The aim of this thesis is the innovation of the testing device which is located in Institute of Machine and Industrial Design laboratory. The innovation relates to the portal construction design, where will be placed the hydraulic pulsator from the company INOVA Praha Ltd. New portal construction will be designed with respect to specified parameters and requirements and also with regard to the performed tests (damper tests, vibroizolated properties magnetorheological valves tests etc.). The thesis contains detailed analysis of the current tester and detailed analysis of similar machines with focusing on the portal structure and ways of positioning the crossmember. Further parts of the thesis is a detailed description of the design solution, including the computational simulations, attached drawing documentation and experimentally verified functional sample (crossmember).

This master’s thesis deals with the design of equipment for testing differentials. The aim of the thesis is therefore the design of a special device that will be able to measure the steady and transient characteristics of differentials. Master’s thesis is divided into four chapters. The first chapter points out the disadvantages of fully open and closed differentials, the second deals with a basic overview of the structures and design of self-locking differentials. The third chapter deals with research of existing devices that test and measure the characteristics of differentials. The fourth chapter then discusses the possible drives of the tested unit. The fifth chapter focuses on the actual construction design of the test equipment. The subsequent sixth chapter then solves the strength calculations of the chosen structural elements of this device.
