Wind-filed Simulation And Modeling Technology Of Harbor Simulate

With the continuous development of simulation technology, the wind-field simulation in the authenticity requirement is also increasing faster and fast, so the higher degree of the true simulation model has important practical significance. But now several wind-field models used very widely all have their flaws, while the little wind and high accuracy requirements of the case could not simulate good enough the wind-field simulation. for example,when sumulate environment wind-field of the hanbor. For this particular request, this use of wind farms based on particle system to simulate the wind-field, while the modeling environment to complete the design of the port in order to achieve the port environment simulation.In the study of the basic principles particle system and collision detection and the existed algorithms, analyzed the principle of particle collision detection system. Then designed the particles tree hierarchy based on bounding AABB collision detection algorithm. Then the particles in the force as a body for the wind-filed, and the collision with the particle as the force on an object method, proposed wind farm based on particle system models. The properties of particles through the design to build the right wind, the movement pattern of particles and particle collision detection of objects to determine the motion of an object, the establishment of the wind-filed based on particle system models. After the realization of the particle emitter and the AABB tree hierarchy based on bounding box of the particle collision detection algorithm, and combine them together to achieve the design of the wind-field model. And the design of the wind farm model and pressure commonly used model made the comparison in the harbor environment,indicating their respective advantages and disadvantages. Finally, the hierar- chical division of the harbor model, model drawing, model and model of the export assembly work, and the actual real-time harbor's data to read and write in memory the principles and themethods. The crane as an example of the memory data harbor equipme- nts are described and implemented the program in the three-dimensional objects picked up the mouse.Wind field model based on the particle environment in the port into graphic for the windpressure can achieve more realistic simulation results, for the simulation of future wind farms have some reference.
