“…According to many works, e.g. [19,22,23], for a correct assessment of dynamic phenomena in toothed gears, it should be used dynamic models with an extended description of the meshing properties, damping, stiffness, the torsional and flexural rigidity of shafts. Models should allow simulations with variable speed and load conditions.…”

The article presents the concept and up to now developed stages of the simulation program for the analysis of dynamic phenomena occurring during the operation of power transmission systems of various means of transport. Currently completed stages of work allow simulation of drive systems with cylindrical gear or planetary gear. The starting points for the implementation of the assumed goal were earlier developed by author considering two independent dynamic models of drive systems with a simple single-stage cylindrical gear and with a planetary gear. Naval and vessel power transmission systems are one example of the fields of application of the developed program. The spread of mechanical propulsion in shipping, which occurred in the nineteenth century, led to different research problems. These include, above all, fuel consumption, which resulted, among others from the efficiency of the entire system. The need to ensure proper performance, avoid unplanned voyage breaks or meet environmental requirements, imposed by increasingly stringent emission standards, results in the search for effective power transmission system solutions and optimization methods for existing ones. One of such methods is dynamic modeling of drive systems, and an example tool that enables the use of this method is the simulation program presented in the article. During development of the concept of the simulation program we admitted the assumption that the model shall enable the determination of dynamic phenomena that occurs in various construction designs of power transmission systems in both-constant and variable conditions of their operation. Thanks to this, the simulation program can be used in two directions of research. The first direction of research is the optimization of newly designed and existing drive systems, and especially the optimization of the construction of toothed gears. It is possible, among others by taking into account the actual, not only assumed, nominal operating conditions. Besides, the dynamic model used by the simulation program allows a wide range of modifications to numerous design features of the system, including the geometry of toothed gear elements. The second direction of research is the development of efficient methods for detecting local damages of system components. Simulation of various combinations of defects in the power transmission system, including damages of gears and bearings, allows also for more effective improvement of present diagnostic algorithms of toothed gears working in power transmission systems of various transport means.

The purpose of this research was to analyze the possibilities for the application of vibration signals in real-time train and track control. Proper experiments must be performed for the validation of the methods. Research on vibration in the context of transport must entail many of the different nonlinear dynamic forces that may occur while driving. Therefore, the paper addresses two research cases. The developed application contains the identification of movement and dynamics and the evaluation of the technical state of the rail track. The statistics and resultant vector methods are presented. The paper presents other useful metrics to describe the dynamical properties of the driving train. The angle of the resultant horizontal and vertical accelerations is defined for the evaluation of the current position of cabin. It is calculated as an inverse tangent function of current longitudinal and transverse, longitudinal and vertical, transverse, and vertical accelerations. Additionally, the resultant vectors of accelerations are calculated.

The paper presents results of research on hydraulic automotive shock absorbers. The considerations provided in the paper indicate certain flaws and simplifications resulting from the fact that damping characteristics are assumed as the function of input velocity only, which is the case of simulation studies. An important aspect taken into account when determining parameters of damping performed by car shock absorbers at a testing station is the permissible range of characteristics of a shock absorber of the same type. The aim of this study was to determine the damping characteristics entailing the stroke value. The stroke and rotary velocities were selected in a manner enabling that, for different combinations, the same maximum linear velocity can be obtained. Thus the influence of excitation parameters, such as the stroke value, on force versus displacement and force versus velocity diagrams was determined. The 3D characteristics presented as the damping surface in the stoke and the linear velocity function were determined. An analysis of the results addressed in the paper highlights the impact of such factors on the profile of closed loop graphs of damping forces and point-type damping characteristics.
