摘要：The vibration of structure are cusecs generation heat on the machine parts, the heat generation dependent
onto the natural frequency supplied on the structure and the materials types (mechanical and thermal
properties). Therefore, in this paper investigation the heat generation in the beam due to vibration of beam
under frequency excitation (harmonic load excitation), for the beam supported with various boundary
conditions, simply supported; clamped supported; and cantilever supported beam. Also, the results
included evaluated the heat generation as a function of time with different frequency applied of harmonic
load, less and more than the natural frequency of beam. The heat generation due to vibration of beam with
time is evaluated by analytical investigation and comparison with numerical study, by using finite element
method with CFD package program. The results evaluated are shown the generation heat is decreasing
with increasing the frequency of the applied harmonic load. In addition to, the value of natural frequency
of beam, dependent is effect on the heat generation of vibration beam, therefore, the supported types of
beam are effect of the heat generation due to harmonic load, since the natural frequency of beam is
dependent on supported types of beam. The comparison of results between analytical investigation and
numerical work had shown the good agreement between with maximum error about (1.36%).
