“…The torque ripple can be a source of vibration and acoustic noise [19][20][21][22][23]. Vibration in railway vehicles makes passengers uncomfortable [24]. Therefore, for the traction motor, it is necessary to design the no-load back-EMF and torque ripple as small as possible so that passengers experience a comfortable ride [25].…”

“…First are the internal excitation of the gears, and next the external excitation due to the input torque. A model to study the effects of this kind of excitation on the housing of the high-speed trains is presented in [4] using a multibody dynamic model. This model takes into account the elastic deformation of the wheel set and the gearbox housing.…”

“…4. Measurement and experimental analysis of noise radiated by the surfaces of adder gearboxes (a) Noise radiated from the front surface of the summing boxes:• At a speed of 500 rpm, for the dominant resonant frequencies of 395, 660, and 1600 Hz (determined in chapter 5), the noise radiated by the new variant adder box decreased by 8% compared to the noise radiated by the old adder box.• At the speed of 1000 rot/min, for the dominant resonant frequencies of 395 and 660 Hz, the noise radiated by the new variant adder box decreased by 10% compared to the noise radiated by the old adder box.…”

In the manufacture of commercial trucks, used in oil installations or the army, two identical engines are used on a single chassis, whose power is summed by a gearbox, a compact metal construction, which must meet multiple operating requirements. The paper studies the behavior of such an adding box, currently used in manufacturing, and an improved, welded solution that produces less noise and has a lower weight. The finite element method is used for modeling the gearbox in order to analyze stresses and strains and obtain a modal analysis of the system. The results obtained from the calculation are then verified by experimental measurements. The two versions are analyzed in parallel to highlight the advantages of the second version.

“…The first type is due to the internal excitation of the gears and the second type is represented by the external one due to the motor torque. There are established models for the study of vibrations that occur in such systems [4] using multibody dynamic systems. In the mentioned work, the elastic deformation of the wheelset and the deformation of the gearbox housing are taken into account.…”

In this paper, a study of the vibrations that appear in the transmission shafts of an adder gearbox used for a heavy truck is made. The truck has two engines on only one chassis and the power offered by these engines is summated and transmitted to the truck or the working machine. This type of transmission is used for oil production installation for the army. During the transportation of the installation to the workplace, only one engine is running, after mounting installation, both engines are running. This paper studies the vibrations of the adder gearbox, a complex construction, subjected to multiple operating requirements. In this regard, the authors first performed accuracy (accuracy) tests of the VIC 3D system on an original experimental mini-stand. Measurements performed on a mini disc demonstrated the validity and accuracy of the method, even if the cameras used were not high resolution. The authors applied the same principle in the case of the adder box from the truck, obtaining useful results for those in the field. The experimental method uses the facilities of a contactless optical measurement method (VIC-3D), which provides a high-accuracy quantitative linear and angular vibration analysis. The VIC measurement method offers, based on a frontal viewing of the disk during the resonance phenomenon and by simple calculus on the monitored linear displacements, the corresponding angular amplitude.
