wedge manometer

Planar inelastic stability of tapered columns,axially and eccentrically loaded,are studied with the proposed equations respectively.

在已有的楔形单元弹性刚度方程的基础上 ,推导了它的弹塑性增量刚度方程 ,并利用所得到的结果研究了轴心和偏心楔形压杆在强轴平面内的非弹性稳定 ,得到了各种楔率下楔形压杆的柱子曲线和轴力 弯矩相关曲

A new wedge pressing process for compressing large scale porous tubular preforms was adopted based on the idea of accumulating local small deformation as to integral forming.

基于多道次局部小变形累积致整体成型的工艺思路,采用一种新型的楔形压制工艺,对大尺寸Al-Fe-V-Si耐热铝合金喷射沉积管坯进行有效致密化,压制出尺寸为douter330mm×dinner314mm×78mm及douter330mm×dinner312mm×113mm的力学性能良好、整体均匀致密、外形圆整的耐热铝合金管材,并对楔形压制的致密化规律及其合金的组织与性能进行研究。
