The invention relates to a passive vibration reduction and impact resistance device suitable for spaceflight electronic equipment, and belongs to the field of engine structure load environment tests. Comprising an upper vibration reduction module, two lower vibration reduction modules and electronic equipment, the electronic equipment is of a horizontally-placed cuboid structure. The upper damping module is fixedly mounted in the middle of the top of the electronic equipment; the two lower damping modules are symmetrically mounted at the bottoms of two opposite side walls of the electronic equipment; during a vibration test, the upper vibration reduction module and the two lower vibration reduction modules are in butt joint with an external vibration source, so that the vibration test of the electronic equipment is realized, and the vibration reduction of the electronic equipment is realized through the upper vibration reduction module and the two lower vibration reduction modules; the invention provides the vibration reduction and impact resistance device suitable for spaceflight electronic equipment, and provides a test method for examining the vibration reduction and impact resistance device on a ground test bed, so that the vibration reduction effect of the vibration reduction and impact resistance device can be fully verified in a ground test, and the risk of test run is greatly reduced.
