MODAL ANALYSIS OF A SOIL LOOSENING MACHINE BASIC STRUCTURE
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2018, Vol 0, Issue 8
Abstract
The paper presents the resistance structure modal analyses of a SCAR-ART soil loosening machine, namely, determining the main own structure frequencies, as well as applications of the obtained data. For calculation is used finite elements module analyse of SolidWorks software, modal analyse sub-module. The geometry of the structure is constructed in the same program, after which the meshing and the frequency analysis are made, using a structural model constructed with linear elastic materials type, considering that in normal operation no tensions are achieved outside the linear elasticity range. The results consist in a number of 30 own frequencies and vibration that are used (the first 2-3) to avoid resonant operating modes. Also in perspective these can be used to simulate the resonant working regimes and identify possible damages under these conditions.
