In this paper, a research and development version of the computer-aided system of mass tensometry (SMT) for conduction of aircraft and rocket-space equipment vibration tests is considered. A technique of the system design and development that combines the advantages of the system and process approaches when using the modern element base around the high-performance integral microcircuits is a distinctive feature in this research and development problem solution. We describe the architecture and structure of the advanced computer-aided SMTs and present data on its basic components desigtn. Also determined are the list and functional parameters of ratio-measuring network modules as well as the scheme of their connection to the test object and the local computer network of the enterprise. 相似文献

One-dimensional MHD simulations of solitary sharp and strong disturbances (impulses) of the interplanetary magnetic field and plasma of the homogeneous solar wind were performed. The characteristics of a disturbance of this type, recorded onboard the WIND spacecraft (SC) rather far from the Earth, were taken as initial conditions. The results of numerical experiments simulating the evolution of this disturbance in the moving interplanetary plasma, whose parameters correspond to observations of the WIND and INTERBALL-1 SC, show the efficiency of the computer code developed with the special purpose of investigating low-frequency wave events in the space environment. The calculated characteristics of the impulse resulting from the evolution are in good agreement with parameters of the disturbance recorded by the INTERBALL-1 SC closer to the Earth. In particular, the impulse expands due to imbalance of thermal and magnetic pressures, but keeps its abrupt boundaries. It was demonstrated that stable plasma objects, corresponding to stationary MHD solutions, could really exist in the solar wind plasma for a long time. 相似文献
