二维波流共线作用下全直接法床面切应力测量仪设计研究
Study of designing measuring instrument with whole direct method for bed shear stress under two-dimensional water-flow collinear action
摘要
Abstract
The current study aimed at the design and making of measuring instrument of whole direct method for bed shear stress under two⁃dimensional water⁃flow collinear action. The instrument combined the traditional strain gauge with precise pressure gauge,and adopted direct measuring method of the difference between lateral hy⁃drodynamic pressure and differing head pressure on both sides of force plate. As a result,such an instrument solved a technical puzzle of the past strain gauge,i.e.,it is difficult to set apart shear stress and lateral force. Static force test and sink test both proved that the instrument is precise,stable and applicable to shear stress measurement of rough bed of various types.关键词
