        It analyzes the new structure and mechanism of organ type accel pedal to have a double curve to obtain a low effort force has been devised an electronic accel pedal consisting of two springs. To confirm the characteristics of effort force on variation of spring constants for two springs, dynamic analyzes were performed by using the ADAMS software program. According to the result of the simulation analysis, new mechanism of organ type accel pedal has an inflection point of the curve of pedal effort force on variation of spring constants, k, in various range of pedal angle.

        Spring constants (displacement per unit applied load) of MEMS socket pins of given structures were computed by theoretical analysis and confirmed by the finite element method (FEM). In the theoretical analysis, the displacement of pins was calculated based on the 2-dimensional bending theory of the curved beam. For the 3-dimensional modeling, CATIA was used. After modeling, the raw data were transferred to ANSYS, which was employed in the 3-dimensional analysis for the calculation of the stress and strain and loaddisplacement The theoretical analysis and the FEM results were found to agree, with each showing the spring constants as 63.4 N/m within a reasonable load range. These results show that spring constants can be easily obtained through theoretical calculation without resorting to experiments and FEM analysis for simple and symmetric structures. For the some change of shape and structural stiffness, this theoretical analysis can be applied to MEMS socket pins.
