Abstract

The invention discloses an establishment method for an ultrasonic power supply power adjustment model of an ultrasonic-assisted processing acoustic system. The method includes the specific steps that firstly, the theoretical relation between parameters related to the amplitude of the ultrasonic acoustic system and the amplitude is theoretically analyzed based on an amplitude-parameter relational expression and ABAQUS finite element simulation harmonic response analysis; secondly, an ultrasonic-assisted processing amplitude test experiment platform is designed and built based on theoretical analysis, the single-factor influence and comprehensive influence of the parameters on the amplitude are analyzed through the control variable method, and sample data is acquired; thirdly, regression analysis and optimization are conducted on the sample data through the multiple linear regression analysis method by means of the MATLAB, and then a guidance model with the amplitude as the dependent variable is established; fourthly, reverse deduction is conducted based on the guidance model with the amplitude as the dependent variable to obtain the ultrasonic power supply power adjustment model of constant-amplitude output of the ultrasonic-assisted processing acoustic system; fifthly, any pointed tool is selected to conduct experimental verification on the ultrasonic power supply power adjustment model.

Description

Technical field [0001] The invention relates to a modeling method of an ultrasonic power supply power adjustment model of a constant amplitude output of an ultrasonic auxiliary processing acoustic system. Background technique [0002] The honeycomb composite material has many advantages such as high specific strength and high specific stiffness, high temperature resistance, insulation and non-flammability, and is widely used in aerospace, automobiles, ships and construction fields. However, due to the orthogonal anisotropy of its structure, the high-efficiency and high-quality processing of honeycomb composite materials has become a bottleneck for its wider application. The introduction of ultrasonic-assisted processing technology into the processing field of honeycomb composite materials can effectively solve the problems of serious dust pollution, low processing efficiency, and low surface quality of processed parts in traditional milling processing. According to the fracture ...
