Ubhampa wemoto ungenye yezinsiza ezinkulu emotweni.Inemisebenzi emithathu eyinhloko: ukuphepha, ukusebenza kanye nokuhlobisa.
Kunezindlela ezintathu eziyinhloko zokunciphisa isisindo sobhampa bezimoto: izinto ezingasindi, ukwenziwa ngcono kwesakhiwo, kanye nokusungulwa kwenqubo yokukhiqiza.Isisindo esilula sezinto ezisetshenziswayo ngokuvamile sibhekisela ekushintsheni izinto zangempela ngezinto ezinomthamo ophansi ngaphansi kwezimo ezithile, njengensimbi eyenziwe ngepulasitiki;idizayini yokwenza ngcono ye-bumper engasindi ikakhulukazi inezindonga ezincane;inqubo entsha yokukhiqiza ine-micro-foaming.Ubuchwepheshe obusha njengezinto zokwakha kanye nokubumba okusizwa ngegesi.
Amapulasitiki asetshenziswa kakhulu embonini yezimoto ngenxa yesisindo sawo esilula, ukusebenza kahle, ukukhiqiza okulula, ukumelana nokugqwala, ukumelana nomthelela, kanye nezinga elikhulu lenkululeko ekwakhiweni, futhi asetshenziswa kakhulu ezintweni zezimoto.Inani lepulasitiki elisetshenziswa emotweni seliphenduke enye yezindlela zokukala izinga lokuthuthuka kwemboni yezimoto yezwe.Njengamanje, ipulasitiki esetshenziswa ekukhiqizeni imoto emazweni athuthukile isifinyelele ku-200kg, okuhlanganisa cishe u-20% wekhwalithi yemoto ephelele.
Ipulasitiki isetshenziswa embonini yezimoto yaseChina sekudlule isikhathi uma kuqhathaniswa.Ezimotweni ezongayo, inani lamapulasitiki lingama-50 ~ 60kg kuphela, ezimotweni ezisezingeni eliphakathi nezisezingeni eliphezulu, 60~80kg, kanti ezinye izimoto zingafinyelela ku-100kg.Lapho kukhiqizwa amaloli aphakathi nendawo eShayina, yonke imoto Isebenzisa cishe u-50kg wepulasitiki.Ukusetshenziswa kwepulasitiki kwemoto ngayinye kungu-5% kuya ku-10% kuphela wesisindo semoto.
Izinto ze-bumper ngokuvamile zinezidingo ezilandelayo: ukumelana nomthelela omuhle kanye nokumelana nesimo sezulu esihle.Ukunamathela kahle kopende, uketshezi oluhle, ukusebenza kahle kokucubungula kanye nenani eliphansi.
Ngakho-ke, izinto ze-PP ngokungangabazeki ziyisinqumo esingabizi kakhulu.Impahla ye-PP iyipulasitiki yenjongo evamile esebenza kahle kakhulu, kodwa i-PP ngokwayo inokusebenza okungekuhle okunezinga lokushisa eliphansi nomthelela wokumelana nomthelela, ayikwazi ukumelana nokugqokwa, ukuguga kulula futhi inozinzo oluphansi lobukhulu.Ngakho-ke, i-PP eguquliwe ijwayele ukusetshenziselwa ukukhiqizwa kwebhampa yemoto.impahla.Njengamanje, izinto ezikhethekile zamabhampa ezimoto e-polypropylene zivame ukwenziwa nge-PP, futhi ingxenye ethile yerabha noma i-elastomer, i-inorganic filler, i-masterbatch, izinto ezisizayo nezinye izinto ziyaxutshwa futhi zicutshungulwe.
Izinkinga ezibangelwa udonga oluncane lwebhampa nezisombululo
Ukuncipha kwe-bumper kulula ukubangela i-warping deformation, futhi i-warping deformation ingumphumela wokukhululwa kokucindezeleka kwangaphakathi.Obhampa abanezindonga ezincane bakha ukucindezelwa kwangaphakathi ngezizathu ezahlukahlukene phakathi nezigaba ezahlukahlukene zokubumba umjovo.
Ngokuvamile, kuhlanganisa ikakhulukazi ingcindezi yokuma, ingcindezi yokushisa, kanye nengcindezi yokukhululwa kwesikhunta.Ukucindezeleka kokuma kuwukukhanga kwangaphakathi okubangelwa imicu, amaketanga e-macromolecular noma amasegimenti ekuncibilikeni okuqondiswe endaweni ethile kanye nokuphumula okunganele.Izinga lokuma lihlobene nobukhulu bomkhiqizo, izinga lokushisa lokuncibilika, izinga lokushisa lesikhunta, ingcindezi yomjovo, nesikhathi sokuhlala.Ubukhulu obukhulu, i-degree of orientation iyancipha;izinga lokushisa elincibilikayo liphakeme, i-degree of orientation iyancipha;izinga lokushisa eliphakeme lesikhunta, i-degree of orientation iyancipha;ingcindezi yomjovo iphezulu, izinga lokuma liphezulu;uma isikhathi sokuhlala sisinde, izinga lokuma liba likhulu .
Ukucindezeleka okushisayo kungenxa yokushisa okuphezulu kokuncibilika kanye nezinga lokushisa eliphansi lesikhunta ukwenza umehluko omkhulu wokushisa.Ukupholisa kokuncibilika eduze komgodi wesikhunta kuyashesha futhi ukucindezeleka kwangaphakathi komshini kusatshalaliswa ngokungalingani.
Ingcindezi yokudiliza ibangelwa ikakhulukazi ukungabi namandla kanye nokuqina kwesikhunta, ukuguqulwa kwe-elastic ngaphansi kwesenzo sokucindezela komjovo namandla okukhipha, kanye nokusatshalaliswa okungalingani kwamandla lapho umkhiqizo ukhishwa.
Ukucwiliswa kukabhampa kubuye kube nenkinga yokuwudiliza.Ngenxa yokuthi i-gauge yokuqina kodonga incane futhi inenani elincane lokunciphisa, umkhiqizo unamathela ngokuqinile ekubunjeni;ngoba ijubane lomjovo liphakeme kakhulu, isikhathi sokuhlala siyagcinwa.Ukulawula kunzima;ukuqina kodonga oluncane kanye nezimbambo nakho kusengozini yokulimala ngesikhathi sokudilizwa.Ukuvulwa okuvamile kwesikhunta kudinga umshini wokujova ukuze unikeze amandla okwanele okuvula isikhunta, futhi amandla okuvula isikhunta kufanele akwazi ukunqoba ukumelana lapho uvula isikhunta.
