Численное моделирование гидроабразивной резки листовых заготовок из алюминиевых сплавов

Abstract

Приведена физико-математическая постановка задачи процессов гидро- и гидроабразивной резки деталей из листовых заготовок алюминиевых сплавов. На конкретном примере рассмотрены особенности решения поставленной задачи на базе численных методов механики сплошной среды и зависимость исследуемого вида обработки от кинематических и физико-математических свойств инструмента (высокоскоростной струи) и обрабатываемой детали (мишени). Проанализированы возможности использования деформационного критерия разрушения материала детали из алюминиевого сплава АМг6.

The paper covers the physical and mathematical problem formulation of water jet and abrasive water jet cutting operations of parts from aluminum alloys sheet billets. The features of the problem solution based on numerical methods of continuum mechanics and the dependence of this operation type on kinematic and physico-mechanical properties of the instrument (high-speed jet) and the workpiece (target) are shown by the particular example. Advantages of using the deformation criterion of the material failure (aluminum alloy AMg6) are discussed.
