Farg'ona Politexnika Instituti
Ko'rsatilgan maqsadga erishish uchun quyidagi masalalar o'rganilgan va tadqiq etilgan:
1. Transport vositasi shinalari to'g'risida to'liq ma'lumot olish va ularni tahlil
qilish.
2. Shinalar ekspluatatsiya muddati va yeyilish intensivligiga ta'sir qiluvchi omillarning asosiy guruhlarini aniqlash va tasniflash.
3. Korxonada mavjud bo'lgan shina bosimini maxsus jihozlar va qurilmalar yordamida kuzatish va nazorat qilish tizimlari ishlab chiqish.
4. Shinalar ekpluatasion umrini omillarning o'zgarishi darajasiga qarab modellashtirish va monitoring tizimidan foydalanishning iqtisodiy samarasi va ekologik xususiyatlari.
"Farg'ona Sam Avtotex Servis" kompaniyasi turli xil harakatlanuvchi tarkibdan foydalanadi, deyarli har bir avtobus markasi nafaqat o'zining shinalari hajmidan, balki o'z brendidan ham foydalanadi, bu avtobus bilan birga kelgan, hali xizmat muddatini o'tamagan shinalar bilan izohlanadi. . Kelajakda sotib olish bitta brendga qisqartiriladi, bu hozirda ko'pcxilikni tashkil qiladi. Albatta, bitta markali shinalar va avtobuslarning eng katta guruhi bo'yicha tadqiqotlar o'tkazish maqsadga muvofiqdir. Ayni paytda eng keng tarqalgan avtobuslar ISUZU NP 37 va ISUZU HD 50, eng keng tarqalgan Boto rusumli shinalari 124/120K16PR Boto (butun mavsum).
"Farg'ona Sam Avtotex Servis" turli markadagi va yurgan masofadagi avtobuslarning katta parkidan foydalanadi, ammo ishda Boto shinalari ishlatilgan avtobuslarning markalari ko'rib chiqiladi. Harakatlanuvchi tarkib, uning yurgan yurishi va ishlab chiqarilgan yili 1.2 va 1.3-jadvallarda, asosiy texnik xususiyatlari 1.4-jadvalda keltirilgan.

Og'irlik yuki shinalar yeyilish intensivligiga ta'sir qiluvchi omil bo'lgani uchun, ushbu omilga ta'sir qiluvchi avtobuslarning xususiyatlarini ko'rib chiqamiz.

avtobus yo'lovcxilarga to'liq yuklanganda, avtobuslarning massasi yanada taqqoslanadigan bo'lishi.
Shinalarning ishlashi va chidamliligi
Avval aytib o'tganimizdek, kompaniya Boto rusumli shinalarni ishlatadi, ularning xususiyatlari 1.5-jadvalda keltirilgan.

Xabar qilingan ma'lumotlarga ko'ra, ushbu ishlab chiqaruvchining 621 ta shinalari tahlil qilindi. Sinovdan o'tgan shinalarning aksariyati notekis yeyilishga ega (notekis vositalar, bu holda, yelka va o'rta protektor zonalari orasidagi farq) - 57% (1.10-rasm), shinalarning atigi 30 foizida bir xil va boshqa turdagi yeyilish va zarar quyidagilarni o'z ichiga oladi: bo'ylama shish-0,6%; bo'ylama yeyilish-0,6%; bo'ylama yorilish-0,6%, shnurning yeyilishi-0,3% va shnurdan protektorning ajralishi-7,2%.
1.8-rasmda shinalar umrining umumiy populyatsiya (621 ta shinalar) bo'yicha empirik taqsimotining gistogrammasi ko'rsatilgan bo'lib, u 11 ta intervalgacha bo'lingan, har bir intervalning uzunligi 15127 km. 1.8-rasmdan ko'rinib turibdiki,

Umumiy populyatsiyani statistik baholash juda qiyin (621 ta shinalar), shuning uchun namuna parametrik bo'lmagan usul yordamida aniqlandi.
