Brake buffer recovery test device

The utility model belongs to the technology field of spaceflight ground test recovery, and concretely relates to a brake buffer recovery test device. The device comprises a steel rope, a roller, a brake mechanism, and a base. One end of the steel rope winds the roller, and the other end is connected with a separation body to be recovered. The brake mechanism is installed at the two sides of the roller, and installed on the base. The base is fixed on the ground. The device is first used in a booster separation test, overcomes the recovery difficulty of separation bodies with large size, great mass, and high impulse, and greatly saves the development expenditure and period of model tasks. The device can start recovery via a control system, can be triggered to perform recovery in a passive way, can complete recovery action in a shorter time, can guarantee safety and stable recovery of recovery bodies in a recovery process, and is advantaged by simple device and little occupied space.
