The present invention relates to a kind of structural damping of vehicle body of the guideway vehicle that is used for modular construction.
Background technology
Vehicle body is the supporting construction of guideway vehicle.In usually known structure, vehicle body is by weld together integrally or differently soldered or point is welded into a steel frame from sheet steel from aluminium section bar.Vehicle body also can comprise the module that links together by welding, bonding, riveted joint or screw bonded assembly method.
The dynam of vehicle body is directly relevant with the travelling comfort of guideway vehicle.At the run duration of guideway vehicle, second is that spring suspension is sent to the motion of circulation bogie truck on the body structure.If a natural frequency in the natural frequency of stimulating frequency and structure is consistent, excited vibrational can transmit and increase on amplitude in the clear so, if especially body structure demonstrates a low relatively damping.Therefore, the minimum natural frequency of the oscillation frequency of bogie truck and body structure need be separated.
The needs of natural frequency usually cause the increase of tare.In the specific structural damping of a vehicle body, travelling comfort can improve by the additional measure of putting more energy into.When the cross section of vehicle body when being a certain amount of, this can utilize thicker structure member to obtain, and this structure member has increased the weight of vehicle body.This effect of long vehicle body for high-speed train has increased significantly, and each vehicle body in this high-speed train all bears the weight of extra 1-2 ton to realize the rigidity needs.This has increased for example feed stock cost conversely, to the requirement of wheel and axletree, and the abrasion factor of track and energy cost.
Except internal equipment and accessory, air flue and external device for example glued window accessory, car door and the bellows, be that damping by supporting construction produces to the main contribution that damping rose of vehicle now.In vehicle body, depend on the basic natural frequency and the structural damping of vehicle body according to the travelling comfort of transverse acceleration.According to summarizing qualitatively, the effect that increases structural damping on travelling comfort is big more, and the natural frequency of vehicle body is just low more.Physical cause is damping, as a kind of vibration control measure, only produces on the frequency that resonates effective at damping structure.Similarly, if the speed of guideway vehicle increases, perhaps vehicle operating is on narrow track, owing to there is higher excitation level in the frequency limit of elastic model, the effect of vehicle body damping is more obvious so.
Therefore, the increase of vehicle body damping allow to reduce the weight of vehicle body and/or provide less safe level between the oscillation frequency of bogie truck and minimum vehicle body natural frequency.
