Tractor Shift Mechanism Analysis
Netopil, Jan ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The thesis focuses on the shifting mechanisms of manually shifted tractor transmissions. It provides a comprehensive overview of all significant structural nodes of the shift mechanism with an analysis of the influence of the structure on the resulting intensity of a force required for shifting. The main aim of this thesis is the design and validation of experimental equipment for measuring the force effects of the shift mechanism of a mass-produced tractor in actual operation. The design of the experimental equipment is based on a study of the used measuring technique and similar experimental equipment. The final structure is selected based on selection by the method of weighted values, taking into consideration the requirements of the structure. A functional measuring chain is designed and formed for the realization of the measurement. To evaluate the data from the technical experiment, a multibody model of the designed experimental device is created in the MSC Adams View software, through which the real parameters of the shift mechanism are obtained from the measured values. The designed experimental equipment brings the possibility of complete analysis and subsequent optimization of the tractor's shift mechanism

Scooter testing bench
Kostka, Marek ; Dlugoš, Jozef (referee) ; Zháňal, Lubor (advisor)
This Master’s thesis deals with measuring of acting forces from rider to footbike during the ride, followed by the construction of test stand to draw an equivalent load. Measurements and subsequent analysis of acting forces from the rider to the footbike were made. These results were then used for complete design of the test stand. The frame of the test stand was subdued to a stress analysis. A complete automatic control system, including a pneumatic control circuit, was also designed. The proposed automatic test stand was then manufactured and put into operation.

Test Rig Design for Durability Testing of the Rubber Segments
Borek, Vojtěch ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The aim of diploma thesis is construction design of test rig for durability testing of the rubber segments. The work contains a brief description of tested component, test rigs and individual parts of the testing system. Next chapter describes conception and construction solutions with justification of choice specific parts, supported by analysis of critical parts. Finally the overall construction design is evaluated and accompanied with a documentation of drawings, which is attached to the thesis.

Rig for Testing Suspension Components
Nedoma, David ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
Development of car suspensions needs optimalisation of comfort, durability over external conditions, reduction of un-sprung mass, car handling. This requirements often need contradictory solutions and during solving it is necessary to take compromises. Verification of durability of car suspension is better while developing the whole car. Therefore, many solutions of car suspension test rigs are created. This thesis brings summary of existing solutions and their construction. This thesis brings its own solution of the suspended test equipment, strength calculations of main components. You can find here procedure of testing components on this test rig as well. Written ideas for future development of this rig are mentioned in last chapter

Driveline Design and Testing Methods
Poláček, Jan ; Straka, Tomáš (referee) ; Fojtášek, Jan (advisor)
This bachelor’s thesis deals with the methods of designing and testing of vehicle drivetrains. The first part of the thesis describes and explains the individual drivetrain components and their possible arrangements. Then, the test methods used in the development of vehicle drivetrains, which are increasingly demanded in terms of their efficiency and reliability, are explained. Therefore, this thesis summarizes the sophisticated simulation tools used in the design and development of vehicle drivetrains. In conclusion of thesis the importance of simulation and testing of drivetrain is considered.
