The invention relates to the technical field of aerospace machinery, and discloses a multifunctional drop test device, which comprises a vertical test bed, and the test bed is provided with an energy storage release system, a drop system and a load acquisition system from top to bottom; the energy storage and release system is used for storing potential energy for the drop system and controlling and releasing the drop system, the drop system comprises an outer frame and an inner frame which can be separated, and the landing buffer device is fixed in the inner frame; the shock falling system is used for locking the landing buffering device, and after the energy storage releasing system releases the shock falling system and when the energy storage releasing system is away from the ground by a certain height, the outer frame is prevented from continuing to fall, the inner frame is unlocked, the inner frame and the landing buffering device continue to freely fall and collide and impact with the load collecting system by impacting the buffering support. According to the invention, the inner frame is unlocked before the drop system collides with the load acquisition system, the disturbance of the landing buffer device during unlocking is small, and the test reliability is high; and an anti-inclination single-leg or multi-leg drop test can be conveniently carried out.
本发明涉及航天机械技术领域,其公开了一种多功能落震试验装置,其包括立式的试验台架,试验台架自上而下设有储能释放系统、落震系统以及载荷采集系统;储能释放系统用于为落震系统储蓄势能并控制释放落震系统,落震系统包含可分离的外框架和内框架,着陆缓冲装置固定于内框架中;落震系统用于锁定着陆缓冲装置,并在储能释放系统释放落震系统后,距离地面一定高度时通过撞击缓冲支架阻止外框架继续下落,对内框架完成解锁,内框架和着陆缓冲装置继续自由落体,与荷载采集系统碰撞冲击。本发明的落震系统与载荷采集系统碰撞前完成内框架解锁,着陆缓冲装置在解锁时受到的扰动小,试验可靠性高;方便进行抗倾斜单腿或多腿落震试验。
