[ 1 ] - Measurement and Modelling of the Rubber Resilience based on Ultrasonic Non-destructive Testing in Tires
In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...
[ 2 ] - Modeling of Weld Bead Geometry Using Adaptive Neuro-Fuzzy Inference System (ANFIS) in Additive Manufacturing
Additive Manufacturing describes the technologies that can produce a physical model out of a computer model with a layer-by-layer production process. Additive Manufacturing technologies, as compared to traditional manufacturing methods, have the high capability of manufacturing the complex components using minimum energy and minimum consumption. These technologies have brought about the possibi...
[ 3 ] - مدلسازی سختی تایرها برپایه سرعت انتشار امواج فراصوتی طولی با استفاده از رگرسیون فرآیند گاوسی
آزمون‌های غیرمخرب، از قابلیت شناسایی عیوب و بررسی خواص قطعه بدون تغییر خواص قطعه، برخوردار می‌باشند. آزمون غیرمخرب فراصوتی در پژوهش‌های بسیاری برای مطالعه ویژگی‌های مختلف مواد از قبیل خواص مکانیکی و ساختاری، مورد استفاده قرار گرفته است. از سرعت انتشار امواج فراصوتی به شکل گسترده‌ای در اندازه‌گیری سختی فلزات استفاده می‌شود. در پژوهش حاضر برای اولین بار از روش غیرمخرب آزمون فراصوتی برای بررسی سخت...
[ 4 ] - Application of the Extreme Learning Machine for Modeling the Bead Geometry in Gas Metal Arc Welding Process
Rapid prototyping (RP) methods are used for production easily and quickly of a scale model of a physical part or assembly. Gas metal arc welding (GMAW) is a widespread process used for rapid prototyping of metallic parts. In this process, in order to obtain a desired welding geometry, it is very important to predict the weld bead geometry based on the input process parameters, which are voltage...
