In this paper, a new kind of multiple-point loading test machine is designed for the scaling-down mode of architecture components. And it is designed by the control algorithm of the single neuron self-adaptive PID, and the PC software is designed by the graphics language-LabVIEW. Resolved the defects of existing test machines-huge volume, large energy consumption, system complexity, through the simulation...
In this paper, the structure of the coal mine pneumatic-driven gunite system was shown, the working principle of pneumatic hydraulic system was analyzed; the dynamic characteristic of the gunite material in the screw propeller was also analyzed in detail. The study to the pressure, flow rate and torque or power is very helpful to the designing of the machine. The conclusion can be obtained that benefit...
