Scott russell mechanism3/10/2024 ![]() It is concluded that the numerically identified parameters of the complete model are almost the same as those of the real system, and the RGA method is feasible for the identification of the SR mechanism driven by the PA. From the comparisons between numerically identified dynamic responses and experimental results, it is found that the error percentages are within −1.4% ∼ 1.7% for the system without offset and −3.85% ∼ 3.33% for the system with offset. A Scott Russell linkage is a linkage which translates linear motion through a right angle. Theory of Machine A fixed gear having 200 teeth is in mesh with another gear having 50 teeth. The Scott Russell mechanism device of claim 9, wherein a rotation unit having a rotor is coupled to the joint unit, and a pivoting unit having. In system identification, the real-coded genetic algorithm (RGA) is adopted to find the parameters of the SR mechanism and the PA. In this paper, the main objective is to propose a complete mathematical model, including the driving circuit, Bouc–Wen hysteresis and mechanical equation, to describe the system. Russell mechanism device that allows a main arm member and a sub arm member to pivot at a base end part of both of the arm members to reduce a drive torque for turning both of the arm members, and to increase in degree of freedom in postures of various kinds of units attached to a tip end of the main arm member compared to the conventional degree. The main feature of the SR mechanism is its straight-line output for a given input displacement. The micro-positioning Scott–Russell (SR) mechanism driven by a piezoelectric actuator (PA) is designed to magnify the displacement of the PA.
