Abstract
The utility model discloses a novel series-connected series-parallel combined intelligent dynamometer. The novel series-connected series-parallel combined intelligent dynamometer comprises a four-quadrant operated AC motor and a disc type current vortex dynamometer, wherein the four-quadrant operated AC motor and the disc type current vortex dynamometer are coaxially arranged to be an integral body via the same main shaft. The novel series-connected series-parallel combined intelligent dynamometer is of a reasonable structure, can satisfy the dynamic tests of European III-European V high-performance common rail engines, and can be intelligently switched to an engine stable state test with no disturbance. The dynamometer can satisfy the test precision of a low-power engine, and two dynamometers can be utilized simultaneously so that the test of a large-power engine is satisfied. Moreover, through the automatic test of feed electric energy by a system and through intelligent switching, the feed electric energy is automatically balanced with the power consumption of a lower enterprise electrical network when a plurality of dynamometers are working simultaneously.
Description
Technical field
The utility model relates to a kind of dynamometer.
Background technology
Along with developing rapidly of domestic automobile, engineering machinery in recent years, the research and development of engine, production capacity also significantly promote thereupon.Especially along with country improves the emission from vehicles standard; And force to carry out and implement; High performance high-pressure common rail EFI Europe III-Ou V low emission green environmental protection engine is day by day promoted and volume production, thereby forces the requirement to engine performance measuring equipment also to improve thereupon.
Present domestic engine performance measuring equipment all is to adopt energy consumption type water turbulence or current vortex measurement of power more than 95%, because of advantages such as its control stiffness is good, measuring accuracy is higher, use is reliable are used for the engine delivery test in a large number.But, its intrinsic dynamic response does dynamically test because of waiting shortcoming to satisfy not the above high-performance enginer of Europe III slowly.In recent years newly research and develop the engine " energy recovery type alternating current dynamometer " of production from external package import with my company; Have high dynamic response, engine cold state towing astern, measuring accuracy and advantages such as automaticity height, the recovery of engine output function feed, and promoted the use of by each engine research and development institution and manufacturing enterprise.But because feedback electric energy is limited by present domestic confession power distribution network in the Engine Block Test process; Can only be incorporated into the power networks with enterprise (or research and development institution) lower end internal electric network; So feedback electric energy is greater than the real-time electricity consumption situation of enterprise when often causing many alternating current dynamometers to work simultaneously; Cause feedback electric energy to flow backward to city's big net of supplying power, violate and supply the power distribution network relevant regulations through substation transformer.Therefore in enormous quantities use of alternating current dynamometer is restricted.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the novel serial connection series parallel type intelligence dynamometer of favorable working performance.
The technical solution of the utility model is:
A kind of novel serial connection series parallel type intelligence dynamometer is characterized in that: but comprise four quadrant running alternating current generator and disc type eddy current absorption dynamometer, but four quadrant running alternating current generator and disc type eddy current absorption dynamometer are mounted to an integral body through same main shaft is coaxial.
But on four quadrant running alternating current generator front end output shaft, adorn contactless phase differential high precision torque sensor.
But the four quadrant running alternating current generator is connected with the Direct Torque Control AC converter, and the disc type eddy current absorption dynamometer is connected with PID control DC excitation loading system.
The utility model is rational in infrastructure, can satisfy the dynamically test of rail engine do altogether of Europe III ~ Europe V high-performance, also can not have disturbance intelligence and switches to the engine steady state test; Can satisfy the low-powered engine measuring accuracy, also can two dynamometers use simultaneously and satisfy the high-power engine test; Automatically test the feed electric weight through system, and switch, feed electric energy and enterprise's lower end electrical network power consumption self-poise in the time of can also realizing automatically that many dynamometers are worked simultaneously through intelligence.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
A kind of novel serial connection series parallel type intelligence dynamometer, but comprise four quadrant running alternating current generator 1 and disc type eddy current absorption dynamometer, but 2 four quadrant running alternating current generators and disc type eddy current absorption dynamometer are mounted to an integral body through same main shaft 3 is coaxial.
But on four quadrant running alternating current generator front end output shaft, adorn contactless phase differential high precision torque sensor 4.But the four quadrant running alternating current generator is connected with the Direct Torque Control AC converter; Disc type eddy current absorption dynamometer and PID control DC excitation loading system is connected, and the two realizes unit, online, test-run a machine operating mode, any, the intelligent switching of no disturbance through the industry control host computer Direct Torque Control AC converter, PID control DC excitation loading system.
