Study on dynamical simulation model of shelter vibration isolation system

To study the dynamic characteristic of the vibration system of shelter, the ADAMS parametric dynamical simulation model of shelter vibration isolation system based on rigid-flexible hybrid base was established with multi-body mechanics and FEM. The isolation system was optimized by the mixed programming of ADAMS and ISIGHT, and simulation results of the optimized model show that the designed isolation system meets the requirements of the electronic equipment protection. The driving experiment was carried out, and the effectiveness is verified by the experiment.

Development of Experimental Chaos Identification Analysis System

It is an important task to identify chaotic vibration in nonlinear vibration isolation system chaotification experiment. However, the chaotic time series toolbox is provided in few traditional data analysis software. The experimental chaos identification analysis system is developed in this paper based on LabVIEW. It can be applied to measure and analyze vibration signal in time, and the time history, power spectrum and phase space diagram can be observed with this developed system. Furthermore, it can be used as different signal sources such as harmonic signal, pulse and chaotic signal. In order to check the effectiveness of this system, the experiment is carried out, and the period-1, period-2, and chaotic attractor are measured. The different attractors are compared, and the self-similarity structure of the chaotic one is shown.Copyright
