The formation of errors caused by temperature processes in mechanisms built on the principles of parallel kinematics

Abstract

Abstract The article discusses issues related to the process of formation of the total error affecting the position error of the output link of mechanisms with a parallel structure caused by thermal deformations of the leading links. Movable rod mechanisms allow you to create lightweight technological machines for complex technological operations: finishing turbine blades, the production of art products, complex configurations, as well as medical devices and navigation equipment. The causes causing a change in the temperature state of the mechanisms under consideration are considered. A technique for determining the position of the output coordinate as a result of deviation from a given trajectory is presented.
