飞机轮轴向力值测量系统的现场校准方法与研究

飞机轮轴向力值测量系统主要包括力传感器和计算机采集系统,它们不易拆卸也不能拆卸下来送到校准试验室进行校准,因此必须进行现场校准。由于飞机轮的外形轮廓类似于圆柱形,承受载荷的轮胎表面是圆弧形,并且有两个飞机轮同时向前滚动等原因,因此对飞机轮轴向力值系统的现场校准是非常有难度的。本文通过对飞机轮轴向力值测量系统的分析,根据它的特点,研究出一套V形块现场校准装置和校准方法,并对此方法的可行性进行分析。

A Field Calibration Method of Axial Force Measurement System of Plane Wheels

The axial force measurement system of plane wheels mainly include force transducers and computer collection system.It is not easy and not realizable to take the system down from the test-bed to the calibration lab for calibrating,so the field calibration is needed.Due to the figure of plane wheel being similar to column,the supporting-load thread being arc,and two plane wheels rolling at the same time and so on,it is very difficult to field-calibrate the axial force measurement system.According to the analysis at the characteristic of axial force measurement system,this paper expounds a V-shape-block equipment and the V-shape-block method for field calibration,and analyzes the feasibility of the method.
