Research and applications of forward kinematics of six-bar parallel mechanism in synchrotron radiation beam-line[J]. Optics and precision engineering, 2008, 16(10): 1874-1879.DOI:
Six-bar parallel mechanism is widely used in synchrotron radiation beam-line now. But its six-dimensional adjustment is difficult and inefficient because of lacking theoretical direction. Based on the inverse kinematics
forward kinematics of six-bar parallel mechanism is obtained by trust region method for nonlinear optimization. The corresponding program with MATLAB language is also given. The result shows that trust region method is an effective way to study forward kinematics
and the program is stable
reliable and fast. This method has small errors with linear precision of 10-12mm and rotational precision of 10-15deg. Using differential snail adjustment
monochromator box’s attitude can reach a linear resolution of 5μm and a rotational resolution of 3". It completely satisfies the practical requirements.
