从性能指标划分,我国测力仪的发展经历了三个阶段,下面介绍测力仪(环)各个阶段的发展状况。一、发展状况1.第一阶段测力仪(环)发展史的第一阶段是1950-1993年期间。在这个阶段,测力仪(环)基本是机械指针式测力环,其结构如图1所示。主要性能指标如下:(1)准确度:0.3%(2)测量范围:600N~3000k N(3)使用温度:-10℃~40℃;湿度:≤90%RH
Divided from the performance indicators, the development of dynamometer in our country has gone through three stages, the following describes the dynamometer (ring) in various stages of development. First, the development status 1. The first stage dynamometer (ring) the first phase of the history of the 1950-93 period. At this stage, dynamometer (ring) is basically a mechanical pointer type force ring, the structure shown in Figure 1. The main performance indicators are as follows: (1) Accuracy: 0.3% (2) Measuring range: 600N ~ 3000kN (3) Operating temperature: -10 ℃ ~ 40 ℃; Humidity: ≤ 90% RH
