An Analysis of Mechanism Kinematics Accuracy Based on Linear Elastic
The simulation-based prediction of the mechanism kinematics accuracy is of great importance in engineering application. For widely used and low-cost open-loop mechanism having no feedback signals, it is important to take a balance between economic consideration and high accuracy requirement, thus containing high research value. Based on current widely used methods, this paper proposes a more precise method to revise the kinematics accuracy of movement mechanism. Considering the manufacture error and joint clearance in mechanism, we reckon in elastic deformation displacement caused by gravity load and inertia force, that the analytic expression of displacement correction is presented, and that it is independent of the Business Software. Theoretical analysis and case studies show that this amendment for the precision request is necessary.
