Abstract:

Is stated the research of kinematic and dynamic precision of planar RRRRT type five-bar hinged mechanism with two degrees of freedom with one clearance in the connection of two couplers that are applied in the special engineering for improvement of precision of reproduction of required geometry of surface of antenna mirror. The obtained results contribute to elimination of error and improvement of precision of reproduction of given law of motion.

Keywords: Five-bar mechanism; two degrees of freedom; kinematic precision; dynamic precision
