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 ...
