The invention provides an aircraft modal test free boundary simulation unit and simulation system. The aircraft modal test free boundary simulation unit comprises a supporting mechanism with a bearing cross beam and at least one first suspension mechanism slidably connected to the bearing cross beam; the sliding direction of the first suspension mechanism is parallel to the length direction of the bearing cross beam; the first suspension mechanism comprises a suspension assembly for suspending test pieces, a height adjusting assembly which is assembled and connected with the suspension assembly and is used for adjusting the suspension height of the suspension assembly, and a horizontal adjusting assembly which is assembled and connected with the height adjusting assembly; and the horizontal adjusting assembly is slidably connected to the bearing cross beam. According to the aircraft modal test free boundary simulation unit provided by the invention, the horizontal position and the height position of the suspension point can be adjusted, so that the suspension requirements of the suspension test pieces at different positions can be met, then free state modal tests can be carried out on aircrafts with different structural sizes, and the aircraft modal test free boundary simulation unit has good universality.

    本申请提供一种飞行器模态试验自由边界模拟单元及模拟系统,飞行器模态试验自由边界模拟单元包括具有承重横梁的支撑机构以及可滑动连接在承重横梁上的至少一个第一悬吊机构;第一悬吊机构的滑动方向平行于承重横梁的长度方向;第一悬吊机构包括:用于悬吊试件的悬吊组件、与悬吊组件装配连接用于调节悬吊组件悬吊高度的高度调节组件、以及与高度调节组件装配连接的水平调节组件;水平调节组件可滑动连接在承重横梁上。本申请提供的飞行器模态试验自由边界模拟单元可以调节悬吊点的水平位置和高度位置,从而可以满足不同位置悬吊试件的悬吊需要,进而可以对具有不同结构尺寸的飞行器进行自由状态模态试验,具有良好的通用性。
