What Is Dynamic Spin Testing?
Leave a CommentJet engine and gas turbine designers must understand the dynamic behavior of bladed rotors and devise a means to manage their resonant vibrations. The dynamic behavior of bladed rotor can be very complex and could result in incipient fatigue failures. The blade vibrations can be influenced by several variables, including its geometry, manufacturing tolerances, material, […]
The Value of Fatigue Testing
Leave a CommentFatigue testing is a crucial procedure used by engineers and technicians to help predict the durability of a part or component under its operating conditions. To appreciate the value of fatigue testing, it is essential to first understand the phenomenon. Fatigue is a type of structural damage prevalent in cyclically loaded structures. The fatigue is […]
