I roto i te ao nui o te hanga waka rererangi, he mea nui ia karamu. I te piki haere o te rere ā-wāhi arumoni me te horapa haere o ngā tono waka rererangi kore, ka tūtaki te umanga ki tētahi wero rua kāore i kitea i mua: te whakatutuki i te whakaiti taumaha mōrahi me te pupuri tonu i te pumau o te hanganga. Kua puta ake ngā wāhanga hanganga tika o te muka waro hei otinga tuturu, me te tautokona e ngā taunakitanga whaimana.
E whakaatu ana tēnei pūrongo i ngā inenga mahi matua e whā mai i ngā whakamātautau pakari e whakaatu ana he aha ngā rauemi muka waro e noho nei hei rauemi whiriwhiri mō ngā wāhanga hanganga rererangi.
Ine 1: Kaha Motuhake – Te Tauwehenga Taumaha-ki-Kaha e Whakamārama Anō ana i te Whai Huatanga
Whakataurite Raraunga Whakamātautau:
| Rauemi | Kaha Kume (MPa) | Kiato (g/cm³) | Kaha Motuhake (MPa·cm³/g) |
|---|---|---|---|
| Hanganga muka waro (tohu T800) | 5,690 | 1.76 | 3,233 |
| Konumohe Koranu 7075-T6 | 572 | 2.70 | 212 |
| Rino Kaha-Teitei | 1,500 | 7.85 | 191 |
Kitenga Matua: Ko te kaha motuhake o ngā rauemi muka waro he 15 ngā wā teitei ake i ngā koranu konumohe, ā, 17 ngā wā teitei ake i te maitai kaha-teitei.
Pānga o te Ao Tūturu:
Mō ngā kaihanga rererangi, ka puta he painga whakahaere mō tēnei:
- Ngā Whakamahinga Amiorangi: Ia whakaitinga 1 kg o te taumaha amiorangi ka penapenahia te 500 kg o te wahie rōkete, ā, ka whakaitihia ngā utu whakarewatanga mā te $20,000.
- Utaina o te Taraneti: Ka taea e ngā wāhanga hanganga muka waro te whakanui ake i te kaha utaina mā te 30-40% ki te whakaritea ki ngā mea rite ki te konumohe.
- Te Whai Hua o te Wahie: Ka whakaitihia te taumaha o ngā waka rererangi arumoni e whakamahi ana i ngā hiato muka waro ki te 20-25%, ā, ka nui ake te penapena wahie i te roanga o te wā mahi.
Ine 2: Tauwehenga Whānui Wera – Te Pūmautanga Ahu puta noa i ngā Pāmahana Tino Nui
Whakataurite Raraunga Whakamātautau:
| Rauemi | Tauwehenga o te Whakawhanuitanga Wera (CTE) (10⁻⁶/K) |
|---|---|
| Whakakotahi muka waro (whakaroa) | -0.5 ki te 0.5 |
| Konumohe Koranu 6061 | 23.6 |
| Titanium Alloy Ti-6Al-4V | 9.0 |
| Kowiri tira 304 | 17.3 |
