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.

In this lecture, we reviewed the principle and types of force sensors with strain gages, tactile sensors based on MEMS and force sensor as well as nano force sensors. Also we investigated applications of force sensors for NT, BT and RT.

This paper presents the effective technique to design a six-axis load cell by using experimental design with an orthogonal array. A binocular structure is used as a basic sensing element for a load cell instead of the parallel plate structure. The finite element method is adopted to obtain strain distributions of the sensing element, and by doing the analysis of variances, its results are utilized in determining the factor which is more influential to the output strain. Calibration test results show that the developed six-axis loa cell with the maximum capacities of 196 N in forces and 19.6 N. m in moments is evaluated to be useful with the coupling error less than 2.5%.

This paper describes the build-up force measuring system of 9.9 MN capacity which consists of nine force transducers of each having 1.1 MN capacity. We have specially designed a force transducer for a build-up force measuring system to reduce the uncertainty of a build-up system and to accomodate the new test procedure for a build-up system. It reveals that the relative uncertainty of the force measuring system is less than 1.5*10$^{-4}$ in the ran9e of 1-4.5 MN irrespective of loading direction. The force measuring system may be used to calibrate a 10 MN force standard machine to be used as a large force standard in Korea.
