摘　　要：为分析传统材料超高压压力容器笨重的缺陷,提出纤维缠绕超高压前混合磨料罐的设计方式。通过网格理论设计方法分析筒身段和封头段纤维铺层力学特性,计算出磨料罐筒身段及封头段缠绕纤维厚度及缠绕角。通过solidworks软件建立磨料罐三维模型,运用ANSYS软件对纤维缠绕超高压前混合磨料罐的有限元进行分析,分析其纤维铺层的主要应力、应变情况。优化磨料罐上罐口结构,并与传统结构磨料罐的结果进行对比分析。结果表明:相比于传统合金钢制成的超高压磨料罐,纤维缠绕超高压前混合磨料罐的质量减轻一半以上,提升了前混合磨料射流装置的便携性;优化上罐口结构后,纤维铺层的应力、应变数值变化更加稳定。In order to solve the heavy problem of the ultra high pressure vessel made of traditional material,and the design method of ultra-high pressure pre-mixed abrasive tank with fibre winding was proposed.Through the grid theory design method,the mechanical properties of the fiber layer in barrel section and the head section were analyzed,and the fibre-wound thickness and fibre-wound angle were calculated.The three-dimensional model of the abrasive tank was established by solid works software,and the finite element analysis was carried out by ANSYS software to analyze the main stress and strain of the fiber layer.After optimizing the structure of the upper jar of abrasive tank,ANSYS software was used to analyze and compare with the results of traditional structure.The results show that compared with the ultra high pressure abrasive tank made of the traditional alloy steel,the mass of the ultra-high pressure pre-mixed abrasive tank with fibre winding is reduced by half,which promotes the portability of pre-mixed abrasive jet device.After optimizing the structure,the changes in stress and strain of the fiber layer are more stable.
