Изобретение относитс , к области технической физики и предназначено дл  измерени  усилий на аэродинамические модели или их элементы при испытани х в аэродинамических трубах.The invention relates to the field of technical physics and is intended to measure the force on aerodynamic models or their elements when tested in wind tunnels.

Известные многокомпонентные тензовесы обладают недостаточной точностью измерени  усили , так как в них на датчик дл  измерани  продольного усили  оказывают вли ние деформации в неизмер емых ими направлени х.The known multicomponent tensses have insufficient accuracy in measuring the force, since in them the sensor for measuring the longitudinal force is affected by the deformation in the directions that they do not measure.

Дл  повышени  точности измерени  усилий Б предлагаемых тензовесах центр жесткости трех датчиков , установленных в одной плоскости , расположен в центре их симметрии и находитс  на оси жесткости остальных трех датчиков параллельных между собой.In order to increase the accuracy of measuring the forces B of the proposed tenses, the center of rigidity of three sensors installed in one plane is located at the center of their symmetry and is located on the axis of rigidity of the other three sensors parallel to each other.

На фиг,1 схематически изображены описываемые тензовесы в трех проекци х; на фиг,2 - схема их деформации,Fig. 1 shows schematically the described tensives in three projections; Fig, 2 - scheme of their deformation,

Тензовесы содерхат основание ITenzewesy content base I

соединенное с платформой шестью однокомпонентныыи датчиками силы 3-8, Датчики 3,4 и 5 параллельны между собой, а датчики ь,7 и В расположены в ортогональных к ним плоскост х через упругие шарниры. При этом центр жесткости датчиков 6,7,8 расположен в центре их симметрии О и находитс  на оси жесткости . датчиков 3,4,5,connected to the platform by six one-component force sensors 3–8, sensors 3,4 and 5 are parallel to each other, and sensors 7, and B are located in planes orthogonal to them through elastic hinges. In this case, the center of stiffness of sensors 6, 7, 8 is located at the center of their symmetry O and is located on the axis of rigidity. sensors 3,4,5,

Устройство работает следующим образом.The device works as follows.

Обычное наличие шести св зей обеспечивает статическую определимость системы, а кинематическое разделение только точно в недеформированном состо нии.The usual presence of six links provides static definability of the system, and the kinematic separation is only accurate in the undeformed state.

На фиг,2 приведена схема деформации весов от действи , например , где О - концы датчиков в недеформированном состо нииFig. 2 shows a diagram of the deformation of the scale due to the action, for example, where O is the ends of the sensors in the undeformed state.

( , закрепленные на основании I; О - смещенные концы датчиков от действи  My , закрепленные на платформе 2,(fixed on base I; O - offset ends of sensors from action My fixed on platform 2,

Следовательно, взаимовли ние каждого датчика Судет иинимальньш, если центр жесткости датчиков 6, 7,8, установленных в одной плоскости , расположен в центре их сиыыетрии и находитс  на оси жесткости параллельных между собой датчиков jTjS ПРЕДМЕТ ИЗОБРЕТЕНИЯ Многокомпонентные тензовесы. содержащие основание, соединенное однокомпонентными датчиками силы, три из которых параллельны, а три других расположены в ортогональных к ним плоскост х, отличающиес  тем, что, с целью повышени  точности измерений усилий, центр жесткости трех датчиков, установленных в одной плоскости, расположен в центре их симметрии и находитс  на.оси жесткости трех других датчиков.Therefore, the mutual influence of each Sudette sensor is minimal if the center of stiffness of sensors 6, 7.8 installed in the same plane is located in the center of their strength and is located on the axis of rigidity of the jTjS sensors parallel to each other. OBJECTIVE OF THE INVENTION containing a base connected by one-component force sensors, three of which are parallel, and three others are located in planes orthogonal to them, characterized in that, in order to increase the accuracy of force measurements, the center of rigidity of three sensors installed in one plane is located in the center of them symmetry and is on the axis of rigidity of the other three sensors.
