OPTIK TOLALI SENSORLARNING EKSTREMAL SHAROITLARDA ISHLASH BARQARORLIGINI OSHIRISH VA MEXANIK SHIKASTLANISHLAR VA UZILISHLARNING OLDINI OLISH TEXNOLOGIYALARI
Keywords:
Optik tolali texnologiyalar so‘nggi o‘n yilliklarda jadal rivojlanib, an’anaviy elektr va pyezoelektrik sensorlarga nisbatan o‘zining qator fundamental afzalliklarini namoyish etdi. Ularning elektromagnit xalaqitlariga ta’sirchan emasligi, kichik o‘lchamlari, uzoq masofalarga signal uzata olishi hamda bitta tola bo‘ylab bir vaqtning o‘zida ko‘plab nuqtalardan ma’lumot olish (multiplekslash) qobiliyati ularni noyob o‘lchov vositasiga aylantirdi. Hozirgi kunda bu texnologiyalar aerokosmik soha, neft va gaz sanoati, shuningdek, ko‘priklar, to‘g‘onlar kabi yirik muhandislik obyektlarining strukturaviy yaxlitligini uzluksiz monitoring qilishda (Structural Health Monitoring - SHM) keng qo‘llanilmoqda.Abstract
Ushbu maqolada optik tolali sensorlarning (OTS) ekstremal sharoitlarda — yuqori harorat, kuchli mexanik bosim, tebranishlar va kimyoviy agressiv muhitlarda ishlash barqarorligini oshirish masalalari tahlil qilinadi. Optik tolalarning asosiy qismi bo‘lgan silikat shishasining mo‘rtligi ularning amaliyotda uzilishi va mikrobukilishlarga moyilligini keltirib chiqaradi. Maqolada mexanik shikastlanishlarning oldini olishga qaratilgan zamonaviy himoya qoplamalari, tolalarni qadoqlash arxitekturalari hamda signallarni yo‘qotishsiz qabul qilish texnologiyalari ko‘rib chiqiladi. Ishning asosiy maqsadi — murakkab muhandislik inshootlari va og‘ir sanoat obyektlarida optik tolali sensorlarning uzoq muddatli va ishonchli ishlashini ta’minlovchi muhandislik yechimlarini tizimlashtirishdan iborat.
