The presented master’s thesis is focused on the design of device for spring dismount from shock absorber and measuring of its spring characteristic. Then is the thesis focused on the design of device for measuring the spring characteristic of anti-roll and torsion bars. The introductory part of the thesis describes the basic distribution of springs and their properties and also design variants of wheel suspensions. Next part introduces devices already available on the market. The following sections aim to the design of stated devices itself, i.e. the description of their parts and functions, the definition of output parameters and stress-strain analysis. Both designs, including the analyses and technical drawings, were created in Autodesk I...
