RT Journal Article SR Electronic A1 Gmiterko, Alexander A1 Virgala, Ivan A1 Vacková, Martina T1 Dynamic Analysis of the Two-Mass System to Imitate Rectilinear Motion of a Snake JF Acta Mechanica Slovaca YR 2010 VO 14 IS 4 SP 74 OP 81 DO 10.2478/v10147-011-0037-5 UL https://www.actamechanica.sk/artkey/ams-201004-0009.php AB A few previous decades the researchers and the designers started to copy the animal motion to the mechanisms. The principal motivations of the snaky locomotion are the environments where the traditional machines are not applicable due their dimensions or shapes and where the accessories like the wheels or the legs fail. The paper deals with the dynamic analysis of the two-mass system imitating the snake rectilinear motion on the level surface. Within the research there were made various modifications of the system and through the simulation was verified the behavior of the kinematic parameters. Based on the mentioned displacements and the speeds depending on the time it is possible to determine the optimal parameters of examined dynamic system.
