Description
Technical field
The invention belongs to engine test facility technical field, specifically a kind of examination convenient for automobile engine installing and dismounting
Test rack.
Background technique
In automobile engine development process, carrying out durability test to test engine is indispensable to start machine examination
Step is tested, according to national regulation, the product for completing Engine Durability test can just be sold.Engine Durability test flower
It is time-consuming longer, engine need to be carried out with the uninterrupted continuous running of revolving speed corresponding at maximum power point by regulation
Verifying, and when some enterprise procurement engine products, it often requires that more strictly, may require that longer experimental period, engine
Development & production unit generally requires to carry out the continual several months and even more tests for a long time.
When test-bed carry out Engine Durability test necessaries, present test-bed during the test,
It needs to customize special fixture according to engine model to be measured to be used to hang engine, the special fixture includes bracket, is customized
Special fixture be fixed on erecting bed after, by engine hanging test.Since different model engine sling point is different,
Therefore it needs to customize multiple special fixtures, needs to expend substantial contribution, and need whole and erecting bed point when special fixture replacement
From, it is cumbersome, expend a large amount of artificial and times.
Engine to be measured is dragged into capable test by the way that the motor of experimental bench is counter, when test, needs engine output shaft to be measured
It is connected with motor shaft by shaft coupling, existing shaft coupling can not all stretch, if engine output shaft side to be measured occurs
Failure needs integrally to remove shaft coupling, step is very complicated when needing to tear open lid maintenance.Moreover, most of experimental stands in order to
Guarantee that motor is connect accurately with engine, first connects to move special fixture after shaft coupling again and determine when usual and to be measured start seat in the plane
It sets, guarantees that engine output shaft and motor shaft are coaxial, this results in generally require when dismounting coupling unclamping special fixture,
Extremely it is unfavorable for the maintenance repair of engine to be measured.
During the test, the record of test data and processing are most important, present experiment method often manually into
Row test data record, testing equipment only real-time measurement and can show relevant experimental data, manually record at regular intervals
Experimental data under the primary time point, this Experiment Data Records mode the case where there are test data misregisters, because
During test, experimental data is the numerical value of a dynamic change, and the experiment of certain point is only recorded when manually being recorded
Data, there are deviations, and it sometimes appear that the case where testing crew fails to record test data, test data is reaction test result
Pith, test data misregister or it is imperfect can not all obtain correct conclusion (of pressure testing), when serious even may require that
Test is re-started, a large amount of manpower and material resources and time are wasted.
