1.55- mu m fiber-optic transmission experiments for long-span submarine cable system design

To improve the reliability, real-time performance and maintainability of navigation system, an optical-mechanical-electrical integrative design method of the fiber optic gyro inertial navigation /beidou/odometer integrated navigation system is proposed. Based on the basic working principle of the integrated navigation system, design of system structure and signal connection are implemented. In the integrated navigation system, all-fixed-structure, instrument and system integrative design and modularization design are used. At last, the integrated navigation system is developed, north seeking test and vehicle test are carried out to demonstrate the validity of the referred system design.

Load Simulation

The structural comfort of long-span floor structure which setup stadium is studied in this paper. The measured spectrum is used to simulate human movement loads. All possible loads are considered and key parameters about structural comfort of the long-span floor structure are analyzed, and then, the comfort of athletes in match and audiences on the stadium stand are analyzed. The results show the vertical acceleration and natural frequency of structure are decreased approximate linearly with increasing of the slab thickness; take one engineering project for example, according to the method proposed in this paper, the different structural comfort control index should be adopted in sports field and audience stand, respectively. Comprehensive and system design references of load simulation, pre-stressed structure dynamic analysis, comfort performance index and control standards are offered in this paper for long-span pre-stressed steel floor structure project that used for stadium.
