Abstract EN
Vibration isolation systems are widely employed in automotive, marine, aerospace, and other engineering fields.
Accurate input forces are of great significance for mechanical design, vibration prediction, and structure modification and optimization.
One-stage vibration isolation system including engine, vibration isolators, and flexible supporting structure is modeled theoretically in this paper.
Input excitation acting on the vibration isolation system is reconstructed using dynamic responses measured on engine and supporting structure under in-suit condition.
The reconstructed forces reveal that dynamic responses on rigid body are likely to provide more accurate estimation results.
Moreover, in order to improve the accuracy of excitation reconstructed by dynamic responses on flexible supporting structure, auto/cross-power spectral density function is utilized to reduce measurement noise.
