The Computer Aided Design Analysis and Structural Optimization of Engine Accessory Components 870872

This paper describes the integration of computer graphics, finite element analysis including design sensitivity analysis, and structural optimization technology to automate the design analysis and design optimization of engine accessory components. By use of MSC/NASTRAN's design sensitivity analysis and structural optimization methodology, the design of vehicle components is facilitated to achieve both design improvement and a significant increase in engineering efficiency.The application of this technology to two typical engine accessory brackets for minimum weight design subject to constraints on stresses due to applied loads as well as natural frequencies is described.
