在强度消散和涡核运动方面,本文将尾涡的消散和运动分为近场涡和远场涡两个阶段,提出一个近似的近涡消散模型来描述尾涡形成阶段强度的消散和涡核运动情况;在近地阶段,采用镜像涡方法一并考虑地面效应对尾涡形成、消散和涡核运动的影响,根据尾涡间距加大的程度来判断地面影响的强弱,较好地反映了地面效应对尾涡运动和消散的影响;在安全间隔方面,提出以抖动失速作为遭遇尾涡后改出过程的坡度角极限,根据输入的安全系数综合确定可接受最大坡度角,而不是简单地给出固定的最大坡度角或诱导力矩系数;最后依据所开发的仿真计算系统,对尾涡形成、消散、涡核运动、遭遇过程、安全间隔等参数的影响因素及影响程度也进行了计算分析和研究,包括大气湍流、层结特性、大气密度、前机机型参数、前机重量、前机速度、前机高度、后机速度、后机重量、后机高度、操纵性和稳定性、飞行员的反应时间、安全系数、飞机垂直和水平航迹保持能力等因素。
Real-time Simulation for Fish Locomotion Based on Biological Modal and GPU Acceleration;
基于生物模型和GPU加速的实时鱼类运动仿真
Due to the problems existing in current system of real-time simulation on fish locomotion, such as heavy calculation, high complexity and difficulty in real-time simulation on ordinary PC, a new real-time simulation method was raised based on biological model and hardware acceleration.
针对目前鱼类运动实时模拟系统计算量大、复杂度高、很难在普通PC上进行实时模拟等问题,提出了一种基于生物模型和硬件加速的鱼类运动实时模拟方法,该方法在对鱼类生物模型和运动进行分析的基础上,对鱼类进行模块化建模,同时对鱼的运动进行分解并设计了统一的鱼类运动函数,通过GPU进行并行加速处理,提高了算法的运算速度,实现了在普通PC上的鱼类实时运动模拟,并取得了较好的效果。
