摘　　要：为反映轮盘动力源试验器的实时工作状态和气动性能,排气系统流量调节装置应尽可能接近试验件的出口。文中设计了一种在轮盘试验件出口处设置环形通道排气流量的调节装置。通过改变压缩气体的流通面积和试验件的排气流量,调节该试验器在工作范围内特定转速下的工作状态,满足了动力源的试验需求。To reflect the real-time working state and aerodynamic performance of the wheel power source tester,the flow control device of the annular channel of the exhaust system is required to be as close as possible to the outlet of the test piece.This paper studies a regulating device for the exhaust flow of annular channel at the outlet of the wheel test unit.By changing the flow area of the compressed gas and the exhaust flow of the test part,the working state of the tester under the specific speed in the working range can be adjusted to meet the test demand of the power source.
