Vibratory response 100Hz) greatly reduces.The acceleration responded in a second direction d 2 is even less than 10% encouraged.In low frequency
Section, the amplitude of the wave crest of vibratory response are also reduced.Such as the amplitude of the corresponding response wave crest of vibrational excitation of 2g does not surpass in Fig. 3
Cross 0.5g.
The ambient vibration that curve L71 is 0.5g in Fig. 4 encourages curve, and the ambient vibration that curve L81 is 1g encourages curve, bent
The ambient vibration that line L91 is 2g encourages curve.Curve L72 is the vibration response curve of 0.5g in Fig. 3, and curve L82 is shaking for 1g
Dynamic response curve, curve L92 are the vibration response curve of 2g.It follows that built-in industrial computer provided by the invention, phase
For traditional structure, the corresponding frequency of wave crest of vibratory response is reduced, that is to say, that reduce the intrinsic frequency of system.Ring
Border vibrational excitation is bigger, and the reduction of intrinsic frequency is also bigger.In this way, built-in industrial computer is in high frequency stage (such as 60-
Vibratory response 100Hz) greatly reduces.The acceleration responded on third direction D3 is even less than 10% encouraged.Such as Fig. 4
The amplitude of the corresponding response wave crest of vibrational excitation of middle 2g is no more than 0.5g.
