A Layout Optimization Method of Dynamical Property Oriented by Parts and Component of Electronic Equipment

Based on condensation method of degree of freedom and component mode synthesis method, a component-oriented printed circuit board (PCB) dynamical property analysis method is built up, and then, a component-oriented PCB layout optimization method is presented. The optimum calculation program is developed based on the object-oriented secondary development method of ANSYS and modified genetic algorithm considering geometric interferences between components. Examples show this optimization method is a good way and available in engineering projects.
