Abstract

Изобретение относитс  к электротехнике и может быть использовано на стендах дл  испытаний двигателей внутреннего сгорани , трансмиссий вертолетов. Целью изобретени   вл етс  повышение быстродействи , точности регулировани  и расширение области применени . Устройство содержит измеритель 16 разности частот вращени  электрических машин, выход которого соединен с входом третьего элемента сравнени  18. Выход элемента сравнени  18 через регул тор 17 разности частот сравнени  подключен к входам регул торов 3 и 4 момента. В данном устройстве используетс  компенсирующа  св зь по моменту нагружени  и разности частот вращени  валов испытуемой передачи. 1 ил.The invention relates to electrical engineering and can be used on test benches for testing internal combustion engines and helicopter transmissions. The aim of the invention is to increase speed, control accuracy and expand the scope. The device contains a meter 16 of the difference in the frequency of rotation of electric machines, the output of which is connected to the input of the third element of the comparison 18. The output of the element of the comparison 18 through the controller 17 of the difference of the frequency of the comparison is connected to the inputs of the regulators 3 and 4 of the moment. This device uses a compensating connection according to the moment of loading and the difference in the frequency of rotation of the shafts of the test gear. 1 il.

Description

уровн  динамических показателей элект- ю щ е е с   тем, что, с целью повыше- ромеханических систем без упругих ни  быстродействи  и точности регули- звеньев, определ емого помехозащищен- 25 Ровани  момента нагружени  и расшиностью элементов, неполной управл емостью вентильных преобразователей и т.д., что позвол ет провести весь цикл испытаний механической передачи с требуемым быстродействием частоты вращени  и момента нагружени .Устройство может быть использовано дл  ширкого колеса электромеханических систем с упругими звень ми независимо от типа электрических машин и электрической схемы их соединени .Заранее известный вид процессов налаженного облегчает наладку устройства.The level of dynamic indices is electrified so that, for the purpose of amelio-mechanical systems without elastic speed and accuracy of adjustments, determined by the noise immunity of the load elements and the distance of the elements, the incomplete control of valve converters, etc. d., which allows to carry out the whole cycle of tests of mechanical transmission with the required speed of rotational speed and loading torque. The device can be used for the wide wheel of electromechanical systems with elastic links depending on the type of electrical machines and the electrical circuit of their connection. A well-known type of well-established process facilitates the setup of the device.
