B balanced construction 平衡型结构·纤维织物中经纱和纬纱相等。拉伸(或压缩)荷载在结构中只产生拉伸(或压缩)变形,弯曲荷载在纵向和横向产生相等的纯弯曲。 balanced design 平衡型设计·在纤维缠绕增强塑料中,使所有纤维的应力相等的一种缠绕线型设计。 balanced-in-plane contour 平面封头曲面·在纤维缠绕制品中,纤维束处于一个平面内,调整封头曲率半径使纤维方向的应力与压力载荷平衡的封头曲面。 B balanced construction Balanced structure · The warp and weft are equal in the fabric. Tensile (or compressive) loads produce only tensile (or compressive) deformation in the structure, and bending loads produce an equivalent pure bending both longitudinally and transversely. balanced design Balanced design - A wound-wire design that makes all fibers stress equal in fiber-wound reinforced plastics. balanced-in-plane contour In the case of fiber-wound products, the fiber bundle is in a plane and the head curvature is adjusted so that the stress in the fiber direction and the pressure load are balanced.
