摘要
Abstract
Rolling-moment measurement at micro level is extremely important for wind tunnel testing.Compared to conventional force tests,micro-rolling-moment measurement test is charac-terized by small rolling moment loading whose value of quantity is below 0.5N·m,and an obvi-ous difference between rolling moment load and other aerodynamic loads in the value of quantity. It is a great challenge to design a six-component strain gauge balance of appropriate structure for that purpose.To solve this problem,efforts were made to optimize the balance structure and the concept of composite six-component balance was developed and realized,which has reduced the measurement deviation (Δmx0<1.1 ×10-6 )and has addressed the configuration contradictions. In this paper,key techniques and primary technical measures for the newly-designed balance are introduced,with an account of the results of balance analysis and calculation,static calibration and test measurements.关键词
