Description

Technical Field

[0001] This invention belongs to the field of tumbling finishing technology, specifically relating to a calculation method and system for energy transfer and dissipation in vibratory polishing. Background Technology

[0002] Energy transfer in vibratory polishing mainly involves two processes: First, the vibrating body interacts with particles within its amplitude range, inputting external energy into the particulate medium. This energy is then transferred within the particles and further acts on the workpiece surface. The particulate medium induces micro-wear on the workpiece surface through a combination of collisions, compression, and friction. Therefore, material removal from the workpiece surface in vibratory polishing is the result of external energy being transferred to the particulate medium and converted into mechanical forces on the workpiece. After energy is transferred from the vibrating body to the particulate medium, inelastic collisions and friction within the microscopic dense particle flow and between particles and the vibrating body lead to energy dissipation. This energy loss is mainly manifested in macroscopic phenomena such as particle breakage, vessel wall wear, and temperature rise in the particulate medium flow. Quantitative characterization of energy transfer and dissipation within the particulate medium group is crucial for accurately determining the amount of material removed from the workpiece and achieving high surface integrity.

[0003] However, existing research on vibratory polishing particle flow mainly focuses on describing the macroscopic particle flow field, mesoscopic force chain network, and microscopic contact behavior, lacking in-depth exploration of the microscopic energy transfer and dissipation mechanisms inside the particle flow, and these characteristics are difficult to directly observe and analyze through experiments.
