Development of a magnetorheological shock attenuation system for military applications
Vývoj magnetoreologického systému tlumení rázových dějů pro armádní aplikace
Aim of thesis: In military applications, effective shock attenuation is an important requirement. This may include damping of gun recoil, damping of seats in the event of a vehicle explosion or fall, and more. Current scientific contributions reveals that the combination of a magnetorheological (MR) suspension system together with semi-active control can be a significant advance in this area. Typically, piston velocities are in the units of m/s and high damping forces are achieved. These are therefore quite extreme operating conditions for dampers. The main focus of this work will be study of the behaviour of MR fluid at high velocities and the subsequent application of this knowledge to the design of a magnetorheological damper. The design of sensors and damper control will be important as well. The main focus of the work will be the development and experimental verification of MR suspension systems operating at high piston velocities.

Research on noise generation and propagation in rail transport
Výzkum vzniku a šíření hluku v kolejové dopravě
Aim of thesis: Noise generated by the operation of rolling stock is an ongoing social problem. One of the main sources of strong noise is wheel-rail contact. In the case of abnormal operating conditions, excessive lateral vibration of the wheel can occur, leading to the emission of a strong acoustic signal. Although some hypothetical mechanisms of wheel-rail contact noise behaviour have been described, a number of phenomena have still not been satisfactorily investigated. Especially in the context of the modern approach of adhesion management on risky track sections through the application of liquid or solid substances to the surface or sides of the rail. The aim of this thesis is to investigate the influence of operating conditions in modified contact on the occurrence of unwanted noise and its propagation to the surroundings.

Advanced bearing diagnostics for wind farms
Pokročilá diagnostika ložisek pro větrné elektrárny
Aim of thesis: Wind power (WPP) is one of the world's most widespread alternative sources of electricity. The desire to maximize the efficiency of the plant leads to high demands on the mechaniocal design and high reliability of all structural components. Critical components include the driveline bearings. Due to the time-varying loads, it is difficult to reliably determine their service life. At the same time their failure during operation must be prevented, as the entire turbine can be heavily damaged and high reapair cost will be required. The aim of this work is to develop an advanced predictive diagnostic method for monitoring the technical condition of the wind turbine bearings using non-destructive testing methods.

Advanced downhill bike suspension
Pokročilé odpružení sjezdového kola
Aim of thesis: The goal of the thesis will be to develop an intelligent suspension system for electric mountain bikes. Current commercially available electrically controlled wheel suspension systems do not utilize the potential of rapid semi-active control. Current systems only enable automatic valve control, which has to be adjusted manually in older dampers and is not able to ensure better-driving characteristics. Fast semi-active damping with magnetorheological dampers enables a qualitative shift in achievable driving comfort and wheel grip on the road. Demonstrators of individual components are currently being developed. However, these components will have to be integrated into the entire functional system and experimentally verify the functionality. The work will focus mainly on identifying the limiting properties of real system elements (dampers, sensors, etc.) and the subsequent design of optimal system control.
Cooperation with a commercial partner in the field of mountain bike production and their suspension is assumed.

Development of diagnostic method for testing of the active suspension
Vývoj diagnostických metod pro testování aktivních odpružení
Aim of thesis: With the development of electric vehicles and the increasing comfort and safety requirements of passenger cars and motorcycles, actively controlled suspension systems are becoming used with increased trend. Such suspension can adapt its characteristics to the operating conditions. In the case of a semi-actively controlled suspension, the control algorithm can not only react to the immediate driving conditions but also compensate for minor or slowly developing wear on suspension components such as shock absorbers. At present, there is no reliable test method available to assess the correct function of actively controlled suspension. The aim of this work would be to develop a method that would allow correct function of the suspension to be diagnosed and possibly detect some common faults, e.g. increased shock absorber wear etc.

Development of the measuring system for monitoring and protection of plant grow
Vývoj měřicího systému pro monitoring a ochranu rostlin
Aim of thesis: The trend towards efficient use of natural resources affects a wide range of sectors, including agriculture. For proper plant growth, it is essential to choose the right irrigation method to avoid underwatering or overwatering the plant and possibly wasting water. To decide whether a plant needs watering, it is necessary to know its current condition. As previous research has shown, plant condition can be reliably monitored using the acoustic emission (AE) method, which has emerged as a sensitive method for diagnosing fatigue damage to bearings. Based on the data obtained from AE sensors, decisions can be made about watering and possibly the dosage of additional soil nutrients, etc. AI control can also be used to make decisions. Automated control can then be used for automated irrigation systems for greenhouses or for hydroponics, etc. The aim of the work is then to develop a suitable measurement method that allows reliable monitoring and to develop an algorithm for evaluating the data obtained.
