Abstract
The invention discloses a combined vibration-damping device for a diesel power generating set of an internal combustion locomotive, which comprises a diesel engine arranged on a bottom plate of a locomotive body; and rubber vibration dampers are symmetrically arranged on the two sides of the diesel engine. The combined vibration-damping device is characterized in that the inclined hydraulic vibration dampers are symmetrically arranged on the two sides of the diesel engine. The combined vibration-damping device has the benefits that the vibration of the power generating set is buffered by utilizing the rubber elasticity of the rubber vibration dampers, and meanwhile, the vibration energy of the power generating set is adsorbed by utilizing the inclined hydraulic vibration dampers; each inclined hydraulic vibration damper has the vibration-damping resistance characteristic, so that the vertical and transverse high-frequency and low-frequency vibration of the power generating set can be reduced, and the vibration of the locomotive is further reduced; the partial position or the fitting resonance phenomenon is eliminated, the premature fatigue of structural strength of a synchronous power generator, the diesel engine, the locomotive body and other mechanical parts is retarded, and the service life is prolonged; and the comfort of trainmen is improved.
Description
Technical field
The present invention relates to a kind of vibration damping equipment, particularly relate to a kind of combined damping device of diesel locomotive diesel generator set.
Background technique
At present, internal combustion locomotive newly make, overhaul and in repair diesel generating set test after, diesel generating set is used four bearings with rubber shock absorber to be installed in to carry out vibration damping on the locomotive car body, its vibration damping mode only adopts rubber shock absorber, effectiveness in vibration suppression is undesirable.
Internal combustion locomotive has two large vibration sources on the locomotive when operation, namely diesel engine itself is a uneven mechanism of motion, produces easily vibration; Main generator rotates, and also can produce vibration.Because Vibration of Diesel Generator Set, may form resonance at local location or accessory and cause high vibration.Locomotive adopts integral body, and crackle, welding are bad if the vehicle frame part has, distortion etc., cause vehicle frame rigidity inadequate, and the diesel generating set basis is insecure, larger vibration also occurs easily.Now only cushion the vibration of diesel generating set with rubber shock absorber, locomotive occurs causing whole locomotive vibration because of Vibration of Diesel Generator Set when actual motion easily.
Therefore, do not reach in the situation of desirable effectiveness in vibration suppression at single employing rubber shock absorber, those skilled in the art demands designing more preferably vibration damping equipment of a kind of effectiveness in vibration suppression urgently.
Summary of the invention
Purpose of the present invention just provides a kind of diesel locomotive diesel generator set combined damping device, adopts the mode of rubber shock absorber and tilting dydraulic shock absorber combination to carry out vibration damping, and effectiveness in vibration suppression is better, can overcome above-mentioned the deficiencies in the prior art part fully.
Purpose of the present invention realizes by following technical proposals:
A kind of diesel locomotive diesel generator set combined damping device comprises the diesel engine that is arranged on the hull bottom plate, and the diesel engine bilateral symmetry is provided with rubber shock absorber, it is characterized in that: also be symmetrically arranged with the tilting dydraulic shock absorber in the diesel engine both sides.
Further, described diesel engine sidewall is provided with fitting seat, and correspondence is provided with lower fitting seat on the hull bottom plate, and tilting dydraulic shock absorber two ends are inclined between diesel engine sidewall and the hull bottom plate by upper and lower fitting seat.
Further, the oil hydraulic cylinder external diameter of described tilting dydraulic shock absorber is φ 50mm～φ 300mm.
Further, described tilting dydraulic shock absorber has more than 2 pairs, span 50mm～1000mm between adjacent two pairs of tilting dydraulic shock absorbers.
During the work of tilting dydraulic shock absorber, piston is to-and-fro motion in oil cylinder, produce the vibration damping resistance through orifice valve when fluid flows in piston cylinder, the tilting dydraulic shock absorber absorbs the vibrational energy of generator set simultaneously, and the vibrational energy of generator set is converted into the heat energy of fluid and dissipation.
Beneficial effect of the present invention is: simple in structure, reasonable in design, utilize the vibration of the rubber elasticity buffer dynamo group of rubber shock absorber, and utilize simultaneously the tilting dydraulic shock absorber to absorb the vibrational energy of generator set.The tilting dydraulic shock absorber has the vibration damping drag characteristic, can reduce the vertical and horizontal high and low frequency vibration of generator set, and then reduction locomotive vibration, eliminate local location or accessory resonance phenomenon, slow down the structural strength premature fatigue of the mechanical parts such as synchronous main alternator, diesel engine and car body, and increase the service life, improve crew's travelling comfort.
