“…Analysis of the electromagnetic launcher is conducted using a special code or commercial software based on the finite element method. [30][31][32] In this study, an electromagnetic system was designed using electromagnetic analysis software (Maxwell 3D, ANSYS Electromagnetics Suite 16.0). The solution type is selected as ''transient'' and the default mesh is applied to different parts.…”

An electromagnetic launcher can be used as an accelerator for yarn attached to a ferromagnetic projectile. As a result, yarn endures a specific amount of tension. In addition to the yarn variables and the type of weft insertion system, the parameters of the weft yarn accelerator strongly affect the weft yarn velocity, its tension, and consequently the fabric quality. An applicable model that can represent the relationship between input and output parameters of this weft insertion system is very useful for predicting the strike of the projectile. Therefore, in this research a 3D imitating launching model was developed by the finite element method. A coil electromagnetic launcher was employed. An experimental methodology using an image-processing technique was also utilized to measure the projectile velocity. Numerical results were compared with experimental results to verify the numerical procedure. A validated model can be a reliable tool to investigate the effects of many process parameters on the strike of the projectile and to optimize them. Therefore, the system parameters can be scientifically defined by this model to insert a weft yarn.

“…Furthermore, in a multi-stage acceleration system, the analytic solution is nearly impossible to get since the neighboring coils interact with the projectile in a complicated way. For this reason, analysis of multi-stage EIL is conducted by using a special code or commercial software based on the FEA method in many studies [11][12][13]. In this study, we designed a threestage EIL system by using electromagnetic analysis software (Maxwell 2D, Ansys Electromagnetics Suite 16.2) based on the FEA method.…”

Electromagnetic Induction Launchers (EIL) have been receiving great attention due to their advantages of noncontact between the coils and a projectile. This paper describes the modeling and design of 3-stage EIL to accelerate a copper projectile of 50 kg with 290 mm diameter. Our EIL consists of three independent driving coils and pulsed power modules to generate separate driving currents. To find efficient acceleration conditions, the appropriate shape of the driving coils and the position of the projectile have been calculated by using a finite element analysis (FEA) method. The results showed that the projectile can be accelerated more effectively as the gap between the coils is smaller; a final velocity of 45 m/s was obtained. The acceleration efficiency was estimated to be 23.4% when a total electrical energy of 216 kJ was discharged.
