In this research, a numerical model of an explosive resistant flywheel in form of a glued spiral steel strip is presented and simulated. The model is set up parameterized to represent many design possibilities. These parameters are material parameters (Young's modulus and Poisson's ratio of steel as well as adhesive) and geometry parameters (number of turns, inner and outer diameters, and aspect ratio of steel and adhesive). The mechanical behavior of the flywheel was investigated. Six critical eigenfrequencies in the range of about 30 Hz to 90 Hz were identified. An additional contact model reveals that the detachment of the adhesive in only one spiral arm results in a complete breakdown of the structure. Hence, critical operational parameters of the flywheel are revealed, which is a major step toward reliable industrial development."}],"title":"Simulation of an Explosive Resistant Flywheel Energy Storage Device Based on a Steel Strip Spiral"}
