Special Issue Information

Dear Colleagues,

Industrial machines for different materials processing constitute the basis of any technological chain. At the design stage, developers of machines optimize them for better performance, less energy consumption and required strength capacity along with endurance. However, during the operation, different factors such as excessive wear of parts or improper maintenance play a dominant role in the overall reliability of machines and affect the final product quality. The variable operating conditions cause non-stationary loading and different kinds of unpredicted dynamic effects in industrial machines like tumbling mills, drilling machines, steel rolling mills, underground longwall shearers, excavators, belt conveyors, vibrating screens, load-haul-dump vehicles, etc.

Online vibration monitoring systems can be efficiently used not only for failure prevention and remaining useful life prediction but also in machine dynamics control and process stability supervising. However, extended studies are required on modal analysis and internal structural resonances including the mutual influence of treated material and machine tools depending on specific features of technology. Dynamics of certain industrial machines may exhibit numerous nonlinear phenomena, which may occur due to clearances in the drivelines, gear meshing, synchronization of coupled drives, friction-induced oscillations and natural modes variation. Application of the appropriate analytical models and selection of signal processing methods has a significant effect on dynamics control, process stability, product quality and safe operation of machines. Even a small reduction in dynamics may have a great effect on the overall machine performance and reliability.

This is a call for papers for a Special Issue on "Dynamics Control and Vibration Monitoring in Industrial Machines". This Special Issue will provide a forum for researchers and practitioners to exchange their latest theoretical and engineering achievements in the analysis of dynamic phenomena of industrial machines. The general goal is to identify critical issues and challenges in the design and operation of machines having a complicated structure. Results of on-site experimental research are mostly encouraged for submission. The theoretical papers accepted into this Special Issue are expected to contain original ideas and potential solutions available for real problems resolving.

Topics include, but are not limited to, the following domains:

  • Model-based control of machines dynamics and process supervision;
  • Influence of treated material on machines dynamics;
  • Active vibration control and passive damping;
  • Case studies of different resonances in the machines;
  • Methods of signal processing and data mining for faults diagnostics;
  • Torsional vibrations in the drivelines of rotating machines;
  • Self-excited vibrations (friction-induced and regenerative chatter);
  • Shock and vibration in high-power hydraulic systems;
  • Modal analysis and design optimization of the multi-body systems;
  • Diagnostics of clearances in the bearings and powertrains couplings;
  • Instrumentation for condition monitoring in a harsh environment;
  • Strength capacity under stochastic loading with non-Gaussian distribution;
  • Cyclic fatigue calculation and remaining useful life prediction.

Theoretical investigations into the capabilities of a coaxial inertial drive with various operating modes for vibratory conveyors and screens are conducted in the paper. The coaxial inertial exciter is designed with one asynchronous electric motor and the kinematically synchronized rotation of two unbalanced masses. Three variants of angular speeds ratios, namely ω21 = 1, ω21 = –1, and ω21 = 2, are considered. Based on these relations, the circular, elliptical, and complex motion trajectories of the working members are implemented. In the first two cases, single-frequency harmonic oscillations take place. In the latter case, the double-frequency periodic oscillations are excited. The dynamic behavior of the motor’s shaft during its running-up and running-out is considered. The influence of the inertial parameters of the unbalanced rotors and the relative phase shift angle between them on the elliptical trajectories of the vibratory system’s mass center motion is investigated. The use of forced kinematic synchronization provides the motion stability of the vibratory system for all considered working regimes. Full article

The tooth root crack fault is a common fault type of the spiral bevel gear pair (SBGP). Affected by the strong bearing capacity, the early crack fault of the SBGP cannot be found in time. In this study, a finite element (FE) model of the SBGP is established and assembled through the tooth contact analysis. The maximum tooth root stress is analyzed considering the variation of assembly errors. Meanwhile, this study simulates the tooth root crack fault of the bevel pinion with different crack degrees. The initial position of the crack is located where the maximum tooth root stress appears. The time-varying mesh stiffness (TVMS) of the SBGP considering different degrees of the pinion tooth root crack fault is obtained. The TVMS and the non-load transmission error are brought into a hybrid FE dynamic model, and steady responses are solved. Based on this, the sensitivities of various statistical indicators for identifying the tooth root crack fault of SBGP under the influence of assembly errors are verified. This paper can provide the necessary theoretical basis for the analysis and diagnosis of tooth root crack faults in the SBGP transmission system. Full article
