摘要

根据新飞机的要求，设计了一种骨架式仪表支撑结构，采用有限元法建立了仪表支撑结构的有限元计算模型，并对其承载能力进行了分析。通过分析计算结果，对结构刚度进行优化。利用金属增材制造技术，在充分考虑产品实现的前提下，采用新的粉末和粉末输送技术实现制造，使其满足飞行过程中过载、长时间低频振动的要求。

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.
