Popis: This paper presents some results on the parameter estimation of a fixed-distance joint. Such joints are of interest in various fields of applied mechanics such as mechanisms, vehicle and human body dynamics. The corresponding geometrical parameters are positions of the points of connected bodies, which are kept at constant distance during the movement. The problem is solved using kinematical information on a certain number of points belonging to the connected bodies. The conditioning problem, and, consequently, the accuracy of the results, depends on the relative movement of the bodies and also on possible a priori information. The case of planar motion is investigated in more detail; a numerical example is provided and discussed.
