摘要
对Stewart六维力传感器进行了优化设计分析,在有限元分析的基础上,通过球头球窝结构、十字槽结构以及圆环内嵌十字梁结构等形式,增强了传感器整体的抗耦能力。同时,对优化前后的传感器进行了试验比对,在一维加载时,传感器的最大误差由3.28%减小到0.41%;在三维加载时,最大误差由4.76%减小到2.22%。从以上的数据可以看出:改进后的设计更加合理,提高了传感器的精度。
Optimization design and analysis on Stewart six-dimensional force sensor is carried out,on the basis of finite element analysis,through ball head ball socket structure,cross recessed,and ring embedded cross beam structure.anticoupling ability of sensor is strengthened.At the same time,experimental comparison is carried out on optimized and non-optimized sensor.The sensor maximum error is reduced from 3.28 % to 0.41 % with one dimensional load,the maximum error is reduced from 4.76 % to 2.22 % with three-dimensional load.It is shown from above datas that the improved design is more reasonable and the precision of sensor is increased.
