摘要
扭杆弹簧倾斜仪是一种结构简单的小型化倾斜仪,在工农业生产、地球物理和科学实验等方面有着广泛的应用。描述了扭杆弹簧倾斜仪的机械结构及工作原理,构建了扭杆弹簧倾斜仪原型,测定了扭杆弹簧倾斜仪的灵敏度和机械振子的本征频率,并对其温度特性和长期工作性能进行了实验研究。实验结果表明扭杆弹簧倾斜仪能实现对地面倾斜的精密测量。
Torsion pole spring tihmeter, whose structure is simple and small, is widely applied to production of industry and agriculture, physical geography and scientific experiment. The mechanical configuration and work principle of torsion pole tiltmeter are introduced and its prototype has been built. The sensitivity of device and the natural frequency of mechanical oscillator are measured. Moreover, experimental study on its important performances such as temperature characteristic and long-term working capacity has been carried through. The experimental results show the device can realize the precise measurement of the floor tilt.
