Herein for internal-combustion engine vibration damper for chip vibration damper introduces technological scheme and technique effect, and in order to make those skilled in the art understand technological scheme of the present invention better, below in conjunction with method, structure, the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 1 is the flow chart of the setting method of I. C. engine crankshaft vibration damper in a kind of specific embodiment of the present invention.
The invention provides a kind of setting method of I. C. engine crankshaft 1 vibration damper, the method is specially:
The MAP of S1, establishment engine swept volume and damper rings rotary inertia; The establishment of MAP can utilize existing gross data, and the acquisition workload of gross data is less, can certainly carry out the data that actual tests records, and test data measured is more accurate;
S2, according to described MAP, set the ring rotary inertia that damper rings rotary inertia corresponding to a certain engine swept volume is standard vibration damper 3;
And, search the ring rotary inertia of required vibration damper from MAP according to Current internal combustion engines discharge capacity, and then with the ring rotary inertia of the ring rotary inertia of current required vibration damper and standard vibration damper 3 between the two magnitude relationship for basis for estimation, choose a described standard vibration damper 3 or several described standard vibration damper 3 is combined to form damper assembly as current complete machine vibration damper.
This magnitude relationship can be ratio relation, also can be difference relationship, continues to introduce technological scheme herein for ratio.If the current required ring rotary inertia of vibration damper and the ring rotary inertia ratio of standard vibration damper 3 are less than or equal to 1 (or 1.2, ratio coefficient can set arbitrarily), that is, if the ring rotary inertia of current required vibration damper is less than or equal to the ring rotary inertia of described standard vibration damper 3, then a described standard vibration damper 3 is set in bent axle 1 end; In like manner, if above-mentioned ratio can select the described standard vibration damper 3 of combination two for damper assembly is as current complete machine vibration damper between 1 to 2.
