| 中文摘要: |
| 为了更真实全面地仿真航空发动机的使用状态，研制了一种用于小型航空发动机整机动态姿态仿真测试的台架。该台
架具有横滚和俯仰2个自由度，可提供位置、速率及摇摆等功能，采用伺服电机带动齿轮组件和蜗轮蜗杆进行驱动，并具备排气装
置。设计结果表明：动态姿态模拟转台速度可达30°/s，加速度可达50°/s2，运动范围为±175°，定位精度实测优于±0.12°；可以任何
位置为中心做正弦、梯形、三角波等形式的运动。该设备的研制可进一步提高地面试验的仿真精度，有利于发动机检测技术的发展。 |

| In order to simulate the use state of aeroengine more truly and comprehensively，a dynamic attitude simulation test platform
of small aeroengine was developed. The platform had two degrees of freedom of rolling and pitching，and could provide position，speed and
rocking functions. It used servo motor to drive the gear assembly and worm，and had an exhaust device. The design results show that the
speed of dynamic attitude simulator can reach 30°/ s. The acceleration can reach 50°/s2，the range of motion is ±175° and the positioning
accuracy is better than that measured ±0.12°. It can move sine wave，trapezoid wave and triangle wave at any position. The development of
the equipment can further improve the simulation accuracy of ground test and is conducive to the development of engine detection technology. |
