| Abstract: | The aim of this paper is creation, investigation of mono frequency and poly frequency plane and spatial vibrations of two mass vibration systems with a suitable adjustment of the mechanical system. The physical object is a vibrating jaw crusher. The mechanical and mathematical modeling is created on the basis of a two mass dynamic model with six degrees of freedom in plane case—three for each mass and 12 degrees of freedom in spatial model—six for each mass. The influence of the elastic linkages between the two masses and also the energy mutual linkages between the coordinates of the two bodies are investigated. Natural frequencies and amplitudes of movement are obtained by means of computer experiment in plane and spatial aspect. The obtained results can be used for optimization of the constructive parameters of the vibrating jaw crusher and also for improving harmful resonance effects |
