Abstract

The invention relates to a piezoelectric six-dimensional force sensor based on a Stewart structure design. The piezoelectric six-dimensional force sensor comprises an upper platform, a lower platform, six upper rod ball hinges, six upper connecting rods, six groups of piezoelectric one-dimensional sensors, six lower connecting rods and six lower rod ball hinges, wherein the upper platform and the lower platform are connected together through sensor branches formed by the connecting rods, the upper and lower ball hinges and the piezoelectric one-dimensional sensors; the six piezoelectric one-dimensional quartz crystal groups are respectively fixed in a groove formed between the upper connecting rods and the lower connecting rods through six uniformly-arranged bolts; each quartz crystal group consists of four xy type piezoelectric quartz wafers; the quartz crystal groups are bonded together by the quartz crystal wafers and electrode sheets through conductive adhesives. As a Stewart parallel structure and a partial load principle are utilized, the measurement of large range load is realized; as each crystal group consists of the four xy type piezoelectric quartz wafers, the piezoelectric six-dimensional force sensor has the characteristics of being high in measuring sensitivity, high in measuring result accuracy, simple in structure, convenient to mount and use and good in stability and can be applied to the measurement of strong load.
