A structural optimization design for new aircraft instrument support

According to the requirment of the new aircraft, a skeleton instrument support structure was designed, the finite element method was used to establish the finite element calculation model of instrument support structure and analysis carrying capacity. By analyzing the calculation results, optimize structural stiffness. By using metal additive manufacturing technology, taking full account of product realization, new technology of powder was used and powder delivery to achieve manufacturing, making it meet the requirements of overloaded and long time low-frequency vibration in flight process.
