Dynamic Error Analysis

This lecture covers the analysis of dynamic errors in precision mechanisms, focusing on the relationship between theoretical and real movements, sources of error, and the impact of natural frequencies on movement amplification. It also delves into the modeling of dynamic systems with flexible elements, harmonic responses, and the effects of parametric vibrations. The instructor presents examples of harmonic excitation, positioning errors, and the calculation of dynamic amplification coefficients. Additionally, the lecture explores the response of uniform mechanisms to periodic movements, the decomposition of command signals into harmonic series, and the calculation of total responses. Emphasis is placed on the distortion introduced by the amplification factor and the occurrence of resonances in systems with infinite harmonics.
