The column-type sensing element in building and mechanical construction parts was designed as three forces and three moments sensor by attaching strain gages approximately. Compared to conventional multi-component sensor, the designed sensor has high stiffness and low cost. The radius of the column was designed analytically and compared with finite element analysis. The interference errors between components were minimized by using addition and subtraction procedure of signals. The fabricated sensor was tested by using a deadweight force standard machine and a six-component force calibration machine. The calibration results showed that the 6-component forces and moments sensor had interference error less than 7.3 % between $F_x$ and $M_x$ components, and 5.0 % in case of other components.

In this study, we determined boundary condition of sensing element by nonlinear analysis of finite element method for minization of end loading effect. In order to stabilize output voltage of load cell, boundary condition of contact were optimized. Then measured output voltage from experimental study confirmed the result of the finite element solution. This study is a good design of compact cylinderical load cell by analysis of finite element method.
