Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] exist figure 1 In the embodiment, the system mainly consists of three parts: (i) drilling simulation and testing system; (ii) data acquisition system and (iii) data analysis system. The drilling simulation and testing system consists of a pulse generator, a pressurizing mechanism, a pulse shaper, a switching valve, a momentum trap, an experimental rod, a sample and a sample loading chamber, and a rotating mechanism. The pulse generator is composed of a pressure generator, a voltage regulator, a trigger switch and a pulse emission tube. The pressure generator is a pressure source for generating compressed air, driven by 220V alternating current. An impact rod is installed in the pulse emission tube, which forms an impact rod system together with the experiment rod, shaper, conversion valve and momentum converter. The pulse generator triggers the...

Abstract

The present invention provides a boring dynamics simulation test system. The boring dynamics simulation test system is formed by boring simulation and test, data collection and data analysis and is configured for the simulation of impact, rotation and rotation-impact boring processes and enforcement of dynamic characteristic test under the action of material impact, rotation and rotation-impact. The boring dynamics simulation test system realizes measurement of parameters such as axle load, impact rate, drill speed, drilling rig torque, impact energy and the friction coefficient and the frictional force between the drill bit and the rock, the drilling rod vibration and the like. The material dynamics response system can perform dynamics response test such as material intensity, dynamic friction and the like in the impact, rotation and rotation-impact load in the pressure contact, non-pressure contact and non-pressure and non-contact conditions. The boring dynamics simulation test system can be applied to each drilling system and drilling parameter and material dynamics response characteristic test of impedance materials in the conditions of different impacts and rotation rates.
