambo, asi kutungamira kunopesana. Mushure mokunge simba re centrifugal rinotangwa, kubva pakuona kwemucherechedzi ari kutenderera ne diski, chivharo chehuni panguva imwe chete chinoiswa pasi pekumanikidzwa kwetambo uye simba re centrifugal, iro rakaenzana muhukuru uye rakapesana munzira, uye simba remambure ndiro zero. Panguva ino, danda remapuranga rakamira, uye mutemo waNewton unobata chokwadi.
