Abstract
Maqola ipak torli an’anaviy dutorning lad tizimini menzura parametrlar hamda tarang tor mexanikasi asosida nazariy jihatdan qayta tiklash masalasiga bag‘ishlangan. Boshlang‘ich parametrlar sifatida ochiq tor uzunligi 1000 mm, D3 (146,83 Hz) chastotasi, ipakning zichligi 1300 kg/m3, Yung moduli 5 GPa, tor diametri 0,7 mm hamda torning xarrak yonidagi balandligi 6,67 mm qabul qilindi. Har bir parda uchun jaranglovchi qism uzunligi, torning parda ustidagi balandligi va 12-TET teng temperatsiya tizimiga nisbatan dastlabki geometrik farq hisobga olindi. Hisoblash modeli asosiy taranglikni aniqlash, bosilgandagi qo‘shimcha cho‘zilish miqdorini topish hamda taranglikdagi ortishni sentlarga aylantirish bosqichlarini o‘z ichiga oldi. Tadqiqot natijasida taranglik korreksiyasi odatda 3-5 sent oralig‘ida bo‘lishi va mustaqil holda soz turini shakllantirmasligi aniqlandi. Asosiy omil pardalarning joylashuvi bo‘lib, u teng temperatsiyaga emas, balki ayrim aralash xususiyatlarga ega bo‘lgan kvinta-pifagor tamoyiliga moyil an’anaviy notekis tizimni ko‘rsatadi. Shu tariqa, hatto sof nazariy model doirasida ham menzura geometriyasi hamda dinamik taranglikning yakuniy intonatsiyaga qo‘shadigan hissasini alohida ko‘rsatish mumkinligi isbotlandi.References
