A 3-DOF simulation turntable with perpendicular errors is introduced. The characteristics of period and variation in the perpendicular error are liable to bring about orientation error, which is a function of the overall static inaccuracy. Aimed to compensate orientation error, a perpendicular error calibration method is proposed to measure the perpendicular error between the axis and the bushing of a rotating axis in simulation turntable. Based on transformation matrix, gesture transformation matrix with various error items is achieved. As a result of this analysis, perpendicular error analysis is carried out when this measurement result is applied to a simulation turntable. Furthermore, this study also permits the user to know how to minimize some error sources of the simulation turntable.

Many errors including perpendicular error influence the accuracy of simulation turntable, which is a crucial equipment in hardware-in-the-loop simulation system. The aim of this paper is to propose a new method of perpendicular error motion separation of rotating spindle on a simulation turntable. Based on transformation matrix and small angle approximation, gesture transformation matrix with various error items is achieved. As a result of this analysis, perpendicular error analysis is carried out when this measurement result is applied to a simulation turntable. Furthermore, this study also permits the user to know how to minimize some error sources of the simulation turntable.

“…For the precise mechanical system, the contact state and the contact stress distribution of the assembly surface will greatly influence on the assembly accuracy. In the traditional minimum surface based on assembly process optimization model, statistical calculation is used, but it does not consider the particularity of each component error in precision mechanical system in small batch production [7][8][9][10][11][12][13][14][15] .…”

Abstract. The assembly accuracy of precision structures is significantly affected by the geometric error and thermal deformation of the mechanical components which can be represented by entropy. This paper provides an assembly process optimization method based on maximum entropy theory, optimizing multi-objective assembly process through the calculation of precision assembly system and entropy. This method can meet the requirements of high precision and high stability of precision mechanical system.
