Stress strain analysis of membrane coupling
Sýkora, Tomáš ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This master’s thesis deals with the strain stress analysis of a membrane coupling with different membrane shapes and under different operating conditions. Thanks to their flexible membrane, these couplings are able to transmit torque even in the moment of misalignment of the connected shafts. However, too much misalignment is one of their most common causes of failure. For this reason, it is necessary to define the critical areas of the coupling during the design and to reduce these areas with the right optimization. For this purpose, a geometric and subsequently a numerical model of the membrane coupling for simulations using FEM software Ansys Workbench is created. At the beginning, the initial shape of the membrane is determined and according to the results of individual simulations, the shape is gradually optimized. At the end of the thesis, based on the distribution of equivalent stress in the membrane, the results of individual optimizations are compared and evaluated.

Application of Modern Technologies for a Design of Disc Coupling Production
Varhaníková, Alžbeta ; Varhaník, Matúš (referee) ; Sedlák, Josef (advisor)
The bachelor thesis deals with the design of disc coupling and its production by using 3D printing technology. Model of disc coupling and this thesis are supposed to serve as teaching equipment for students at Secondary vocational schools. The theory section contains the essay of shaft couplings with a detailed description of disc coupling, characteristic of individual methods of Rapid Prototyping technology and materials suitable for 3D printing. The experimental section is dedicated to the calculation and construction design of disc coupling and its production using the Fused Deposition Modeling method. The thesis also contains a description of post-production processing and assembly. The attachments of the thesis consist of assembly mechanical drawing and production mechanical drawing of drive disc.
