Sažetak
The work adresses the parasitic motion of a high-precision rotation mechanism based on cross-spring pivots. From the analytical point of view, the problem is approached by studying the large deflections of an elastic frame. The equilibrium equations are considered, and a solution based on the Newton-Raphson method is proposed. This approach is compared with other theoretical approaches. An experimental assessment performed by using laser interferometric techniques is presented. It is shown that the proposed solution permits to establish clearly the influence of lateral loads and provides an adequate approach when the most common cases of limited lateral loads and rotations are considered.
