Design of a stubble cultivators for aggregation with a tractor 75k
Krutský, Lukáš ; Fajkus, Pavel (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor's thesis deals with the design of a fully mounted cultivator in a three-point tractor hitch, cat. 2N/2. A short search of similar equipment and tractors of the corresponding power range was performed. The concept is designed and based on analytical calculations of dimensional and functional properties. Strength calculations are performed according to the standard, critical points of the equipment are checked. The work contains pictures of 3D models and drawing documentation.

Two-axle tractor semitrailer
Krafka, Martin ; Fajkus, Pavel (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deals with the design of a specialized trailer with a tandem axle for transporting commodity raw materials and materials. The introductory section of the thesis deals with defining legislative requirements and classifying the trailer into vehicle categories. The following section is dedicated to the methods of constructing individual parts of the trailer. A market survey of trailers with a tandem axle and similar nominal load capacity to the proposed trailer is conducted. The design section focuses on the trailer design with a choice of purchased trailer components. A finite element analysis of stress states is created from a shell model with replacements of structural nodes to approximate the real state of loading. The thesis also includes drawing documentation.

Concept of the rotary harrow
Moštěk, Michal ; Fajkus, Pavel (referee) ; Kašpárek, Jaroslav (advisor)
The bachelor's thesis deals with the design of a rotary harrow. In the beginning of the thesis, a short research is written regarding soil cultivation. Rotary harrows and tractors in the corresponding power series are listed in the next chapter. In the next part of the work, individual components are described and their selection is justified. The construction of individual components is described in a separate chapter. The rotary gate is designed with a three-point hinge cat. 2N/2. In the last part of the work, the strength calculation of the gears, the basic durability of the rotor bearings and the inspection of the shaft of the bearings is carried out. Calculations are made according to standards. The work includes drawing documentation and images of the 3D model.
