“…One way to reduce the weight is to use lightweight construction materials of high strength. These requirements are met by composite materials based on metal and polymer alloys, which are increasingly used in mechanical engineering and transport [42,43,44,45,46,47,48,49,50,51].…”

This paper presents the results of laboratory tests in which evaluation was performed regarding the effect of selected operating factors on the vibroactivity of upper gearbox housings made of three different fiber reinforced polymer composite materials with diverse layouts (cross and random) and types of reinforcing fibers: glass fiber and carbon fiber. The results of tests for composite housings were compared with those for a steel housing. The tests showed that composite housings had a weight lower by more than 60% compared to the steel housing. A multisensor measuring system consisting of vibration acceleration transducers, a directional microphone and a data acquisition card with software was used for the study. Tests of the vibroactivity of upper gear housings were carried out at different loads and rotational speeds of toothed gears. The study showed that composite housings are less sensitive to changes in the rotational speed that steel housings. The tests showed that at a higher rotational speed of the gear transmission, housings made of composite materials had a comparable or lower level of vibration. Tests and analyses of the vibroactivity of housings performed at different loads of the gear allow the conclusion that composite housings, despite a considerably lower weight than steel housings, are less sensitive to changes in the load of the gearing.

The current trend of weight reduction entails a reduction in safety factors. This approach is understandable, but light profiles are more susceptible. The structure works close to the boundary loads, and their destruction is primarily determined by dynamic relief. Today, composite masts are diagnosed by the following methods: optical microscopy, electron microscopy, X-ray analysis and thermal analysis. These methods are invasive methods. It seems that the vibration analysis of the mast-rigging system could supplement or replace the mentioned methods without the need to dismantle the mast, giving the possibility of testing on the yacht [5]. The article presents the possibility of diagnosing a composite material defect on the example of a interrupts a continuity of structure.

“…The calculation accuracy can be improved, when the sophisticated construction requires, by a precise composition of torsional moments (with taking into account their variability) instead of a composition of amplitudes only [13], followed by the more detailed dynamic analysis. The fatigue strength problem becomes then of an essential meaning [14]. Algorithms beginning the train of calculations from satisfying dynamic assumptions in the range of critical states did not catch on, so far [13,15].…”

The main goal of this paper is, that if we want to correctly identify dynamic model of drive shaft made of carbon-epoxy composite, we must take into account the influence of deformation velocity on elasticity characteristic. In the paper, Authors showed the effect of passing shaft resonance (1st critical speed). It was shown in the conditions of acceleration and braking with different increases of rotational speed. When examining the results obtained with empirical and model research, it has been shown that in the structural design of carbon fiber drive shafts, the main factor affecting the right development of the structure should be dynamic criterion, since the only use of static criteria leads to big errors.
