摘要:
为了研究高温密封组件金属弹簧性能,本文通过对波音公司编网状弹簧管结构和Streck心脏支架结构的研究,建立了编织弹簧的几何拓扑构型和数学模型,推导了弹簧直径计算公式。采用AUTODESK 3D-MAX构建了编织弹簧的仿真模型,用ANSYS仿真软件分别从编织丝直径、编织密度以及编织方法3方面探究不同测试对弹簧性能的影响。结果表明,增加弹簧丝直径、降低弹簧管轴向方向的编织密度、提高圆周方向的编织密度、向外的弹簧管编织方式可有效提高弹簧管的回弹性能。

Abstract:
In this paper, to study the metal spring properties of high temperature sealing components, a parametric model of braided spring tube was established based on the characteristics of the Boeing’s braided spring and Streck cardiac stent, and the spring diameter formula are deduced. AUTODESK 3D-MAX was used to simulate braid spring, the effects of spring diameter, density, and method are studied. The results show that increasing the diameter of spring wire, reducing the density of woven springs in the axial direction,increasing the circumferential density of woven springs, and the way of the spring tube which is woven outside can improve the elasticity of spring tube.
