摘　　要：风速是气象、环保、工农业生产、建筑、军事诸多领域的基本测量参数。目前的风速测量仪受结构、原理、量程等因素制约,存在通用性较差的问题,特别不适合用于野外长期无人值守的自动气象站。该文基于风载荷原理,提出了一种基于多维力传感器的新型风速测量仪,它由2个正交的弹性应变梁组成,采用应变片测量弹性梁的风载荷,达到风速、风向测量的目的。与普遍使用的机械式风速仪相比,它没有运动部件,具有响应快、结构简单可靠、环境适用性强的特点,是一种极有发展前景的风速测量仪。Wind speed is an essential parameter in the field of meteorology,environmental protection,industrial and agricultural production,architecture,military affairs,and etc.Restricted by the factor of structure,principle,measuring range,etc,current anemometers can＇t be used in all kinds of conditions,especially at long-term unattended automatic weather station.Based on principles of wind load,this article refers a new idea of wind speed measuring instrument which depend on multi-axis force sensors.In order to measure the speed and direction of the wind,this instrument is made of a couple of orthogonal elastic strain beams,and adopts strain gauges to measure beams＇ wind load.Compared with wildly used mechanical anemometers,it has the characteristic of fast response,simple structure,better environmental applicability and etc.The development of the new kind of wind speed measuring instrument should have good prospect.
