Virtual Simulation On The Brv630-ga Hydraulic Steering Gear Operational System Of12,000DWT Bulk Carrier

With the rapid development of China’s economy and foreign trade increased every year,making ports increasingly busy.Ship construction began to develop in large-scale and high-speed.This put forward a higher requirement for the ship sailing’s security and economy. To keepshipping safe and economical, it needs ships follow route accurately. In the process, handlingsteering gear constantly to ensure the course. Then,how accurate the steering gear is operateddirectly affects the performance of the ship’s following. The accurate operation of the ship’ssteering can be trained. So, building a steering operational simulation system to train workers thecapacity. Turning ship’s course begins at the rudder’s rotation. When the rudder turning a certainangle, the hull will turn the same angle by the cooperation of rudder, hull and main engine powersystem. The simulation system can analyze the steering gear’s and hull’s matching. Currently thesupporting equipment manufacturing capacity of Chinese shipbuilding industry lags behind theentire hull manufacturing capacity. If creating a simulation platform to study marine equipmentperformance, it will be not only economical and efficient, conclusion and process of the researchshould be more intuitive, even guiding the purchase of ship equipment in some respects, but alsowill promote the marine equipment manufacturing. Although there are many scholars havestudied the ship steering simulation, most are concentrating on the track and heading control,however few referring the steering gear’s mechanism.And the researches usually separated thesteering gear movement mechanism from the hull’s.Virtual simulation experiments can ignore the limits of physical experiments, human andmaterial elements,personal safety. Furthermore, it has a better human-computer interactionsimulation results. Last but not least, it can validate the experiment data effectively. Thereforechoosing the virtual simulation research means based on the factors above in this paper.Putting the12,000DWT bulk carrier from engineering and its brv630-ga hydraulic steeringgear as research subjects, setting simplified conditions of the ship’s movement and the outsideenvironment. To set up ship’s and steering gear structures’ motion mathematical models andthree-dimensional models.Researching into the principles of steering gear’s operation.Simulatingship’s zig-zag maneuverability tests. Making use of virtual simulation platform VRP to establishsteering operation simulation scenes,combined writing a dialog procedure with MFC,getting thesteering operational simulation system. Details as follows: Firstly, simplifying interference and other conditions of navigation. Selecting theappropriate modeling method to establish mathematical model of ship movement.Secondly, introducing brv630-ga hydraulic steering gear’s structures and characters,building the mathematical model of main parts. Describing the Zig-zag ship maneuverabilitytests’s process and significance.And then, establishing the steering operational simulation scene of virtual environment byvirtual reality platform VRP and3D MAX softwares.Finally, getting regression formula of ship maneuverability index’s dimensionless value bystatistical software. Predicting ship’s maneuverability from theory and simulation. To illustratethe steering gear in this paper meets the basic requirements of ship’s steering gear throughcalculating. Under VC++environment, developing MFC dialog-based procedure, building up thesimulation system as expected..This system demonstrates the turning of the brv630-ga hydraulic steering gear from12,000DWT bulk carrier and hull’s turning. Realizing visual simulation of Zig-zag maneuverabilitytests.
