Description
Technical field
The utility model is related to urban rail wheel technical fields, specially urban rail wheel particle damping unit.
Background technology
Urban rail is inter-city rail transit or the abbreviation of urban track traffic, special service in urban inner or adjacent cities it
Between rail vehicle transportation system, in daily life, more tendency refers to inter-city rail transit to one word of urban rail, and city rail is handed over
General rule uses subway or one word of rail traffic to be generally called mostly, and urban rail is along with China city and inter-city rail transit Large scale construction
The life term and railway term of development and appearance, and correspondingly have the addresses such as municipal rail train, urban rail station, in fact, urban rail
The concept of one word is relatively general and rich, refers to the various passenger transporting Rail Transit Systems within the scope of short-distance and medium-distance, and damping refers to appointing
What vibrational system in vibration, external influence or system inherently due to the spy that is gradually reduced of caused Oscillation Amplitude
The quantization signifying of property and this characteristic is in response to the meaning of time in electricity, and the physical significance of damping is the decaying of power,
Or the energy dissipation of object during exercise generally exactly prevents object from continuing to move, when object is shaken by outer force effect
When dynamic, a kind of counter-force for making external force decay, referred to as damping force (or damping force) are will produce, the ratio of it and active force is referred to as damping
Coefficient, the direction of usual damping force is always with the directional velocity of movement on the contrary, therefore, the damped coefficient of material is bigger, it is meant that
Its effectiveness in vibration suppression or damping are better, but are not that damping is the bigger the better, damping it is big to a certain extent when two objects it
Between become rigid connection, damping generally is used together with spring, damps excessive, will not have the effect of buffering.
Wheel-rail noise is one of the Main Noise Sources in rolling stock traveling, is caused to the normal life of people serious
It interferes, the dynamic excitation that wheel is born in wheel track vehicle operational process is complex, exists axially and radially so as to cause structure
Two kinds of vibration modes, and dampers numerous at present can only inhibit unidirectional vibration, but wheel noise is mainly by circumferential mould
State and radial mode shape collective effect and cause.
