Title: Numerical and Experimental Study of Electromagnetic Crimping
Language (ISO): en
Abstract: Electromagnetic pulse crimping is a solid state, high speed, and high strain rate joining process. In this process, the flyer is deformed over the base plastically to produce the joint. In this work, copper tube was crimped over the aluminium rod by using single step field-shaper. Finite element analysis, as well as experimental study, was carried out on the single step field-shaper to crimp the copper tube on the aluminium rod. The finite element model was validated based on the measured temperature and outer diameter of the crimped rod. The validated model was used to study the effect of the working length position on the electromagnetic crimping. The variation in the working length position of the field-shaper was analysed to increase the concentration of the electromagnetic pressure at the desired location to produce an effective joint with better mechanical strength. It was found that with the change in the position of the working length of the field-shaper the impact velocity, temperature gen-eration, magnetic field density, and uniformity in crimping of the tube also changes.
