Modern naval battle forces generally include many different platforms, e.g., ships, planes, helicopters, etc. The optimal assignment of radar jamming resources distributed over these platforms is an important research aspect of EW real-time decision support system. This paper presents the mathematical model of the radar jamming resources assignment of multi-platforms and proposes the assignment algorithm...
This paper proposes a smart control system to reduce ice-induced motions in the offshore jacket platform structure subjected to ice-induced vibration. Magnetorheological (MR) dampers are applied as smart control devices and the control input determination is based on a clipped-optimal control algorithm which uses absolute displacement and acceleration feedback. The performance of this method is studied...
Numerical simulation method is a powerful technique for chaos analysis. The traditional analytic method can't predict the behavior of the piecewise linear system (PLS) exactly because of the non-smoothness of the system, if the system is strong nonlinearity. The piecewise linear vibration isolation system with single degree of freedom (SDOF) was studied in this paper. The “inverse” integral method...
Operation system modeling is an important content of war research. However, operation system involves so many ingredients and relations that traditional modeling methods based on reductive theory can't describe the significance of information in the modern battle. Complex Network theory affords a new measure of complex system modeling from the point of whole network. Paper based on complex network...
We put forward a system structure of controlling the tightening operation of bolts using multiraxial tightening machine. A kind of fieldbus intelligent tightening control system is designed with the technology developing of fieldbus intelligent instrumentation. This system is a distributed structure based on fieldbus control system which consists of CAN bus, Profibus-DP bus, and adopts many advanced...

The optimization algorithms is one of difficult problems to be solved for ship shafting alignment which is multi-field coupling as statically indeterminate and flexible complex system, it is the key and focus question to evaluate and control ship shafting condition. In this study, a general optimization algorithms for ship shafting alignment to describe the transfer function is suggested and validated...
This paper analyzed and calculated electromagnetic field and counterbalance force between the permanent magnet thrust plate for a novel permanent magnet axial thrust balance structure in canned motor pump using a numerical method of Ansoft software. Then constructed permanent magnet axial thrust balance experiment device and detected the characteristics of repulsion and attraction which made up of...
The design method of Water Strider Robot (WSR) is discussed in the paper. A WSR prototype driven with two electric motors and tele-controlled via infrared signals is designed and successfully built. A set of algorithms for designing the size of the driving leg is also proposed. Moreover, the methods and an instance to design the structure, control system and software of the robot are present. With...
