Abstract

When a rotor comes a part, it results in flying fragments. The fragments are impacted and penetrated in electric machine casing. Containing failed parts in high speed electric machines can be a real safety concern. This paper presents an advanced method for dynamic analysis of high speed failed part penetration in machine housing, based on plastic deformation theory with dynamic corrections. A comprehensive dynamic plastic deformation model is introduced which can simulate plastic high rate distortion of failed part and electric machine casing. Governing equations are formulated and solved to obtain crater geometry in casing and penetration value. Analytical results show good agreement with experimental data.
