摘　　要：基于应用现场安装空间的局限性问题和对微型化测力传感器的需求,通过Creo Simulate模块的有限元法设计了一款低外形、小量程的薄板悬臂梁式测力传感器。该测力传感器具有结构简单、强度高、应用方便等优点,可适合目前对低外形、小量程测力传感器的需求,利用合金钢材料制作了该测力传感器,并通过惠斯通桥路里应变片的不同组合方式,分析了不同组桥方式对测力传感器灵敏度输出大小的影响,以及不同组桥方式时灵敏度输出受偏载的影响。Based on the limitation of field installation space and the demand for miniaturized force sensors,a thin plate cantilever force sensor with low shape and small range is designed through the finite element method of Creo Simulate module.The force sensor has the advantages of simple structure,high strength and convenient application,and it also can meet the current demand for low shape and small range force sensors.Then the force sensor is made of alloy steel,and through the different combination modes of wheatstone bridge in the strain gauges,the influence of different bridge combination modes on the sensitivity output of the force sensor and the influence of eccentric load on the sensitivity output of different bridge combination modes are analyzed.
