| Abstract: | 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. |
