Physical Design of an Automatic Measuring Instrument for the Flatness Error of the Rail Wagon

The automatic measuring instrument for the flatness error of the rail wagon is designed with carbon fiber and aluminium alloy, which makes the instrument handy with good stiffness. After the design for the main structure and arranging the position of sensing element, finite element analysis is used to guarantee that deformation of structure itself will not affect the measurement accuracy. The design of the automatic measuring instrument for the flatness error of the Rail wagon takes the place of tradional feeler gauge measurement, raised the work efficiency and improves the measurement accuracy to 0.1mm.

Dynamic Link

Matlab and Microsoft Visual C++ were used to program the automatic measuring instrument for the flatness error of the Rail wagon. Microsoft Visual C++ is used to program the struct body, which takes full advantage of the high programming efficiency, high execution speed and beautiful imple interface. In the meantime, powerful computational function and image fitting of Matlab is added to the program. Through the method of Dynamic Link Library, these two softwares are linked and the figure created by Matlab can be insetted in the main interface created by Microsoft Visual C++, which keeps the united and elegant appearance.

Photosynthesis And Respiration

Carbon dioxide is the very important material of plants when they are making food by means of photosynthesis. The concentration of carbon dioxide restricts photosynthesis and respiration in a dose-dependent manner. Therefore, keeping stability concentration of carbon dioxide is quite important for plant to grow rapidly. This paper mainly introduced the system composition and working principle of carbon dioxide automatic measuring instrument, the system taking Freescale MCU as control core. The instrument can collect signal, display data and reset by connecting with the PC. The experiment result states clearly this carbon dioxide automatic measuring instrument has practical value and application significance.
