力同轴度自动检测技术研究

Research of Load-Coaxiality Testing Technology

叙述力同轴度自动检测技术 :基本假设、计算模型的建立及数据处理方法 .根据计算模型设计了自动测量系统 ,用 3支光栅式引伸计和数据转换器 ,能直接实时测量力同轴度和偏心方向 ,不仅具有很好的适用性 ,还具有一定的工程应用前景 .

An automated method for measuring load coaxiality of universal testing machine was presented in two aspects: basic hypothesis, math modeling for calculating and processing. Based on the principle the modeling concept was proposed. From the models posed, a measuring system using computer testing technology had been designed,which used three raster strain sensors as well as digital converters and it can measure the load coaxiality and direction directly in real time. The method holds strong adaptation and applied foreground in engineering.
