The installation slider can move in the T-shaped installation slot of the installation platform to adjust the fixed position of the suspension system on the installation platform. The installation platform is divided into a movable installation platform and a fixed installation platform. The movable installation platform is used for drop test in a temperature shock environment, the upper surface is provided with a T-shaped locking groove, and the lower surface is provided with a T-shaped installation groove, which are respectively used for locking the installation platform and installing the suspension launching device, and can meet the stability and reliability requirements of different types of suspension launching device assembly. The fixed installation platform is used for fixed point drop test, and the upper and lower surfaces are provided with the same as the movable installation platform. Before use, the movable installation platform is removed, and then the fixed installation platform is installed on the load-bearing frame outside the test box through a screw rod, so that the drop test of the suspension launching device in a normal temperature, high and low temperature and humid heat environment can be realized. The movement system is composed of a movement guide rail, an adjusting rod, a winch, a PLC controller, a guide pulley, a compensation device, a laser displacement sensor and a follow-up reflection end.

The hard position limiting device is installed with a hydraulic buffer at the end of the track corresponding to the design limit position of the movement installation platform. The front end of the impact head is made of rubber buffer material. When the soft position limiting device fails, the hard position limiting device can still realize the stop of the movement installation platform at the specified position through the energy absorption characteristics of the hydraulic buffer, effectively preventing the damage of the mechanism caused by hard collision.

[0024] The transfer trolley comprises a load-bearing frame, a blocking beam, a handle, a pulley, a ground rail, and a positioning foot cup. The transfer trolley moves on the ground rail through the pulley.

The entire detachable cover plate area can meet the 400KG bearing requirement, and can realize the operation and activity of about 6 people standing on the cover plate, which significantly improves the stability and safety of the operation. High-strength buffer materials are arranged in the buffer groove, which can withstand the impact force of 1500kg simulation objects falling from a height of 4m at an initial speed of 5m / s under the action of gravity acceleration. The material has excellent energy absorption and low resilience, which can effectively reduce the secondary bounce height when impacted by the simulation bomb, so as to quickly restore the simulation bomb to a stationary state, thereby protecting the simulation bomb and the test device. The elevator is an indoor fixed hydraulic elevator, which can realize the vertical transportation and specified height launching of the simulation bomb in the buffer groove, and adopts a scissor type lifting structure and an electric hydraulic system, so as to have high bearing capacity, stability and safety.

Oil medium is injected into the hydraulic chamber from the oil injection nozzle by an oil pump, the clamping ring is lifted by pressure, the disc spring is elastically deformed, the clamping sleeve is released, and the actuator plunger rod can move up and down freely. After pressure relief and oil discharge by the oil pump, the disc spring releases the elastic potential energy and rebounds on the clamping ring, thereby extruding the clamping sleeve and clamping the actuator plunger rod in place.

[0029] It should be noted that the annular piston can ensure the air tightness between the hydraulic cavity and the disc spring chamber, effectively prevent mutual penetration between the chambers, and ensure the safe and reliable operation of the locking device. Hydraulic oil is injected into the hydraulic cavity from the oil injection nozzle by the oil pump, the clamping ring is lifted and pressed, the disc spring is elastically deformed, thereby releasing the clamping sleeve, and the actuator piston rod can freely move up and down. After pressure relief and oil discharge by the oil pump, the disc spring releases the elastic potential energy rebound effect on the clamping ring, thereby extruding the clamping sleeve, so that the actuator piston rod is clamped in place, which can effectively prevent the piston rod from falling due to hydraulic system failure.
