Isitho (ingxenye 3): izinhlobo zama-tracture

Izinhlobo ezahlukahlukene zama-tracture adlala isitho:

Imishini

• Lolu hlobo lwe-tracture luvame kakhulu namuhla futhi luyinkomba.
• Ngenxa yokuguquguquka kwayo, kungenzeka ukwenza cishe noma yimuphi umsebenzi ensimbini ene-tracture yomshini, kungakhathaliseki ukuthi inkathi yokwakhiwa kwayo. Ngaphezu kwalokho, kuphela ensimbini ene-tracture yomshini lapho umculi angafinyelela khona ikhono eliphezulu lokudlala.
• Umsindo wesitho nawo ulawulwa ngokunembe kakhulu. Kodwa ngenxa yokuthi yonke imizamo idluliselwa kumapayipi kuphela ngosizo lwamandla emisipha yomculi, imingcele eqinile iphakama ebeka umkhawulo ubukhulu namandla ensimbi.
• Ezithweni ezinkulu kunazo zonke (lezi ezinamarejista angaphezu kwekhulu), ukudonsa ngomshini akusebenzi nhlobo, noma kusetshenziswe kanye ne-Barker pneumatic amplifier ekhethekile.

I-pneumatic

• Ngokuvamile, i-tractura enjalo ingatholakala kumathuluzi adalwe esikhathini kusukela ekupheleni kweshumi nesishiyagalolunye kuya ekuqaleni kwekhulu lamashumi amabili.
• Epheshaneni elinjalo, lapho umculi ecindezela ukhiye, i-valve ye-pneumatic ye-control air duct iyavuleka. Naye, uvula ukunikezwa komoya kwelinye noma eziningana zamapayipi ethoni efanayo.
• Ngakolunye uhlangothi, leli thuluzi lihle, njengoba i-pneumatic tracture isusa yonke imingcele ngobukhulu besitho kanye nenani lamarejista ayo, futhi ngakolunye uhlangothi, inokubambezeleka kokuzwakala.
• Abanikazi bamakhompyutha angakhiqizi kakhulu bajwayelene nalesi simo lapho bedlala ngaso kukhibhodi ye-midi. Isenzo esinjalo ekuqaleni singaphazamisa kakhulu emdlalweni.

Ugandaganda oxubile

• Ngokuvamile, ama-tractures wemishini kanye ne-pneumatic ahlangene. Lolu hlobo lukagandaganda lunayo yonke imibimbi yawo womabili ogandaganda, ngakho lwalusetshenziswa kuphela kwaze kwaba yilapho sekwakhiwa ogandaganda abathembekile ngokwanele kagesi.

Ugandaganda we-Electropneumatic

• Manje sekuyivelakancane kakhulu ukukhiqiza izitho ezinomshini onjalo wokulawula.
• Eqinisweni, lokhu kuhlukile kwe-pneumatic tracture, kodwa ngokudluliswa kwesignali kagesi esikhundleni semigudu yomoya.

ugandaganda kagesi

• Amapayipi amapayipi ayavulwa futhi avalwe ngokusebenzisa ama-relay okulawula.
• Izitho ezinjalo zazisakazeke kakhulu ekhulwini lamashumi amabili, kodwa manje ziya ngokuya zithathelwa indawo yi-tracture eyenziwa ngomshini.
• Ipheshana likagesi yilona kuphela elingenayo imingcele noma ngenani lamarejista noma ngendawo akuyo ehholo. Ngenxa yalokho, kwaze kwavela ukuthi amarejista angatholakala emaphethelweni ahlukene ehholo, izincwadi ezengeziwe zingafakwa futhi i-duet ingadlalwa, noma ngisho nemisebenzi ye-orchestra.
• Ize yahamba yaze yakwazi ukuqopha ingxenye ethile bese idlala emuva ngaphandle kokuhlanganyela komculi. Uhlobo lwe-multi-ton hurdy-gurdy.
• Kodwa i-tracture enjalo yayine-drawback ephawulekayo: ukungabi khona kwempendulo phakathi kwamapayipi amapayipi neminwe yomculi. Yebo, futhi ukudluliselwa kungasebenza ngokubambezeleka, futhi lokhu kuyisici esibi kakhulu.
• Ukuyiqeda, engxenyeni yokuqala yekhulu lamashumi amabili, ukushintshashintsha kwe-electromechanical ngezinye izikhathi kwakusetshenziswa, futhi lapho kubangelwa, banikeza ukuchofoza kwensimbi. Kodwa uma i-overtones ye-tracture yomshini izwakala kamnandi, imisindo engaphezulu yedrayivu ye-electromechanical kunalokho yonakalisa umbono wegeyimu.

Ugandaganda we-electromechanical

• Manje sekuyiyona ndlela ejwayeleke kakhulu yokulingisa izinsimbi ezinkulu.
• Ngakolunye uhlangothi, ukulawula kanye nokuguquguquka okukhona ezithweni ezine-tracture yemishini kuyagcinwa, futhi ngakolunye uhlangothi, ukulawulwa kagesi kwamarejista amapayipi kulula kakhulu.

Manje, njengangaphambili, i-ogani ivame ukusetshenziselwa ukuhambisana nomculo phakathi nokukhulekela, kanye nokuphelezela ikhwaya. Ngaphezu kwalokho, isetshenziselwa ukwenza izingxenye zesitho kanye nokwenza ngcono ngesikhathi samakhonsathi.

Ngokuvamile, i-tractura enjalo ingatholakala kumathuluzi adalwe esikhathini kusukela ekupheleni kweshumi nesishiyagalolunye kuya ekuqaleni kwekhulu lamashumi amabili.
