Design of clamping fixture for ultrasonic welding of plastics
Vojteková, Lucia ; Kandus, Bohumil (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated design of clamping fixture for ultrasonic welding – horn. In pursuance of literary studies and calculations there was created approximate shape of clamping fixture, which was created in 3D programme and tested by finite element analysis. Using the linear static analysis there were found some modal shapes of the horn. The purpose of simulations is to find modal shapes of analysed structure, which can cause damage of the horn or equipment. Analysis shows the real shape of vibrations of the tool, which can be always in one axis. With the help of correction of dimensions and shape there was found required frequency in working range of ultrasonic equipment. Suitable shape of the horn was processed into drawings. The material, from which is horn made of, is a titanium alloy TiAlMo74.
