Ikki tasmali shina mexanik hisobi

5.5.4. Ikki tasmali shina mexanik hisobi
Agar har bir faza ikki tasmadan bajarilsa, unda tasmalar va fazalar orasida kuchlanish hosil bo‘ladi. Tasmalar orasidagi kuchlanish bir- biriga tegmasligi lozim. Ushbu kuchlanishni kamaytirish uchun tasmalar ustunlari orasiga qistirmalar joylashtiriladi. Ustunlar orasi qistirmalar orasida qisqa tutashishda hosil bo‘ladigan elektrdinamik kuchlar tasmalar to‘qnashuviga olib kelmasligi uchun lp tanlanadi:
(48)
Ikki tasma mexanik sistemasi – izolyatorlari 200Gs dan ortiq bo‘lgan shaxsiy tulqin chastotasiga ega bo‘lishi lozim, mexanik rezonans tufayli kuchlanish ko‘payib ketmasligi uchun. Shunga asosan lp ifodasi yana bir shart bilan tanlanadi
(49)
bunda ap – tasmalar o‘qi orasidagi masofa, sm; Jp=hb3/12 – tasmalar inersiya momenti, sm; kF – forma koeffitsiyenti; mp – uzunlik birligidagi tasma massasi, kg/m; E – shina materialining qayishqoqlik moduli.
Yuqorida ko‘rsatilgan ifodalardan aniqlangan ko‘rsatkichlarning hisob uchun ikki ko‘rsatkichdan kichigi olinadi.
Ikki tasmalar paketidagi tasmalar o‘zaro ta’sir kuchi ushbu ifoda orqali topish mumkin i1=i2=iz/2; a=ap=2b ni qo‘yib:
(50)
Tasmalar o‘zaro ta’siridan shina materialidan kuchlanishi, MPa,
(51)
bunda Wp – bir tasma qarshiligi momenti, sm3; lp – qistirmalar orasidagi masofa, m.
Fazalar o‘zaro ta’siridan shina materiali kuchlanishi quyidagicha
(52)
bunda l – izolyator ustunlari orasidagi masofa, m; WF– shina to‘plami qarshilik momenti, sm3.
Shinalar mexanik mustahkam, agarda hisob = F + p rux.
