摘要:

本文论述了一种新型推力架,采用了整体弹性元件和座控自动校准系统。推力架具有高的固有频率和良好的动态响应。不仅用于稳态推力测量,而且也用于变推力测量。推力测量范围是0～500N,保证精度为0.3％。

Abstract:

A new type of thrust stand with solid elastic elements and telecontrol automatic calibration system is discribed in this paper.The thrust stand has high natural frequencys and good dynamic response.Not only is the thrust stand used for steady state thrust measurement, but it can also be used for measuring changeable thrust.The measurement range is 0-500N.The accuracy is about 0.3%.
