| 摘 要： | 基于钢缆索索力传感理论模型和环式结构的索力传感器,对索力测量原理做了详细推导,传感器输出感应电压与激励磁场变化、加载外力变化、某一激励磁场下的材料磁导率及空气间隙尺寸等有关.重点分析了激励磁场变化对传感器输出的影响,分别在激励磁场为稳恒直流磁场、交流磁场、按矩形波规律变化磁场三种情况下对传感器输出进行了讨论和仿真分析.仿真结果表明,在稳恒磁场激励下,可通过感应积分电压求缓变外力,通过感应电压求得非缓变外力.在交流激励下.激励磁场频率对传感器输出有明显影响,频率越高,由激励磁场变化所引起的感应电压幅值越大.

| Abstract: | Based on the theoretical model of cable tension sensor and one loop-shaped stimulative structure of cable tension sensor,the basic principle of cable tension measurement is discussed.Sensor output may be determined by air clearance,magnetic permeability,magnetic field,stress and inductive loop denseness.The sensor output effects resulting from magnetic field are deeply analyzed when the magnetic field is constant,alternating and rectangular.In addition,sensor output effects from magnetic changing have been ... |
