Abstract

Hinge moment balance as a force measuring element is widely used in the wind tunnel test of hinge moment.The size of the hinge moment balance is limited by the installation environment and is generally small and mostly sheet-like structure. When the connecting end of the sheet-like structure is connected to the model body or the rudder surface, contact deformation and contact stress will occur at the connecting surface. This contact stress will affect the balance. The measurement has an impact.In order to study the influence of the structural parameters of the hinge moment balance on the output of the balance, the finite element calculation method combined with orthogonal experimental design was used to analyze the influence trend of the change of the fixed end of the hinge moment balance on the output of the balance under normal force loading. The research results show that the thickness of the fixed end of the chip hinge moment balance, the contact area and the position of the connecting screw involved in the orthogonal experiment have significant effects on the output of the hinge moment balance. Among them, the contact area of the fixed end of the hinge moment balance has the greatest influence, followed by the position of the connecting screw, and the thickness of the fixed end of the hinge moment balance has the least influence.

Key words： hinge moment balance; orthogonal test; finite element analysis; structure parameters
