description The invention discloses an integrated direct-drive type dynamic negative pressure generating device and an assembling method and application thereof, and belongs to the field of near space aircraft semi-physical atmospheric environment analogue simulation. The direct-driven dynamic negative pressure generating device based on the variable volume principle is realized through the integrated innovative design of the connection relation among the components such as a springback type displacement sensor, an air cylinder piston, a piston rod, a voice coil motor coil rotor and a voice coil motor magnetic steel stator, the voice coil motor is used as a control element, a piston assembly is directly driven to translate, and the direct-driven dynamic negative pressure generating device is realized. And the volume of the controlled cavity is reduced or enlarged, so that the controlled cavity generates a dynamic negative pressure signal near the initial pressure. According to the invention, a dynamic negative pressure s
