Embodiment Construction
[0040] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and a preferred embodiment.
[0041] The maximum load of the pneumatic shock response spectrum testing machine in this embodiment is 200kg, the size of the resonance plate (length×width×height) is 600mm×500mm×40mm, and the weight is 135kg. The size of the hammer head (length×width) is 800mm×500mm. The hammer head is made of forged aluminum, with a weight of 200kg. The inner cavity diameter of the hammer head is 160mm, and the maximum movement stroke is 350mm. The main technical indicators that can be achieved are:
[0042] 1) Inflection point frequency: adjustable from 100 to 1500Hz;
[0043] 2) Maximum shock response spectrum peak value: 35000m / s 2 .
[0044] For testing machines with smaller load requirements, the quality of the hammer head and the diameter of the inner cavity of the hammer head can be reduced. If greater excitation force...
