  • Space particle suspension transport has the advantages to avoid adsorption loss, contact pollution, and signal interference, and has potential applications in the fields of cell self-assembly, controllable distribution of nanoparticles, and micro-Led mass transfer. Here, an ultrasonic array device was developed to obtain space particle levitation transport, and explore the suspension mechanism of the specific impact of the modulation signal on the space transmission and the mechanism of using the phase modulation signal to control the opposed linear transducer array to realize the space transportation. The suspension and directional transportation of ultrasonic standing waves are both non-contact and important means for processing without a certain container, and have a very broad application prospect in the fields of mechanical manufacturing, biochemical trace analysis, and droplet dynamics and so on. In this paper, aiming at the imperfect mechanism of space transportation and the complicated method of space transportation, we propose a new method of using phase modulation signals to control the array of opposite linear transducers to realize the space transportation of solid pellets. The transportation acceleration is used to characterize the stationarity in the transportation process, and the specific deviations of different phases of the modulation signal are set, so that the curves of acceleration change and position change of solid pellets in the transportation cycle can be drawn. The results show that when the phase deviation is π/2, it is the best to realize the stability of lateral transportation. When the phase deviation of coaxial array elements is set to π in longitudinal transportation, stable and long-distance transportation based on cycle period can be realized. The parametric model of 3D finite element is established, and the specific distribution of instantaneous sound pressure of dynamic sound field in space transportation is simulated. By comparing the experimental phenomena with different simulation results, we can find that the transportation process of solid balls is in good agreement with the movement of sound pressure nodes in sound field.
