Shock analysis for structural robustness of induction motor is one of the important criteria for the qualification of any design for its application. High Shock can severely damage the functioning of the machine and even in medium range of shock cases can destroy the machine. Submarines & naval machines are expected to encounter such situation of high impact & shock load condition. Under such working condition, the induction motor structural robustness of naval machines plays a vital role. In this presented research work it is attempted to analyse structural robustness of naval machine part i.e Induction motor. The performance and reliability of induction machine under high shock load falls down drastically. The shock, which is an impulsive wave front under goes an initial dynamic acceleration followed by deceleration at different time periods induces severe stresses and deflections on different location of electrical machine such as static structure of stator and its foundation feet, DE (Drive end) and NDE (Non Drive End) end shield, shaft rotor system, and stator and rotor interface, can generate operational damage. The proposed work involves design investigation using finite element method on UG NX Model followed by ANYSIS Mechanical APDL and the result of this work gives the allowable stresses condition.
