MINING AND CONSTRUCTION MACHINERY ACTUATORS IMPACT PROCESS ON THE DEVELOPED GEO-ENVIRONMENT SOLID MASS STUDY METHOD

摘要

FIELD: construction; mining.;SUBSTANCE: invention relates to the mining and construction, is used for the mining and construction machinery actuators parameters remote registration and measurement in the process of their impact on the developed geo-environment, applied in the laboratory and field studies. Method comprises the actuators vertical and horizontal movements recording by the digital video camera using the vertical and horizontal movements at least one fixed mark. Then transferring the record video to the electronic data processing unit (hereinafter – the unit), where by means of the “mySize” software or its analogues, at least one measuring scale is installed into the recording video file and from the unit screen in the displayed record video file performing the fixed mark elements linear dimensions measurements, then determining the scale factor k_m as the ratio of the fixed mark actual linear dimensions and its image from the unit screen linear dimensions. By the record video file, using the fixed mark determining the actuators resource characteristics by the said measuring scale. Obtained data is transferred to the calculation and analysis module (hereinafter – module) of the unit and with its help, taking into account the scale factor k_m, determining the actuators movement rates actual indicators. Using the “MB-Ruler” software or its unit analogues by the recording video file determining the actuators embedding angle α and the f_rot frequency of their rotation during the fixed mark movement time relative to these actuators axis of rotation. Impact effects frequency f_imp after its recording by the digital video camera audio recording device is determined from the video recording file using the said unit acoustic signals processing audio software. Results of the f_imp and f_rot determination are transferred to the module of the unit and using it to determine the actuators angle of rotation γ between the impact loads. Calculating the developed solid mass one linear meter driving producing costs C, by results of which in the unit module performing the actuators impact process technical and economic efficiency analysis.;EFFECT: possibility of these actuators dynamic parameters remote permanent monitoring during the entire working cycle with the obtained data subsequent processing for the mining and construction machinery performance evaluation, measuring equipment set simplification with reduction in the ongoing research cost and their safety improvement.;9 cl, 2 tbl, 5 dwg
