摘　　要：针对三维加速度测量的特点 ,研制了一种新型应变式全剪切三维加速度传感器。该传感器为电阻应变式 ,采用了薄壁圆筒上开双层错位孔形式的弹性元件 ,从而实现了三维加速度量都利用剪切应变测量。有限元分析计算和初步的实验结果表明 :所研制的加速度传感器 3个正交方向上都有较高的灵敏度和足够的刚度 。A new type of three-axis acceleration sensor has been developed, which can be used to measure three axis accelerations sensitively and truly. The sensor is a type of strain gauge. Its yielding part is a thin cylinder on which four holes are opened evenly at each of the two levels. On the same level, so the arrangement allows convenient gaining of shear stress in each of the axes. As indicated by the calculations and experiments, this sensor is not only of high sensitivity and adequate rigidity in all the three axes, but also of fairly small cross sensitivities and low hysteresis.
