Abstract. Causes of dimensional instability of instrument components and materials are considered, physical mechanisms of the instability manifestation are described. A combined computational and experimental method is proposed for evaluation of dimensional instability of assembly units. Urgency of the method application to precision instrument design is noted.
Keywords:
geometrical instability, resistance to plastic microdeformations, microcreep.
