Roundness Measurement

This article studies the embedded SPC and its application in roundness measuring system by analyzing the current roundness measurement principle and technology. With analyzing the process of data collection, date treatment and various kinds of tool graphic construction, we study the feasibility of integrating SPC into roundness measurement and finally apply the embedded SPC as pure software into roundness measuring system. We design the roundness measuring system based on embedded SPC and develop the roundness measuring system of low power consumption, high accuracy and easy application, which is suitable for industry field usage.

High Accuracy Measurement

With the development of measuring technology,the measuring accuracy of optical glass refractive index of the increasingly high demand,V prism refractometers is major general instrument for measuring the refractive index of optical glass,not only the simple device,convenient measurement,and this method has high precision performance,however,the accuracy is only attained ,which in the regulation of national metrology verification and the introduction of V prism refractometers in the literature,the classic formula calculation principle formula error caused by refractive index has more than .Based on the mechanical structure and optical transmission to improve the original V prism refractometers the refractive index of air,by considering the influence on measurement precision of V prism refractometer,to mathematical modeling of V prism refractometer the principle formula,V can be measured refractive prism refractometer rate accuracy increased to ,measurement repeatability less than ,has important practical significance for realizing high accuracy measurement of the refractive index of optical glass.

At present, the energy crisis is increasingly serious. Energy-saving becomes a practical issues faced by all fields in the life. Considering this, the paper presents a new vehicle consumption measuring system based on intelligent handling and humane design under the promise of accurate measurement as well as low cost. In addition, the use of radio frequency communication technology makes precise measurement of instant and accumulative fuel consumption come true in any working hours. Field experiment results show that the vehicle fuel consumption measuring system has character of facilitate operation, low cost, advanced and reliable measurement method and high accuracy (within 1.5%). It can improve greatly the production efficiency of the internal combustion machine and avoid effectively the waste phenomenon, and be prone to make further application widely.
