本文以扭矩标准装置为研究对象,着重对如何精确施加力偶,尤其是如何精确施加竖直向上的力进行研究、试验,并对装置进行改装设计,达到减小装置的不确定度、提高准确度的目的。一、国内外研究现状国内外扭矩标准装置大都采用杠杆砝码式加荷原理:即在一定臂长的杠杆上,加挂一定数量的砝码形成标准扭矩值,从而实现扭矩量值的传递、校准及
In this paper, the torque standard device as the research object, focusing on how to accurately exert force couple, especially how to accurately exert vertical upward force research, test, and modification of the device design to reduce the device uncertainty and improve accuracy the goal of. First, the status quo at home and abroad Most of the standard torque devices at home and abroad using lever-type load principle: that is, in a certain arm length of the lever, plus a certain amount of weight to form a standard torque value, in order to achieve the transfer of torque values, Calibration and
