چکیده

Residual stress is a kind of stress which remains in mechanical components even after removing external forces. Residual stress mainly happens during production process of a component which in result affects significantly its design and performance. The standard ASTM E837-01 analyzes residual stresses in components with flat surfaces using drilling method and presents stress calibration coefficients with constant stress profile. However, there is not any special standard to measure residual stress in curved component utilizing drilling method. In this study, the considered model which is a vehicle rim is simulated first; then a dynamic analysis is done under road load profile using ANSYS software and the critical points of the specimen are determined; in the next step, residual strain measurement test is performed using central drilling based on the standard; after calculating residual stresses experimentally, some suggestions are presented to reduce adverse residual stresses and enhance component’s life.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
