【摘要】：以蛇怪蜥蜴为仿生对象,基于蛇怪蜥蜴股骨旋转带动两脚踏水的高速运动行为,设计了水面仿生矢量推进器,增加了驱动力输出维数,实现了可控的托举力、推进力和转矩输出。结合RNG k-ε湍流方程和PISO算法,构建推进器的流体动力学模型,获得了叶片径向和轴向的最优设计形状,推导了驱动力与叶片长度和宽度的数学函数。最后,搭建矢量推进器试验系统,验证了数值计算模型的正确性;进行两栖车辆样机试验,矢量推进器驱动车体实现了10.6°仰角状态的滑水航行,为水面装置减阻提速提供了一种新思路。
[Abstract]:Taking the snake monster lizard as the bionic object, based on the high speed movement behavior of the snake monster lizard driven by the rotation of the thigh of the snake monster lizard, the surface bionic vector thruster is designed, which increases the output dimension of the driving force and realizes the controllable lifting force, propulsion force and torque output. Combined with RNG k-蔚 turbulence equation and PISO algorithm, the hydrodynamic model of thruster is constructed, the optimal design shapes of blade radial and axial are obtained, and the mathematical functions of driving force and blade length and width are derived. Finally, the test system of vector thruster is built to verify the correctness of the numerical calculation model, and the prototype test of Amphibious vehicle is carried out, and the driving body of vector thruster realizes water skiing in the state of 10.6 掳elevation angle, which provides a new idea for reducing drag and increasing speed of water surface device.
