摘　　要：随着空气动力学研究的深入,风洞作为空中或者地面交通器的重要实验装备,在以交通器噪声指标为代表的科学研究和工程设计中发挥越来越重要的作用。高压变频器作为空气动力地面实验台主机的驱动设备,性能要求较高,主要体现在转速准确度、转矩响应和制动能力等方面。以风洞主机高压变频驱动装置研究为例,建立了风洞主机工况模型,通过升降速和惰转时间研究,提出了变频器单元能耗制动方案。基于以上工作的模拟实验验证了风洞主机变频器的技术可靠性,可作为相关产品制动系统方案设计的参考。With the deepening of aerodynamic research, as an important experimental equipment of air or ground vehicles, wind tunnel plays a more and more important role in scientific research and engineering design represented by vehicle noise index. With the deepening of aerodynamic research, as an important experimental equipment of air or ground vehicles, wind tunnel plays a more and more important role in scientific research and engineering design represented by vehicle noise index. As the driving equipment of the main engine of the aerodynamic ground testbed, the medium voltage driver has high performance requirements, which is mainly reflected in the speed accuracy,torque response, braking capacity and so on. Taking the research on the medium voltage driver of the main engine of the wind tunnel as an example, this paper establishes the working condition model of the main engine of the wind tunnel, and puts forward the energy consumption braking scheme of the frequency converter unit through the research on the lifting speed and idling time. The simulation experiments based on the above work verify the technical reliability of the wind tunnel host frequency converter, which can be used as a reference for the scheme design of the braking system of related products.
