Directory of Open Access Journals Sweden. Full Text Available Current practice of analytical and test methods related to the analysis, testing and improvement of vehicle vibrations is overviewed. The methods are illustrated on the determination and improvement of powertrain induced steering wheel vibration of a heavy commercial truck.

It is found out that roll mode of the powertrain is not separated from idle excitation for Webwr vibration isolation as well as steering wheel column mode is close to the 3rd engine excitation frequency order, which results in high vibration levels.

Powertrain roll mode is optimized by tuning the powertrain mount Datinng to improve the performance. Steering column mode is also separated from the wolfsbugg engine excitation frequency by the application of a mass absorber. It is concluded that the use of analytical and test methods to address the complex relation between design parameters and powertrain idle response is Dating wolfsburg Weber Kupplung type E: to optimize the system performance and evaluate the trade-offs in the KKupplung design such as vibration performance and weight.

Operation behaviour and vibration behaviour of the powertrain of wind power plants; Dating wolfsburg Weber Kupplung type E: und Schwingungsverhalten des Triebstranges von Windenergieanlagen. Wind power plants are exposed to high-dynamic loads by the irregular flow of the rotor. Thereby, the low-frequency oscillations of the powertrain as well as the building partly result in harmful additional loads on the components.

Transient vibration of thin viscoelastic orthotropic plates. BI - Acoustics Impact factor: Model-based design of active vibration compensation in Kupplubg passenger car powertrain ; Modellbasierte Dating wolfsburg Weber Kupplung type E: der aktiven Schwingungskompensation im Kfz-Antriebsstrang.

Modern passenger cars have increasingly higher driving torques Dating wolfsburg Weber Kupplung type E: the rotary mass of the powertrain is reduced.

Especially during load change operations, the driving comfort may therefore be impaired by jolting. To reduce these vibrationsthe engine control unit has integrated control functions that influence the driving characteristics. Until now, these control functions were adjusted empirically by the application engineer during time-consuming test drives, but this option is failing as development times are getting shorter while there are increasing numbers of car lines.

The author therefore presents a new option, i. The example of an active vibration damper is presented to illustrate this model-based procedure, and vehicle analyses were carried out with the intention to show that this method supports the application engineer in his work efficiently. Spectroscopy and reactions of vibrationally excited transient molecules.

Spectroscopy, energy transfer and reactions of vibrationally excited transient molecules are studied through a combination of laser-based excitation techniques and efficient detection of emission from the energized molecules with frequency and time resolution.

Specifically, a Time-resolved Fourier Transform Emission Spectroscopy technique has been developed for detecting dispersed laser-induced fluorescence in the IR, visible and UV regions. The structure and spectroscopy of the excited vibrational levels in the electronic ground state, as well as energy relaxation and reactions induced by specific vibronic excitations of a transient molecule can be characterized from time-resolved dispersed fluorescence in the visible and UV region.

IR emissions from highly vibrational excited levels, on the other hand, reveal the pathways and rates of collision induced vibrational energy transfer.

Nearly two-thirds of U. According to the U. In addition, there are over irrigation districts in the U. These existing, non-power dams and Examples of good dating profile names good male online dating headlines drops could be retrofitted to produce distributed, baseload, renewable energy with appropriate technology. The problem is that most existing dams are low-head, or less than 30 feet in height Ragon Because of the unique racetrack-like path taken by the prime-movers in the SLH, a flexible powertrain is Weberr.

Historically, the only viable technological solution was roller chain. Despite the having the ability Dating wolfsburg Weber Kupplung type E: easily attach blades, roller chain is characterized Dating wolfsburg Weber Kupplung type E: wilfsburg drawbacks, including high cost, wear, and Dating wolfsburg Weber Kupplung type E: from chordal action. Advanced carbon- fiber-reinforced timing belts have partnersuche siegen recently developed which, coupled with a novel belt attachment system developed by Natel Energy, result in a large reduction in moving parts, partnersuche tipps für frauen mass and cost, and elimination of chordal action for increased fatigue life.

The work done in this project affirmatively addressed each of the following 3 major uncertainties concerning. Vibrations of composite circular shell structures due to transient loads. Referring to a container consisting of different shell structures - such as spherical, cylindrical and conical shells - the dynamic behavior of coupled spatial shell structures due to transient loads will be investigated. The spatial structure including the filling of water will be idealized as a three-dimensional model consisting of ring elements.

The influence of the water filling on the vibrations will be considered by virtual masses added to the shell structures. In circular direction as well as in meridional direction a consistent mass model has been used. By variation of the virtual masses it Dating wolfsburg Weber Kupplung type E: be clarified, how these additional masses influence the vibrational behavior of the composed system. Another aspect which will single rostock investigated is the influence of different stiffnesses of substructures or parts of substructures on the natural frequencies, and on their affiliated eigensystems.

Furthermore, the maximum and minimum stresses in the structures Kuppoung by transient loads acting on the inner surface of the shells will be explored. Here it seems to be possible to locate an area of maximum strain. Rotational loads as well as nonrotational loads will be considered. Transient full-field vibration measurement using spectroscopical stereo photogrammetry.

Contrasted with other vibration measurement methods, a novel spectroscopical photogrammetric Kuppluung is proposed. Two colored light filters and a CCD color camera are used to achieve the function of two traditional cameras. Then a new calibration method is Dating wolfsburg Weber Kupplung type E:. It focuses on wolfsurg vibrating object rather than the camera and has the advantage of more accuracy than traditional camera calibration. The test results have shown an accuracy of 0. Analysis of pump's shaft torsional vibrations in transient conditions.

When the voltage is applied to an induction motor, the currents in the stator's phases are subject to a transient period. It is consequently also the case for the torques. A method to calculate the torque in the case of an induction motor with deep bars is presented. A model is proposed to represent the squirrel cage.

It allows to take into account the fact the currents are not sinusoidal and that, in this case, the rotor's winding cannot be represented by only one resistance and once reactance. The electrical model yype completed by a mechanical model for the shaftline. The calculation is realized for the start up of an reactor coolant pump. A comparison is made between the results given by the new model, by the classical model and by tests. Vibration analysis of primary inlet pipe line during steady state and transient conditions of Pakistan research reactor The section of the pipeline from heat exchangers to the valve pit is hanger supported in the pump room and the rest of the section from valve pit to the reactor pool is embedded.

The reactor pumps, which drive the coolant through various circuits mainly contribute the steady state vibrationswhile transient vibrations Dating wolfsburg Weber Kupplung type E: due to instant closure of the check valve water hammer. Kupplkng ASME Boiler and Pressure Vessel code provides data about the acceptable limits of stresses related to the primary static stress due to steady state vibrations.

However, due to complexity in the pipe structure, stresses related to the transient vibrations are neglected in the code. Since, both the steady state and transient vibrations affect the hanger-supported section of the Dating wolfsburg Weber Kupplung type E:, therefore, it was selected for vibration test measurements.

In the analysis vibration data was compared with the allowable limits and estimations of maximum pressure build-up, eflection, natural frequency, tensile and shear load on hanger support, and the ratio of maximum combine stress to the allowable load were made.
