The invention provides an anisotropic friction surface vibration feeding test platform. Four adjustable feet are installed at the four corners of the lower part of the bearing platform, a brake baffle is installed on one side of the bearing platform, and guide bearings and pressure plate supports are installed on both sides of the support plate. The impact plate is placed between the support plate, the guide bearing, and the horizontal guide bearing. There is no surface contact between the impact plate and the support plate. A feeding plate is installed on the top of the impact plate, and two A buffer return spring, the other side of the impact plate is in contact with the exciter, a through hole is opened in the center of the material cover plate, and a funnel is installed on it. It has a simple structure, small footprint, easy to adjust the height of the platform and the angle between it and the ground, easy to install and maintain, can separate a variety of parameters for research, good decoupling, external vibration exciter and equipped with buffer reset The spring can stabilize the vibration performance in the working space, and still have high dynamic response when subjected to high-frequency impact.

Description

technical field [0001] The invention relates to the field of material physical parameter test equipment, in particular to a vibration feeding test platform for anisotropic friction surfaces. Background technique [0002] The precise transportation of material particles can be achieved by using shock traveling waves. At present, this technology mainly uses piezoelectric drive devices to excite bending traveling waves of ultrasonic frequency on carriers such as slender catheters or flat plates. When traveling waves propagate in the carrier, The particles on the surface of the carrier make a microscopic elliptical motion, and the direction of motion at the top of the elliptical trajectory is opposite to the propagation direction of the bending traveling wave, thereby driving the material particles on the carrier surface to move in the opposite direction of the traveling wave. This technology requires a relatively complex control system and is not conducive to the transportation...

Problems solved by technology

This technology requires a relatively complex control system and is not conducive to the transportation of large quantities of materials. Therefore, a simple technical solution is proposed to complete the transportation of material particles by applying longitudinal impact by the mechanism. The surface of the transportation carrier used in this technology has an anisotropic friction surface Morphology, this shape can make the frictional resistance of the particles in the direction of movement smaller, and the frictional resistance of the opposite direction is larger, which can enhance the efficiency of particle transportation, and can realize the transportation of a large amount of materials without complicated control systems

However, the effects of impact parameters (excitation frequency, impact energy, amplitude, etc.), surface topography, normal pressure on the material, carrier inclination angle, and material type on the conveying efficiency have not been demonstrated, so it needs to be tested. Research
