MULTI-OBJECTIVE OPTIMIZATION AND ANALYSIS OF TRI-STABLE PERMANENT MAGNET ACTUATORS FOR VALVE APPLICATION

Tri-stable permanent magnet actuator (TPMA) has been widely used in industry.In this study, a new TPMA integrating a permanent magnet actuator and two centralizing disc springs is proposed for valve application.By taking the linear coefficient of force/stroke characteristic, startup force, holding force and response time as the optimization objecti

This paper presents a time-efficient numerical approach to modelling high explosive (HE) blastwave propagation using Computational Fluid Dynamics (CFD).One of the main issues of using conventional CFD modelling in high explosive simulations is the ability to accurately define the initial blastwave properties that arise from the ignition and consequ
