Optimization Design of Distribution Product Vibration Resistance Based on Modal Analysis

Blog Article

Vibration is an important load for the destruction of airborne electronic equipment, and circuit board components are the core components of electronic equipment.In the design stage of power distribution products, it is necessary to carry out dynamic analysis and anti-vibration bostik universal primer pro optimization design of circuit board.Based on the design of an airborne power distribution product, the MSC.Patran and MSC.Nastran softwares are used to conduct modal analysis and vibration analysis of the product structure, and the natural frequency and vibration response curves of the product are obtained.

Based on modal analysis, different optimization schemes are proposed for modeling and modal analysis.The results show that the vibration resistance of the products can be improved by increasing the thickness of the circuit remtavares.com board, reasonably arranging the components on the circuit board, flanging the stiffeners, and adding screw restraint at the easily deformed parts.
