Precision and stability analysis of Maxwell-type kinematic mounts
Kinematic mounts (KMs) are often used in high- precision applications since they are self- locating and free from backlash, allow sub- micrometric re-positioning in static and dynamic applications, can accommodate differential thermal expansions, are not sensitive to contamination, are characterized by limited costs and their behaviour can be represented in closed form. Their main drawback is constituted by the high contact stresses that are to be analysed via the non-linear Hertz theory. The most common KM design configuration is designated as the Maxwell-type KM and is constituted by 3 V-grooves on one end (typically the support) and 3 spherical tops (typically balls) on the other end of the mount (typically supported piece) so as to achieve an exact constraint of all 6 spatial degrees of freedom (DOFs). The aim of this work is to analyse the influence of mechanical parameters on KMs’ behaviour and especially on their positioning precision and stability. An example of a KM used to support a large structure is considered.
