Computer Simulation of Wagon Body Bearing Structure Dynamics During Transportation by Train Ferry

The increased pace of Ukraine's integration into the system of International transport corridors necessitates the development of combined transport systems. Train ferry services are one of the most promising in this direction. To ensure the movement safety of wagons on train ferries, estimating the forces acting on them in a rough sea is needed.An analysis of the literature, describing the features of the sea transportation of wagons, led to the conclusion that the issue has been neglected to date. In this connection, a computer model of the strength of the fragment of the train ferry with the wagon bodies, placed on its decks, which takes into account the range of the main forces acting on the ship and wagons in a rough sea was developed.The computer simulation results allow to determine the magnitude of dynamic loads on the wagon body bearing structure during transportation by train ferry.The studies may be taken into account when designing new-generation wagons at wagon works that will increase the motion safety of wagons in the sea.

Development of A Mathematical Model to Monitoring the Velocity of Subsidence of Charge Material Column in the Blast Furnace Based on the Parameters of Gas Pressure in the Furnace Tract

A problem of estimating the velocity of subsidence of a column of charge materials using non-contact methods was considered. This is important because the level of furnace charge materials and the velocity of their subsidence are main indicators of melting intensity determining the furnace productivity. The design of a blast furnace and its blast path were described and existing methods and means of controlling the velocity of charge materials in the blast furnace were analyzed. A mathematical model was presented for estimating the velocity of subsidence of charge materials in a blast furnace based on the magnitude and fluctuations of gas pressure along the furnace shaft height. The model is based on the fact that the furnace gases rise up in the furnace shaft through elementary channels in the column of charge materials consisting of a combination of capacitances and resistances. Volume of capacities and values of resistance of elementary channels are constantly changing. This changes hydraulic resistance to gas movement in the blast furnace. The system of differential equations describes the dependence of the amplitude of pressure fluctuations on the amplitude of change in coefficients of resistance and frequency of pressure fluctuations on the frequency of change in coefficients of resistance. The experimental data on velocity of the column of charge materials and fluctuations in the pressure differential in the furnace were processed and their significant relationship was shown to confirm the previous theoretical study results. To assess the model adequacy, the simulation method was used. The results of the simulation model work were confirmed by experimental data. The developed mathematical model can be introduced into production. This will make it more economical and safer through better and more predictable control and improved flexibility in operation under different production conditions.

Different Pendulum Type Dynamic Vibration Absorber Aplication

The paper considers the methods of calculation and optimization of different pendulum type dynamic vibration absorbers for the vibration reduction of elongated elements. Discrete-continuous models of the dynamics of oversize elongated elements based on the Timoshenko beam theory with attached discrete elements are presented. Algorithms for the vibration reduction of elongated machine elements are obtained.Noise and vibration are associated with many mechanical systems including industrial, household appliances, transportation machinery and buildings. Many of these structures are made up of beam type elements. Once the system parameters are defined, beam system vibration can be reduced using passive damping.The dynamic vibration absorber is effective, reliable and inexpensive device to reduce vibration, caused by harmonic or narrow-frequency disturbance. In the classical theory of dynamic vibration absorber, the primary structure is modeled by a mass-spring system, though other models also find interesting theoretical and engineering applications. In particular, pendulum type systems with a solid body at a fixed rotation point play an important role as a model in many branches of mechanical engineering, transport and construction. The application effect of the pendulum type dynamic vibration absorber with shock masses may significantly differ from using the mass-on-a spring system.Research and optimization of different type dynamic vibration absorbers are performed. Timoshenko beam with different clamping conditions and different type dynamic vibration absorbers are used as a model for many real systems, described in the literature. Methods of decomposition and numerical synthesis are considered based on the adaptive schemes. Structures of elongated elements of machines and buildings with regard to their interaction with the system of dynamic vibration absorbers are examined. The optimization method of dynamic vibration absorbers to reduce excessive vibration of the Timoshenko beam system under harmonic and shock perturbations is developed.
