| 摘要: |
| 针对飞行器半实物仿真领域对电动作动器高精度建模的需求,对电动作动器的各分系统分别进行动力学方程描述,建立了含间隙、刚度和摩擦等非线性因素的完整电动作动器模型。通过对比模型仿真与实测结果,表明所建分系统的动力学方程是合理正确的。建立的模型对于指导作动器的设计和优化均具有较大的参考价值。 |

| Abstract: |
| In order to meet the demands of precision modeling of Electro-Mechanical Actuator in aircraft HILS areas,kinetic equations of subsystems in EMA are described respectively and a complete EMA model with nonlinear factorssuch as clearancestiffness and friction are established.The simulation and the experimental show that the kinetic equations of subsystems are reasonable and correct,and the model has great reference value for the design and optimization of EMA |
