Hei tikanga tuku, he whānuitia te whakamahinga o te taputapu aorangi i roto i ngā mahi hangarau maha, pērā i te whakaiti taputapu, te kerēne, te whakaiti taputapu aorangi, me ētahi atu. Mō te whakaiti taputapu aorangi, ka taea te whakakapi i te tikanga tuku o te tereina taputapu toki pumau i roto i te maha o ngā wā. Nā te mea ko te tukanga tuku taputapu he hononga raina, ka pakaru te taputapu i te hononga roa, nō reira me whakatauira tōna kaha. I whakamahia e Li Hongli me ētahi atu te tikanga hononga aunoa hei hono i te taputapu aorangi, ā, i kitea he rārangi te taipana me te ahotea mōrahi. I honoa anō hoki e Wang Yanjun me ētahi atu te taputapu aorangi mā te tikanga whakaputa aunoa, ā, i whakatauira i te āhua pumau me te whakatauira aratau o te taputapu aorangi. I roto i tēnei pepa, ko ngā huānga tetrahedron me te hexahedron te nuinga e whakamahia ana hei wehewehe i te whatunga, ā, ka tātarihia ngā hua whakamutunga kia kitea ai mēnā kua tutuki ngā tikanga kaha.

1、 Te whakatūnga tauira me te tātari hua

Te whakatauira toru-ahu o ngā taputapu aorangi

Taputapu aorangiKo te nuinga o te mea he taputapu mowhiti, he taputapu rā, he taputapu aorangi. Ko ngā tawhā matua i tīpakohia i roto i tēnei pepa ko: ko te maha o ngā niho o te mowhiti taputapu o roto ko te 66, ko te maha o ngā niho o te taputapu rā ko te 36, ko te maha o ngā niho o te taputapu aorangi ko te 15, ko te diameter o waho o te mowhiti taputapu o roto ko te 150 mm, ko te modulus ko te 2 mm, ko te koki pēhanga ko te 20 °, ko te whānui o te niho ko te 20 mm, ko te tauwehenga teitei tāpiri ko te 1, ko te tauwehenga whakamuri ko te 0.25, ā, e toru ngā taputapu aorangi.

Tātaritanga whakatauira pūmau o ngā taputapu aorangi

Tautuhia ngā āhuatanga rauemi: kawemai i te pūnaha taputapu aorangi toru-ahu i tuhia i roto i te pūmanawa UG ki roto i te ANSYS, ka whakatakoto i ngā tawhā rauemi, e whakaaturia ana i te Ripanga 1 i raro nei:

Te Whakapūtanga: Ka wehea te pūtanga huānga mutunga kore e te tetrahedron me te hexahedron, ā, ko te rahi taketake o te huānga he 5mm. Mai i tetaputapu aorangi, kei roto i te hononga o te taputapu rā me te mowhiti taputapu o roto, ā, kei roto i te mata, ka whakakīkītia te mata o ngā wāhanga hononga me te mata, ā, ko te rahi he 2mm. Tuatahi, ka whakamahia ngā mata toru-toru, e whakaaturia ana i te Pikitia 1. 105906 ngā huānga me 177893 ngā pona ka hangaia katoatia. Kātahi ka whakamahia te mata toru-toru, e whakaaturia ana i te Pikitia 2, ā, ka hangaia katoatia he 26957 ngā pūtau me 140560 ngā pona.

Te tono kawenga me ngā tikanga rohe: e ai ki ngā āhuatanga mahi o te taputapu aorangi i roto i te whakaiti, ko te taputapu rā te taputapu taraiwa, ko te taputapu aorangi te taputapu taraiwa, ā, ko te putanga whakamutunga mā te kawe aorangi. Whakauhia te mowhiti taputapu o roto i roto i te ANSYS, ka whakamahia he taipana o te 500N · m ki te taputapu rā, e whakaaturia ana i te Pikitia 3.

Te tukatuka i muri me te tātari hua: Kei raro nei te kauwhata nekehanga me te kauwhata ahotea ōrite o te tātari pūmau i whiwhi mai i ngā wehenga whatunga e rua, ā, ka whakahaerehia he tātari whakatairite. Mai i te kauwhata nekehanga o ngā momo whatunga e rua, i kitea ko te nekehanga mōrahi ka puta i te tūranga kāore te taputapu rā e hono ki te taputapu aorangi, ā, ko te ahotea mōrahi ka puta i te pūtake o te whatunga taputapu. Ko te ahotea mōrahi o te whatunga tetrahedral he 378MPa, ā, ko te ahotea mōrahi o te whatunga hexahedral he 412MPa. Nā te mea ko te rohe tuku o te rauemi he 785MPa, ā, ko te tauwehenga haumaru he 1.5, ko te ahotea whakaaetia he 523MPa. Ko te ahotea mōrahi o ngā hua e rua he iti iho i te ahotea whakaaetia, ā, e tutuki ana i ngā tikanga kaha e rua.

2. Whakamutunga

Mā te whakatauira huānga mutunga kore o te taputapu aorangi, ka whiwhihia te nephogram whakarerekētanga nekehanga me te nephogram ahotea ōrite o te pūnaha taputapu, mai i reira ka kitea ngā raraunga mōrahi me te iti rawa me tō rātou tohatoha i roto i tetaputapu aorangiKa kitea te tauira. Ko te wāhi o te ahotea ōrite mōrahi ko te wāhi hoki e tino tūpono ai te pakaru o ngā niho taputapu, nō reira me aro nui ki a ia i te wā hoahoa, i te wā hanga rānei. Mā te tātari i te pūnaha katoa o te taputapu aorangi, ka whakakorea te hapa i puta mai i te tātari i te niho taputapu kotahi anake.
