Redundant-drive shaking tables composed of more than one shaking tables are indispensible test equipments for anti-seismic study of long-span structures and are experiencing rapid development recently. However, the control strategy of the shaking tables system is greatly complex and there isn't a common accepted method now. This paper proposed two degree of freedom(DOF) control strategies for the...
Driving simulators are largely employed in automotive industry, government, military and academic research fields. This paper provides an overview of the development of a kind of special amphibious vehicle driving simulator. A modularization structure was developed according to the structure character, maintainability and fixing space requirement which provide a kind of convenient methods to replace...
In this paper, an analysis of the principle of the shaking table is carried out and a digital servo-valve controller for three-axis six-DOF shaking table based on TMS320F2812 is designed. The result was compared with the analogue controller. AD598 is selected as the modulator-demodulator to condition the displacement signal of the servo-valve main spool.AD7665 is adopted to acquire the conditioned...
The use of simulation for research and engineering enables to evaluate new aircraft designs, equipment or concepts in an realistic environment. But the required time, cost and complexity to create or reuse simulations often limits their application. This paper describes the design of the hardware and software architecture for the COTS base reconfigurable flight simulator in an affordable manner. More...
Flight simulator is among the most sophisticated software systems in existence. It is highly distributed, has rigorous timing requirements, and must be amenable to frequent updates to maintain high fidelity with the ever-changing vehicle and environment it is simulating. We proposed an optimized distributed real-time simulation framework to facilitate the high fidelity flight simulator research. It...
