The torsional vibration tester solves the installation problem of a contact sensor in a torsional test, and provides higher precision for acquisition and analysis of torsional vibration test signals.
Description
Technical field
The utility model relates to the torsional test field of automobile engine crankshaft twist vibration damper, particularly relates to a kind of new type crank torsional vibration damper torsional test device.
Background technology
When carrying out the torsional test of automobile engine crankshaft twist vibration damper, for the angular encoder of contact, how scrambler being installed on the engine crankshaft front end is a common problem that exists.After general engine crankshaft is used for the built-up crankshaft vibration damper, the exposed portions serve of crankshaft front end is shorter, be not enough to the angle of assembling scrambler, the diameter of the engine crankshaft of each vehicle also has nothing in common with each other in addition, and the through-hole diameter size of angular encoder is a standard fixed, angular encoder directly can't be installed on the engine crankshaft front end, must design a coupling arrangement, with angular encoder and engine crankshaft connection, be convenient to gather the torsional vibration signals of engine crankshaft front end.
Modal engine crankshaft front end torsional signals is picked up mode for there being two kinds: 1) use the non-contact laser sensor, stick equidistant lattice cursor paper at the crankshaft front end end face, measure high-precision rotational speed pulse signal, thereby carry out Analysis of Torsional Vibration.Its advantage is to realize non-contact testing, but sensor is expensive, and measuring accuracy is subjected to the factor sensitivities such as stickup right alignment, light power environment and measuring distance of cursor paper.2) use the contact angular encoder, it is coaxially installed on the engine crankshaft front end, measure high-precision rotational speed pulse signal and carry out Analysis of Torsional Vibration.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new type crank torsional vibration damper torsional test device, solving the installation question of touch sensor in the twisting test, and provides higher precision with analyzing for the collection of torsional test signal.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of new type crank torsional vibration damper torsional test device is provided, comprise angular encoder, connecting link, base, crankshaft tortional vibration damper and engine crankshaft, described base is fixed in the middle of the described crankshaft tortional vibration damper, and by the base set bolt described crankshaft tortional vibration damper is connected with described engine crankshaft; Described connecting link is fixed on the described base; The through hole of described angular encoder passes described connecting link, and is fixed on the described connecting link.
The connecting link of described new type crank torsional vibration damper torsional test device is fixed on the described base by the connecting link set bolt.
The through hole of the angular encoder of described new type crank torsional vibration damper torsional test device is that minim gap cooperates with the fit system between the described connecting link, and installs and lock onto on the described connecting link by the scrambler locking device.
The connecting link and the base of described new type crank torsional vibration damper torsional test device are made by No. 45 steel.
The scrambler locking device of described new type crank torsional vibration damper torsional test device is made by aluminium alloy.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect: 1) need not expensive non-contact laser sensor; 2) this test frock is easy to processing, and fabrication cycle is short; 3) be easy to guarantee the right alignment of sensor and engine crankshaft, improve measuring accuracy; When 4) test figure is gathered, the not strong and weak influence of tested person ambient light, quick and easy for installation, safe and reliable.
Description of drawings
Fig. 1 is a sectional structure synoptic diagram of the present utility model;
Fig. 2 is the crankshaft torsional vibrations angular displacement result who adopts the utility model to record.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present utility model relates to a kind of new type crank torsional vibration damper torsional test device, as shown in Figure 1, comprise angular encoder 2, connecting link 3, base 6, crankshaft tortional vibration damper 7 and engine crankshaft 8, described base 6 is fixed in the middle of the described crankshaft tortional vibration damper 7, and by four base set bolts 5 described crankshaft tortional vibration damper 7 is connected with described engine crankshaft 8; Described connecting link 3 is fixed on the described base 6 by four connecting-rod bolts 4; The through hole of described angular encoder 2 passes described connecting link 3, and both fit systems are that minim gap cooperates, and install and lock onto on the described connecting link 3 by scrambler locking device 1.Described connecting link 3 and base 6 are made by No. 45 steel; Described scrambler locking device 1 is made by aluminium alloy.
The vibration damper torsional test device of certain in-line four cylinder engine under the stand installment state, under the full load operating mode, engine speed accelerates to the 6000rpm scope from 1500rpm is even, and its torsional oscillation Measurement results curve is seen shown in Figure 2.Torsional oscillation angular displacement Order combination value comprises more than 1.5 rank, and 0.5 rank, every interval are by the total value (1.5+2.0+2.5 to 12 rank ... + 12).0.5 rank are considered to noise signal usually to 1 rank, influence the total value evaluation, therefore in total value these orders are filtered.Mate this torsional vibration damper, have maximum single-order time torsional oscillation angular displacement 0.136deg at 4510rpm, the contribution order is 6 rank.Judge as can be known that by actual test result use the utility model vibration damper torsional test device to carry out the crankshaft tortional vibration damper torsional test, data result is true, credible, accurate.The test unit processing and fabricating cycle is short, and is easy installation and reliable, is a relatively crankshaft tortional vibration damper torsional test device of novel practical.
Be not difficult to find that the utility model need not expensive non-contact laser sensor, the test frock is easy to processing, and fabrication cycle is short, is easy to guarantee the right alignment of sensor and engine crankshaft, improves measuring accuracy.When test figure is gathered, the not strong and weak influence of tested person ambient light, quick and easy for installation, safe and reliable.
