The elastomer of a parallel girder load sensor affects the measuring precision directly. According to the structure and feature of the elastomer of a parallel girder load sensor
the rational finite element model of the elastomer was built
and in the course of exploiting Auto CAD of the sensor
a method of the automatic generation of the finite element mesh was founded. Dealing with three instances of line intersecting
the relationship between the out-stain and the dimension of the structure was also founded. Finally
by means of ViziCAD
the stress and strain of the finite element were analyzed.Compared the calculated value with the measured one of the output sensitivity
it is proved that they are nearly identical.Therefore
the finite element method can improve the precision and efficiency of the manufacture.
