Maqolada texnologik mashina va qurilmalar, shuningdek, teri hamda mo‘ynaning teri to‘qimasini silliqlash va yakuniy pardozlash texnologiyalarining tizimlashtirilgan sharhi keltirilgan. Abraziv materiallardan to‘liq foydalanishni hisobga olgan holda charm va mo‘yna yarim tayyor mahsulotlariga ishlov berishni ta’minlaydigan silliqlash mashinasi ishlab chiqilgan. Ishchi barabanda silliqlash varaqlarini ag‘darish va tez almashtirish imkoniyati mavjudligi tufayli teri xomashyosining turi va xususiyatlariga qarab silliqlash jarayonini optimal rejimda olib borish uchun sharoit yaratiladi. Bundan tashqari, silliqlash barabaniga ega mashinaning geometrik, kinematik va boshqaruv parametrlarini oqilona asoslash uning iqtisodiy samaradorligini oshirish va ekspluatatsion ishonchliligini ta’minlashga xizmat qiladi. Ushbu ishda teriga ishlov beruvchi barabanli silliqlash mashinasining ishchi barabani mustahkamligi tahlil qilingan. Baraban sifatida yuk ta’sirida aylanuvchi silindrsimon val qaraladi. Terini silliqlash jarayonida baraban sirtiga ishqalanish kuchlari va ayrim hollarda notekis taqsimlangan yuklar ta’sir qiladi. Baraban doimiy ravishda aylanish rejimida ishlaganligi sababli uning devorida aylanish natijasida hosil bo‘ladigan markazdan qochma kuch, teri bilan kontakt bosimi, baraban o‘qiga uzatiladigan yuklar ta’sirida yuzaga keluvchi egilish hamda val orqali uzatiladigan moment sababli burilish kuchlanishlari vujudga keladi. Shu sababli barabanni murakkab mexanik tizim sifatida tahlil qilish zarur. Tayyorlangan silliqlash barabani bo‘yicha o‘tkazilgan hisobiy-nazariy tadqiqotlar shuni ko‘rsatdiki, aylanish chastotasi \(n=1200\) ayl/min va o‘rtacha hisobiy radius \(r=0.145\) m bo‘lganda aylana yo‘nalishidagi normal kuchlanish taxminan \(2.61\) MPa ni tashkil etadi. Hisoblash modelini chegaraviy holatda tekshirish shuni ko‘rsatdiki, aylanish mavjud bo‘lmaganda \(\omega \to 0\), aylana kuchlanishi nolga intiladi. Shuningdek, kuchlanish material zichligiga chiziqli, burchak tezligi va radiusga esa kvadratik bog‘liqligi aniqlangan. Olingan hisoblash natijalari qabul qilingan analitik modelning tayyorlangan silliqlash barabani parametrlari bilan mosligini tasdiqlaydi.
