This paper presents the results of vibration characteristic of tamping device. Firstly, the basic working principle of tamping device was simply described; Then a simulation model of tamping device was established using SIMULINK in terms of mechanism principle; Finally, some vibration parameters were researched, such as velocity, acceleration, displacement of tamping device, which reflect the vibration characteristic of tamping device. In addition, the modeling process of simulation model was described, the function of SIMULINK was also simply recommended. The main aim of this paper is to propose an analysis method on facility vibration characteristic, which visualized reflects the kinematics characteristic of mechanism.

The rail transport (railway lines, shallow subway lines or passing on the surface) is a source of increased vibration.As a result, predicting the parameters of vibration and the structure-borne noise generated by it when designing residential and public buildings near lines or designing new transport lines is an important task. For operating lines, the initial data for the forecast are the results of measurements of vibration parameters at the location of the projected building. For projected lines, the parameters characterizing the source of vibration - the vibration characteristics of moving trains - should be used as the initial data for the forecast. The method for railway trains vibration characteristics determination is described which based on field measurements. As an example of the method application determination of vibration characteristicsof suburban electric trains running along the line of the Savelovsky direction of the Moscow railway is sited. Linear regressions equations are given that connect the weighted vibration velocities in the horizontal direction of vibration propagation perpendicular to the railway line with the train speed

Modeling Process

This chapter reports on the use of simulation in supporting decision-making about what data to collect in a randomized clinical trial (RCT). We show how simulation also allows the identification of critical variables in the RCT by measuring their effects on the simulation model’s “behavior.” Healthcare systems pose many of the challenges, including difficulty in understanding the system being studied, uncertainty over which data to collect, and problems of communication between problem owners. In this chapter we show how simulation also allows the identification of critical variables in the RCT by measuring their effects on the simulation model’s “behavior.” The experience of developing the simulation model leads us to suggest simple but extremely valuable lessons. The first relates to the inclusion of stakeholders in the modeling process and the accessibility of the resulting models. The ownership and confidence felt by stakeholders in our case is, we feel, extremely important and may provide an example to others developing models.

The paper aims at issuing of a virtual simulation model that would be able to assess the actual working modes of a torque converter, both hydraulically and mechanically. To estimating the dynamic behavior we used the assessing equations of the converter’s performance coefficients. The rotational inertial phenomena due to the transient regimes during the getaway phase are also considered. The modeling process assumed the use of the pre-defined structures of the Simulink-Matlab and Simscape-Matlab modules. The virtual model of the torque converter was fed with the experimentally determined, performance parameters as input. The input also consisted of the inertia moments of the converter’s components. Eventually, by interrogating the simulation model, we’ve got and plotted the time histories of the converter’s impeller and turbine angular velocities during the vehicle’s getaway process.

ABSTRACT: The objective of this research was to use the modeling and computer simulation to support decision makers, aiming to increase the productive capacity of the agro-industry of LaticínioFunarbe. Specifically, it has modeled the current yoghurt production sector for simulation that enables it to meet the new demand. The Arena 14.7 simulation software was used to conduct the modeling. To validate the model, the output of yoghurt production collected at the factory for three months was compared with the output from the simulated computational model. Two indicators were established to perform analyzes of four different scenarios. The implemented model resulted in an increase in the production capacity of 5,000L.d-1 of yoghurt, corresponding to a production of yoghurts processed daily three times higher than the current production.

Product design and simulation have been long used to support their enterprise-wide engineering activities. This paper describes, in detail, a case study and solution of a simulation process management project called performance simulation model (PSM) .We focus on several research issues, including integration of design process and simulation process, simulation data management, simulation flow management, and the architecture of PSM.
