Ko te take i tino rongonui ai ngā rama tiriti pūngao-rā, nā te mea ko te pūngao e whakamahia ana mō te whakamārama i ahu mai i te pūngao-rā, nō reira, kāore he utu hiko o ngā rama pūngao-rā. He aha ngā taipitopito hoahoa ongā rama tiriti pūngaoKoinei te kupu whakataki mō tēnei āhuatanga.
Ngā taipitopito hoahoa o te rama tiriti solar:
1) Hoahoa anga
Kia whiwhi ai ngā waeine pūtau rā i te nui o te hihi o te rā e taea ana i roto i te tau, me whiriwhiri e tātou te koki honga tino pai mō ngā waeine pūtau rā.
Ko te matapakinga mō te piko tino pai o ngā kōwae pūtau pūngao rā e ahu mai ana i ngā rohe rerekē.
2) Hoahoa ātete-hau
I roto i te pūnaha rama tiriti pūngao rā, ko te hoahoa ātete hau tētahi o ngā take tino nui o te hanganga. Ko te hoahoa ātete hau e wehea ana kia rua ngā wāhanga matua, ko tētahi ko te hoahoa ātete hau o te whāriki pākahiko, ko tētahi ko te hoahoa ātete hau o te pou rama.
(1) Te hoahoa ātete hau o te whāriki mōrahi pūtau rā
E ai ki ngā raraunga tawhā hangarau o te waeine pākahikokaihanga, ko te pēhanga hau whakarunga ka taea e te waeine pūtau rā te tu atu ko te 2700Pa. Mena ka tīpakohia te tauwehenga ātete hau ko te 27m/s (he rite ki te awhiowhio he 10 te kaha), e ai ki te wai kore-waikawa, ko te pēhanga hau e mau ana i te waeine pākahiko he 365Pa anake. Nō reira, ka taea e te waeine tonu te tu atu i te tere hau o te 27m/s me te kore e pakaru. Nō reira, ko te mea nui hei whakaaro i roto i te hoahoa ko te hononga i waenga i te whāriki waeine pākahiko me te pou rama.
I roto i te hoahoa o te pūnaha rama tiriti whānui, ko te hononga i waenga i te whāriki pākahiko me te pou rama he mea hanga kia mau, kia honoa hoki e te pou pūtu.
(2) Te hoahoa ātete hau opou rama tiriti
Ko ngā tawhā o ngā rama tiriti e whai ake nei:
Te piko o te panera pākahiko A=15o te teitei o te pou rama=6m
Hoahoahia, ā, tīpakohia te whānui whakarewa i te raro o te pou rama δ = 3.75mm te whānui o waho o te pou rama=132mm
Ko te mata o te whakarewa ko te mata pakaru o te pou rama. Ko te tawhiti mai i te pūwāhi tatau P o te ātete ātete W i runga i te mata rahunga o te pou rama ki te rārangi mahi o te kawenga mahi o te papa pākahiko F i runga i te pou rama ko
PQ = [6000+（150+6）/tan16o] × Sin16o = 1545mm=1.845m。 Nō reira, ko te wā mahi a te kawenga hau i runga i te mata pakaru o te pou rama M=F × 1.845。
E ai ki te hoahoa, ko te tere hau mōrahi e whakaaetia ana he 27m/s, ko te kawenga taketake o te rama tiriti pūngao-rua 30W he 480N. Ina whakaarohia te tauwehenga haumaru o te 1.3, ko te F=1.3 × 480 = 624N.
Nō reira, M=F × 1.545 = 949 × 1.545 = 1466N.m。
E ai ki te tātaitanga pāngarau, ko te ātete ātete o te mata rahunga toroidal W=π × （3r2 δ+ 3rδ2+ δ3）。
I te tātai i runga ake nei, ko r te diameter o roto o te mowhiti, ko δ te whānui o te mowhiti.
Moma parenga o te mata rahunga W=π × （3r2 δ+ 3r δ 2+ δ 3）
=π × （3 × waru rau whā tekau mā rua × 4+3 × waru tekau mā whā × 42+43）= 88768mm3
=88.768 × 10-6 m3
Te ahotea i puta mai i te wā mahi o te kawenga hau i runga i te mata rahunga = M/W
= 1466/（88.768 × 10－6） =16.5 × 106pa =16.5 Mpa<<215Mpa
Ko te 215 Mpa te kaha piko o te maitai Q235.
Me tutuki te ringihanga o te turanga ki ngā whakaritenga hanga mō te rama rori. Kaua rawa e tapahi i ngā kokonga, kaua hoki e tapahi i ngā rauemi hei hanga i tētahi turanga iti rawa, ki te kore ka kore e pumau te pokapū taumaha o te rama tiriti, ā, ka ngāwari te maka atu, ka puta he aituā haumaru.
Ki te nui rawa te koki piko o te tautoko rā, ka nui ake te ātete ki te hau. Me hoahoa he koki whaitake, engari kaua e pā ki te ātete hau me te tere hurihanga o te mārama o te rā.
Nō reira, mena ka tutuki te whānui me te matotoru o te pou rama me te hononga whakarewa i ngā whakaritenga hoahoa, ā, he tika te hanganga o te turanga, he tika te piko o te waeine rā, kāore he raruraru o te ātete hau o te pou rama.
