Abstract

Abstract

An electromagnetic loading system is designed to be applied to a separate Hopkinson rod experimental device. It can overcome the shortcomings of traditional pneumatic drive and achieve the purpose of accurately controlling the incident stress. The low-voltage loading method is determined through the investigation of electromagnetic loading technology, then the system equivalent RLC loop is constructed, and the functional relationship between the loop parameters and the incident stress wave is derived. Combining theoretical calculation results, using finite element software for coupling field simulation, the simulation shows that the number of turns of the active coil has a great impact on the pulse width and amplitude of the incident stress. At the same time, to ensure the utilization efficiency of electromagnetic energy, it is necessary to ensure that the thickness of the inductive coil is greater than the depth of magnetic penetration, and determine the parameters of the electromagnetic loading system according to the experimental requirements. An experimental platform was built to carry out the Hopkinson bar impact experiment, and the correctness of the theoretical calculation and software simulation was verified through the measurement of the incident stress.
