摘　　要：5.5 m×4 m声学风洞尾撑试验装置采用液压驱动,用来控制模型的迎角和侧滑角,具有4个自由度,是一个复杂的机电液系统。利用Motion/AMESim仿真平台对该尾撑系统进行了机电液一体化建模和联合仿真研究。结果表明:该尾撑系统可以实现模型姿态角的精确控制,满足设计要求。同时也说明Motion/AMESim仿真平台在风洞设计中具有广阔的应用前景。The 5.5 m × 4 m wind tunnel sting support mechanism is driven by hydraulic power and used to control the attack an- gle and yaw angle of model. It is a complex hydromechatronic system with four freedoms in all. Based on Motion/AMESim platform, the modeling and simulation of this sting support mechanism were studied. Results show that the support mechanism satisfies the design requirement. Results also show that Motion/AMESim platform has wide application and development foreground in the design of wind tunnel.
