摘　　要：本发明公开了一种确定均布载荷下预应力圆薄膜弹性能的方法：将半径为a、厚度为h、杨氏弹性模量为E、泊松比为ν、预应力为σ0的圆薄膜，在其周圈固定夹紧，并对其施加一个横向均布载荷q，那么基于这个圆薄膜轴对称变形问题的静力平衡分析，利用载荷测量值q，则可以准确确定出薄膜变形后的弹性能U。

主权项：一种确定均布载荷下预应力圆薄膜弹性能的方法，其特征是：将半径为a、厚度为h、杨氏弹性模量为E、泊松比为ν、预应力为σ₀的圆薄膜，在其周圈固定夹紧，并对其施加一个横向均布载荷q，那么基于这个圆薄膜轴对称变形问题的静力平衡分析，利用载荷测量值q，薄膜变形后的弹性能U可以由以下公式确定： $U = {(\frac{π^{3} a^{10} {cq}^{4}}{2 hE})}^{1 / 3} ψ (c),$ 其中ψ(c)为： $\{\begin{matrix} &psi关键词：法律状态：生效IPC专利分类号： G01N3/08var ShareData = new Array();
