Specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and be embodied as
Example is described in detail to this utility model.
Shown in seeing figures.1.and.2, this utility model provides a kind of torsional oscillation test of double mass flywheel formula torsional vibration damper
Device, including the first frock 2, speed probe and processor.First frock 2 is used for replacing double mass flywheel formula torsional vibration damper
Secondary flywheel, the rotary inertia of the first frock 2 is equal to the rotary inertia of secondary flywheel；First frock 2 is cut with scissors with primary flywheel 1
Connect.Speed probe gathers the rotating speed of primary flywheel 1 and the first frock 2 during the work of double mass flywheel formula torsional vibration damper.Process
Device is for the vibration damping effect of the rotating speed analysis double mass flywheel formula torsional vibration damper of the rotating speed according to primary flywheel 1 and the first frock 2
Really.
Specifically, the primary flywheel 1 of the double mass flywheel formula torsional vibration damper of car load keeps constant.Secondary flywheel is replaced
It is changed to the first frock 2, the rotary inertia of the first frock 2 is consistent with secondary flywheel, so the double mass flywheel formula in car load is reversed
Rotary inertia during vibroshock work keeps constant.The rotating speed of the primary flywheel according to measurement and described first frock is analyzed double
The effectiveness in vibration suppression of mass flywheel formula torsional vibration damper.This device directly tests primary flywheel and the rotating speed of the first frock, directly perceived point
The effectiveness in vibration suppression of analysis double mass flywheel formula torsional vibration damper；Do not change the rotary inertia of double mass flywheel formula torsional vibration damper, can
With the accurate torsional oscillation effect testing double mass flywheel formula torsional vibration damper.
Furthermore, it is understood that the first frock 2 includes：Flywheel frock 5, is connected with primary flywheel 1 by bearing；Gear ring frock 4,
It is fixed on the outer rim of flywheel frock 5, the outer rim setting one of gear ring frock 4 is enclosed the tooth that tests the speed, thus can be surveyed by the tooth that tests the speed
The rotating speed of fixed first frock.After primary flywheel 1 and the first frock 2 assemble, primary flywheel 1 and engine crankshaft export hold-carrying
Blue disk is connected, and the flywheel frock 5 of the first frock 2 is arranged on primary flywheel 1 by a bearing (generally deep groove ball bearing)
On, the first frock 2 is provided with bell housing etc..Can relatively rotate between primary flywheel 1 and the first frock 2, primary winged
The vibroshock of wheel 1 and the first frock 2 installation typically selects spring as flexible member.So it is achieved that the first frock 2 generation
Secondary flywheel for the double mass flywheel formula torsional vibration damper of car load.
By in modeling software to double mass flywheel formula torsional vibration damper polarity model, calculate original model quality and
Rotary inertia.Determine that size, thickness and number of teeth of gear ring frock 4 etc. are joined according to rotary inertia equivalent transforming principle in modeling
Number, then calculate gear ring frock 4 and flywheel frock 5 combination after the first frock 2 rotary inertia it is ensured that the first frock 2 turn
Dynamic inertia is identical with the rotary inertia of secondary flywheel.
In addition, speed probe includes：First magnetic power rotation speed sensor, along being radially arranged of primary flywheel 1, be aligned is primary
The startup gear ring 3 of flywheel 1；Second magnetic power rotation speed sensor, along being radially arranged of the first frock 2, is directed at gear ring frock 4.Because
Under whole vehicle state, need using magnetoelectric transducer test double mass flywheel formula torsional vibration damper primary flywheel 1 and secondary flywheel
Rotating speed analyzing its effectiveness in vibration suppression.For primary flywheel 1, the startup gear ring 3 that carried due to itself, can directly adopt
The tach signal of the primary flywheel 1 as double mass flywheel formula torsional vibration damper for the rotating speed of collection startup gear ring 3.But secondary flywheel
There is no gear ring.For this, gear ring frock 4 is set in the outer rim of the first frock 2, and to keep the rotary inertia of the first frock 2 with time
Level flywheel is consistent.So the secondary flywheel as double mass flywheel formula torsional vibration damper for the rotating speed of gear ring frock 4 just can be gathered
Tach signal.
After having made the first frock 2, the secondary flywheel of double mass flywheel formula torsional vibration damper on car load is changed, install
First frock 2, magnetoelectric transducer is installed in the tooth punching near primary flywheel 1 and the first frock 2 simultaneously.
Shown in seeing figures.1.and.2, the startup gear ring 3 of primary flywheel 1 is provided with multiple teeth that test the speed, the first magnetoelectricity rotating speed
The corresponding gear ring 3 that starts of sensor 7 is arranged.Gear ring frock 4 is same with the set-up mode of the second magnetic power rotation speed sensor.Gear ring
The material of frock 4 and primary flywheel 1 is the soft magnetic materials of magnetic conduction, the such as metal such as steel, ferrum, nickel or alloy.The survey of torsional vibration signals
Amount analysis precision is closely related with tachometric survey precision.Magnetic power rotation speed sensor is needs and the tooth that tests the speed uses cooperatively, gear ring work
Fill 4 and start gear ring 3 tooth top smaller with the distance of magnetic power rotation speed sensor, generally carry out according to the installation requirement of sensor
Setting, about 1mm.Gear ring frock 4 and the number of teeth starting gear ring 3 are definite value.So, when gear ring frock 4 and startup gear ring 3 are synchronous
When rotation, tooth top and tooth root can cause magnetic gap to change uniformly through the surface of magnetic power rotation speed sensor.In probe coil
Middle generation induction electromotive force, in certain range of speeds, its amplitude is directly proportional to rotating speed, and the voltage of rotating speed more height output is more
Height, output frequency is directly proportional to rotating speed.
With reference to shown in Fig. 3, for a kind of torsional oscillation test device of double mass flywheel formula torsional vibration damper, can adopt as follows
Method of testing.Including：Described primary flywheel and described first frock during collection double mass flywheel formula torsional vibration damper work
Rotating speed；Wherein, the rotary inertia of described first frock is equal to the rotary inertia of described secondary flywheel, described first frock and primary
Flywheel is hinged；According to the described primary rotating speed of flywheel and the rotating speed of described first frock, analysis obtains double mass flywheel formula and reverses
