|
摘要
根据某风洞实验室的要求设计了一种振动翼栅,运用SolidWorks软件建立了振动翼栅的三维模型。采用拉格朗日法建立了振动翼栅的动力学方程,得到电机力矩的函数方程。基于ADAMS虚拟样机对机构进行动力学仿真。并用MATLAB软件对动力学模型进行分析得到力矩的函数曲线,其与仿真得到的结果一致,说明了动力学模型的正确性和机械结构设计的合理性。基于MATLAB软件分析得出电机输出最大力矩的条件,计算出最大力矩,选择电机参数,完成控制系统设计。完成样机实验,机器运行良好。
An oscillated airfoil was designedunder specific indicators,and the three-dimensional model of the oscillated airfoil was established by using SolidWorks. The dynamic equation of the oscillated airfoil was established by using Lagrange method and obtained the motor torque equation.The dynamic simulation of the mechanism was carried out based on ADAMS virtual prototype. Analyzing the dynamic model to get the torque curve in MATLAB,the curve was consistent with the simulation results which showed the correctness of the dynamic model and the rationality of the mechanical structure design. The maximum torque of motor output under different operating conditions was calculated in MATLAB and using the maximum torque to select the motor parameters. At last the control system was established and the machine ran well in the prototype test.
