AAR M-112 nezvimwe zvitubu zvakajairika
Basic information
Railway wagon simbi chitubu chinhu chakakosha ngoro chikamu, icho chinoshandiswa zvakanyanya mumotokari dzenjanji sezvitima, subways uye trams.Inonyanya kushandiswa kutsigira uye kuvharidzira kuzunguzika uye kukanganisa kwengoro kuti ive nechokwadi chekuchengetedza uye kunyaradza kwengoro panguva yekutyaira.
Chekutanga, njanji ngoro dzesimbi zvitubu zvine elasticity uye simba rakanaka.Yakagadzirwa nesimbi yakasimba-yakasimba, yakagadzirwa nehunyanzvi uye yakagadziridzwa, ine yakakwirira-yekutakura mitoro uye elastic deformation kugona.Izvi zvinogonesa chitubu chesimbi kuti chikwanise kumira kuzunguzika kukuru uye kuvhunduka kunoitwa nengoro paunenge uchityaira, uye panguva imwe cheteyo nekukasira kudzoka kuchimiro chayo chepakutanga kuti ive nechokwadi chekugadzikana uye kutasva nyaradzo.
Chechipiri, zvitubu zvesimbi zvine zvakanakisa corrosion resistance uye kuneta kuramba.Nekuti mota dzinowanzo kuoneswa nharaunda dzakakasharara, senge hunyoro, huruva, tembiricha yakakwira, nezvimwe, zvitubu zvesimbi zvinoda kuve nekudzivirira kwakanakisa kwecorrosion kuti vave nechokwadi chehupenyu hwavo hurefu.Panguva imwecheteyo, panguva yekumhanya kwemotokari, chitubu chesimbi chinowanzo kukanganiswa nekuzunguza uye mutoro, saka inoda kuve neakanaka kuneta kuramba kuti ive nechokwadi chekushanda kwakavimbika kwenguva yakareba.Mukuwedzera, zvitubu zvesimbi zvakare zvine tembiricha yepamusoro yekushanda uye kuchinjika kwezvakatipoteredza.Tembiricha munzvimbo dzakasiyana uye mwaka inosiyana zvakanyanya, saka zvitubu zvesimbi zvinoda kukwanisa kuchinjika kune dzakasiyana tembiricha nharaunda uye kuchengetedza kushanda kwakagadzikana.Panguva imwecheteyo, zvitubu zvesimbi zvinodawo kukwanisa kuenderana nemamiriro akasiyana-siyana emigwagwa uye mamiriro ekushanda, akadai sekutyaira-mutsetse, kutyaira, kukwira nekudzika, nezvimwewo, kuve nechokwadi chekuchengetedzwa uye kugadzikana kwekushanda kwemotokari.
Kupfupisa, zvitubu zvesimbi zvemotokari dzenjanji zvinhu zvakakosha kuti ive nechokwadi chekuchengetedzwa kwengoro uye kutasva nyaradzo.Iyo ine yakanaka elasticity uye simba, corrosion kuramba uye kuneta kuramba, pamwe nepamusoro tembiricha yekushanda uye kuchinjika kwezvakatipoteredza.Aya maitiro anoita kuti zvitubu zvesimbi zvitore basa rakakosha rekutsigira uye kubhafa mumotokari dzechitima, kuve nechokwadi chekushanda kwakachengeteka kwenjanji.
