Drop test bench and dynamic calibration method for undercarriage load measurement in load test flight

The invention relates to a drop test bench and a dynamic calibration method for undercarriage load measurement in load test flight, and belongs to the technical field of flight tests. The drop test bench comprises a frame, a lifting system, an undercarriage mounting table, two pairs of undercarriage mounting bases and a force measuring platform. The lower end of the lifting system is fixedly connected with an undercarriage mounting table; the lower end face of the undercarriage mounting table is provided with supporting columns of the undercarriage through a pair of undercarriage mounting bases, and supporting rods of the undercarriage are mounted through the other pair of undercarriage mounting bases; the force measuring platform is used for measuring the impact load of the undercarriage. 本发明涉及落震试验台及载荷试飞中起落架载荷测量的动态标定方法，属于飞行试验技术领域。落震试验台包括：框架、提升系统、起落架安装台、两对起落架安装底座、测力平台；框架内安装提升系统，提升系统下端固连起落架安装台；起落架安装台下端面通过一对起落架安装底座安装起落架的支柱,通过另一对起落架安装底座安装起落架的撑杆；测力平台用于测量起落架冲击载荷。
