Abstract
A method for testing durability of starter includes loading maximum drag torque required to be overcome to start up starter on brake at engine test table, carrying out load of drag torque on brake dynamically according to variation curve in course of starter being started up and tracking speed variation of engine flywheel after dead start up time, controlling rise-up of overriding motor rotary speed to be synchronized with flywheel, switching off power supply of starter when clutch is on and speed rise-up of motor is controlled to be power switching-off rotary speed.
Description
[technical field]
The present invention relates to a kind of auto electric detection method.
[background technology]
At present, following scheme is taked in the endurancing of starter substantially: the one, starter is installed on the engine that matches, and to test and count with manual method, the performance that this method efficient is low, can not accurately reflect starter adopts less; The 2nd, starter is installed on the simulated engine stand, carry out simulation test, this method efficient height, more accurate, starter factory adopts the method more.As shown in Figure 1, be the structural representation of simulated engine starter durability test board, system comprises starter 1, engine flywheel 2, dynamic torque sensor 3, magnetic powder brake 4, electromagnetic clutch 5, variable-frequency motor 6, connects successively.By magnetic powder brake 4 loading simulation engine loadings, surmount rotating speed by variable-frequency motor 6 simulated engines.When on the simulated engine stand, starter being done endurancing at present, be to adjust load by the load parameter of stipulating in the starter product technology condition, starter starts, after dead 1 second start-up time, electromagnetic clutch adhesive work is risen by the Frequency Converter Control motor speed, starter switch disconnects during to the outage rotating speed, the speed of variable-frequency motor continues to rise to the rotating speed that surmounts of setting, and frequency converter is output as zero, the clutch coupling outage.Start once more through starter after set cycle length, successively circulation.This analogy method can not truly reflect the overall process that engine is started: 1, adjust load by the load parameter of stipulating in the starter product technology condition, can not truly reflect engine by in the starting process because the descending change procedure of the moment of resistance of the moment of inertia engine of flywheel; 2, starter startup, after dead 1 second start-up time, engine flywheel had a certain speed and continued rising this moment; Electromagnetic clutch adhesive work just continues to rise with same speed chased after the speed that is raised to flywheel by the Frequency Converter Control motor speed after.This does not conform to the practical working situation of engine yet.
[summary of the invention]
Purpose of the present invention is exactly in order to overcome the above problems, and a kind of not only convenient, but also endurance performance testing method for starter more accurately is provided.
For achieving the above object, the present invention proposes a kind of endurance performance testing method for starter, comprise the steps: 1) on simulated engine starter durability test board, load engine and be activated the maximum resistance square that need overcome and give detent, start starter, 2) be activated moment of resistance change curve in the process carries out the moment of resistance to detent dynamic load according to engine, 3) after dead start-up time, the engine flywheel rotation speed change is followed the tracks of immediately, control surmounts motor speed and rises, 4) when motor speed and flywheel synchronous, clutch coupling work, when system's control motor speed rises to the outage rotating speed, power-off of starter.
Above-mentioned endurance performance testing method for starter, the described moment of resistance change curve process of obtaining: on block testing stand, measure engine and be activated the curve that the moment of resistance changes in the process, copy in the control system of simulated engine starter durability test board.
Above-mentioned endurance performance testing method for starter, also comprise the steps: power-off of starter after, motor speed continues to rise to the rotating speed that surmounts of setting, frequency converter is output as zero after start-up time, the clutch coupling outage.Behind the described engine kill, after 22 seconds rest, system enters test loop next time.Be 1 second described dead start-up time.Be that starter starts the time to engine kill described start-up time, is preferably 8 seconds.Described outage rotating speed is made as 1000r/min.The described rotating speed that surmounts is made as 2500r/min.
Owing to adopted above scheme, controlled simulation loading according to engine by load change curves in the starting process, to dead start-up time intrinsic motivation flywheel rotation speed change follow the tracks of immediately, control and surmount the motor speed rising, existing simulated engine testing table simulation loading lotus and the inaccurate shortcoming of simulated engine rotating speed have been improved, more real simulation the engine situation of being started, the test operating mode that makes tested starter is more near real working condition, each measured parameter of starter is more accurate.
Parameters such as preferred test rotating speed, time can guarantee the operating mode that simulated engine is more realistically started, and can guarantee the efficient of testing again.
[description of drawings]
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Fig. 1 is a simulated engine starter durability test board,
Fig. 2 is used for petrolic starter test period synoptic diagram.
[embodiment]
At first on the Engine Block Test platform, measure the curve that engine is activated the descending variation of the moment of resistance in the process, copy to then in the control system of simulated engine starter durability test board as shown in Figure 1.In starter durability can be tested, detent is carried out the dynamic load of the moment of resistance according to this curve.
In conjunction with Fig. 1, shown in Figure 2, carrying out starter durability can test the time, the computer control system of simulated engine starter durability test board at first provides an engine and is activated the maximum resistance square that need overcome and gives magnetic powder brake 4, Closing Switch, and actuating motor 1 starts.Be activated the curve that the moment of resistance changes in the process according to above-mentioned measured engine under the entrucking state, computer control system is sent a dynamic moment and is given magnetic powder brake 4, warp dead start-up time of t
1=1s, simultaneously control system is followed the tracks of immediately to flywheel 2 rotating speeds, surmounts rotating speed and flywheel 2 synchronization of motor 6 by Frequency Converter Control, and electromagnetic clutch 5 is worked afterwards, is risen by Frequency Converter Control variable-frequency motor 6 speed.Engine speed reaches the power-off of starter rotation speed n
2Starter 1 outage during=1000r/min, the speed of variable-frequency motor 6 continues to rise to the rotation speed n that surmounts of setting
3=2500r/min is through t start-up time
2Frequency converter is output as zero behind the=8s, clutch coupling 5 outages.Experience set engine time of having a rest t
3Starter 1 starts once more behind the=22s, successively circulation.
