Keywords:automated assembly, vibration, alignment, passive compliance
AbstractThe paper aims to simulate the process of the compliantly supported peg alignment with respect to the bushing, which is provided with vibrations in the axial direction and to analyse the influence of the parameters of the dynamic system and excitation on the alignment process. Considering the lateral and angular compliance of the supported device the mathematical model of the parts interaction during the alignment process is formed and numerical simulation is performed. The dependencies of the alignment duration upon the pressing force of the parts, the lateral and angular stiffness of the elastic constraints, the amplitude and frequency of the excitation, the coefficient of sliding friction and geometrical parameters of the compliant device are determined. The alignment can be performed only when the parameters of the mechanical systems and excitation are adjusted. The alignment of the peg occurs during the motion from the static to the dynamic position of equilibrium of the mechanical system. The distance between these positions determines the maximum axial misalignment of the parts under which the alignment is still possible.
