歼击机特殊部件设计载荷谱编制技术

介绍了用飞行模拟仿真法编制新机设计载荷谱的技术途径和特点.重点阐述了整体油箱压力/应力谱和垂尾阵风侧滑机动谱等歼击机特殊部件设计载荷谱编制技术.整体油箱载荷谱编制的关键在于各种载荷状态的压力计算,还应考虑地-空-地循环.垂尾谱不能完全由飞行模拟获得,而必须以空测统计数据为基础.

Loading Spectra Development for Special Structural Members of Fighter

The approach and specialties of loading spectra development using maneuvers simulation technique for new design aircraft were introduced in brief. On the above basis, the approach and key points of developing stress/pressure spectrum for integral tank, gusts and sideslip spectrum for vertical tail were presented in detail. One key step of developing stress/pressure spectrum for integral tank is to calculate the pressure of the tank in all loading cases, and the G A G cycle should be taken into account for the analysis spectrum of the tank. The loading spectrum of the vertical tail is obtained by not only the simulation of maneuvers but also some statistical measurements.
