Abstract

Mine ventilation parameters wireless tester which is based on ZigBee technology is proposed and designed according to the deficiencies of conventional ventilation resistance test method and mine ventilation resistance testing principle. The instrument is capable of simultaneously measuring between a certain range of two points of the temperature, humidity and barometric pressure in the roadway. And it can transmit test data by wireless to the main instrument. At the same time, the main instrument would display and storage the date for post-processing. The development of sensor technology,electronics and information technology and wireless communication technology make developing high-precision mine ventilation parameter analyzer for mine ventilation resistance test to be a reality.

Abstract

Flexible smart driving mechanism is a combination of a smart actuator and flexible elements. It is an important part of the smart structure, mainly used in precise positioning and vibration control. In such application the displacement (or thrust) output and the natural frequency of the mechanism are two important design parameters. In the paper it is presented at the first that the two technical parameters (the output and the frequency) couldn’t be designed independently. Then based on static and dynamic analysis the design method of a general flexible smart driving mechanism is given. As an application, the design of a fast steering mirror, driven by a flexible smart driving mechanism is given. To verify the result, an experimental study has been done. The consistency of theoretical and experimental result is obtained.

Abstract

Selected the typical loess landslide to analyze and calculate, adoption of elastic-plastic dynamic FEM and Drucker-Prager yield criterion, using Earthquake motion time-histories as the seismic input will be based on the fitting of , class standard response spectrum curve in the current seismic resistance design code. From the analysis of loess slope deformation and breach at different peak acceleration, spectral and duration, it shows the dynamic response and change rule of soil under earthquake effect.
