The generator frame is the main load-bearing component in generator set. The generator frame consists of assembly of the parts of generator like generator, electrical equipment, accessories, etc. The generator frame must be strong enough to with stand the torque and vibrations loads generated by the generator. The generator frame is mostly made by welded steel plates and bolted connection, so it is complex in structure and cannot be calculated by applying theoretical formula in strength of materials. For this reason, we need to utilize the finite element method to make calculation by means of engineered software. In this project we have considered a generator has a weight of 180Kgs with a production capacity of 10KW.This generator weight of 180kgs is applied as static load on the generator frame. As the generator considered in this project has lot of movable parts, it is subjected to huge vibrations. So, the generator frame is analyzed to check whether it will withstand for these vibrations caused by generator. Computer Aided Engineering (CAE) package is used to perform the analysis. In the present days, CAE package is widely used for different analysis in various fields. In this project a 3D model of the generator frame is done in NX-CAD and is converted into parasolid. This parasolid file is imported into ANSYS to perform finite element analysis. Structural static analysis is performed with a generator weight as static load, and stresses and deflections are documented. In these project dynamic characteristics of the generator frame is also evaluated by performing modal analysis to calculate natural frequencies of generator frame. Spectrum analysis is preformed to check structure behaviour for random vibrations. Efforts are made to optimize the design for the above said conditions. NX-CAD software is used for generating 3D model and ANSYS software is used for doing finite element analysis.
