In this paper, fatigue tests were conducted on specimens of 2024 aluminum alloy welded joints before and after ultrasonic impact treatment (UIT). The test results show that UIT, the life significantly increased under identical stress levels (Δσ 200MPa, 175MPa, 150MPa, 125MPa), all reaching 10 7 cycles, indicating a substantial increase in limit specimens.Building these findings, new model for studying was employed, effectively integrating Continuous Damage Mechanics (CDM) theory with...
Abstract Traditional gyrocompasses, while capable of providing autonomous directional guidance and path correction, face limitations in widespread applications due to their large size, making them unsuitable for compact devices. Microelectromechanical system (MEMS) gyrocompasses offer a promising alternative miniaturization. However, current MEMS require the integration motor rotation modulation technology achieve high-precision north-finding, whereas conventional motors previous research...
Titanium alloys are difficult to machine using conventional metal cutting methods due their low thermal conductivity and high chemical reactivity. This study explores the new multi-channel discharge machining of Ti-6Al-4V silicon electrodes, leveraging internal resistivity generate potential differences for discharges. To investigate underlying mechanism, equivalent circuit model was developed a theoretical simulation carried out. Comparative experiments with copper electrodes under...
Abstract Titanium alloys are extensively used in aerospace and medical engineering owing to their exceptional mechanical properties biocompatibility. For a long time, the low thermal conductivity of titanium has made them difficult machine with conventional approaches. Electrical discharge machining (EDM) is nonconventional method for difficult-to-cut materials. However, it not possible achieve high-quality surface finish while simultaneously maintain high efficiency. This paper introduced...
PCD tools, especially curve edge compound tools are used widely in machining nonferrous and non-metal materials with high efficiency precision because of their excellent cutting properties. But quality grinding is the uppermost obstacle application there great difficulties to profile sharpen grinding, for milling cutter drill edge. This paper studied technology wire EDG by electrical discharge machine five-axis CNC system. The was evaluated scanning electron microscope (SEM) roughometer....
