1. COMPUTER AIDED ENGINEERING (CAE)• One of the fundamental features of Engineering is to make trade-offs to get optimal designs • If we overdesign, then all designs become simple, but more expensive, and more difficult to manufacture • If we underdesign, then our design will not fulfill our requirements • Therefore we use knowledge and tools to achieve designs which are ‘just right’. • There are many physical factors which can affect the quality of a design, - Resonance at wrong frequency - Electromagnetic interference effects - Non uniform cooling effects (eg. warping in plastic parts) 1.1 FINITE ELEMENT ANALYSIS (FEA)1.2 ASSEMBLY AND KINEMATICS1.3 ASSEMBLIES1.4 OPTIMIZATION |
