Abstract
Provided is a loader that can realize non-contact loading, wherein a loading magnetic pole is made from magnetic materials as silicon-steel plate, and the like, and a magnetic return path is formed between the loading magnetic pole and an object to be loaded. In accordance with a load requirement, a coil current on the loader is controlled by a constant flow source to change electromagnetic field between the magnetic pole and the object to be loaded, thereby controlling the load. The non-contact loader can not only realize non contact loading, but also can perform dynamic control and monitoring of a loading force conveniently, and is particularly suitable for a rotating rotor.
Description
Affiliated technical field
The present invention relates to a kind of contactless charger, especially can give the loader of rotor imposed load.
Background technology
At present, loader commonly used in slow test is the hand-hydraulic loader that general industry is used, and the single effect and the beidirectional hydraulic pressure loading device that design for structural test are specially also arranged.Hydraulic pressure loading device is generally fluid pressure type and loads, and partly is made up of oil cylinder, piston, connecting rod, oil pump etc.The hydraulic oil that will have a certain pressure with high-pressure oil pump is pressed into the operating cylinder of hydraulic pressure loading device, makes it to promote piston, to the structure load application.Payload values is tried to achieve by oil pressure gauge indicating value and loader piston compression area, also can directly be surveyed by the dynamometer of being put between hydraulic pressure loading device and the load heavy frame and read; Or with sensor signal is defeated by electronic scales and shows, also can be by the direct record of register.
There are shortcomings such as hydraulicefficiency is low, noise is big, cost is high, leakage contaminated environment in above-mentioned loader.And require loader and structure contact position to be designed with surface in contact, but surface of contact not necessarily is convenient to design in the position that some structure need load.In addition, the contact position of rotational structure is dynamic change, loads for the hydraulic pressure loader and has also brought a lot of difficulties.
Summary of the invention
Complicated in order to overcome existing hydraulic pressure loading device drive mechanism; The deficiency that loader and structure must contact; The invention provides a kind of contactless loader; This loader can not only be realized contactless loading, and can dynamically control and monitor loading force very easily, and is particularly suitable to rotor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of contactless loader; Comprise loading magnetic pole, controller and power supply, load on the magnetic pole and be wound with the enamel insulated wire circle that power supply is connected with enamel insulated wire circle on the loading magnetic pole; Can adjust coil current through power supply; And load between the object and form magnetic circuit, produce electromagnetic force, realize contactless loading.
Said loading magnetic pole can be processed by permeability magnetic materials such as siliconized plates.
The enamel insulated wire loop current that loads on the magnetic pole is controlled.Controller is connected with power supply, through controller power supply is controlled, with the adjustment coil current.
This contactless loader also comprises a Hall element, can measure magnetic induction density in real time.Hall element is loading magnetic pole and is loading between the object, and is connected with controller through signal wire, and Hall element is delivered to controller with the magnetic induction density that records through signal wire, and controller is analyzed and controlled electromagnetic force.
The invention has the beneficial effects as follows, can not change the loading object, apply static state, dynamic load easily.And can realize moving or the loading of rotating object.System is made up of electrical system, and no machinery and oil gear have the reliability height, and dynamic response is fast, advantages such as cleanliness without any pollution.

Embodiment
As shown in Figure 1, load magnetic pole 4 and link to each other with power supply 3, controller 2 links to each other with power supply 3, and Hall element 5 and controller 2 link to each other through signal wire.Process U-shaped with permeability magnetic materials such as siliconized plates and load magnetic pole 4, and load magnetic loop of formation between the object 1.Twine enameled wire loop on the magnetic pole, coil links to each other with controlled constant-current supply 3.It is fixing and and load between the object 1 and leave certain interval that U-shaped loads magnetic pole 4.When constant-current supply 3 requires according to load to coil will generate an electromagnetic field between U-shaped loading magnetic pole 4 and the loading object 1 behind the logical corresponding electric current.Electromagnetic force can be passed through Hall element 5 measurements and monitoring, thereby reaches the purpose that noncontact loads.
As shown in Figure 2, loading magnetic pole 4 longitudinal profiles is E shape, and it is formed by E shape silicon steel plate stacking, on magnetic pole, is wound with the enamel insulated wire circle.Load magnetic pole 4 and be fixed on 1 correspondence position of loading object.
