The invention has the advantages of low cost, simple structure and convenient wiring, can simulate the layout in the cabin and the real electromagnetic environment of the helicopter, and meets the requirement of an electromagnetic compatibility test of the helicopter.
Description
Technical field
The present invention relates to a kind of platform of the analogue simulation for the electromagnetic compatibility experimental subjects, more particularly, relate to a kind of electromagnetic compatibility quick detecting platform for wire cable layout of helicopter.
Background technology
Need to set up a system test environment in the new machine development process of helicopter, to verify the property indices of its flight control system comprehensively, this experimental enviroment is called " iron bird " testing table, for example ARJ21 " iron bird " testing table, destroy-10 " iron bird " platform, F-22 drops into " iron bird " of test etc.Above-mentioned iron bird experiment table adopts the steel-tube construction framework, and its contour structures, size, in-built equipment etc. are all identical with real aircraft, and therefore the system health in most of practical flight can reproduction strictly according to the facts in the iron bird experiment table.But, for the experiment of helicopter electromagnetic compatibility, the rack construction of " iron bird ", material etc. all can not meet the specific (special) requirements of EMC test, and the construction cycle of " iron bird " testing table is long, cost is large; In addition, due to narrow and small crowded in the testing table cabin, all devices centralized arrangement, thus cause the cable difficulty of arranging, also to EMC test, bring very big inconvenience.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide that a kind of cost is low, simple in structure, electromagnetic compatibility quick detecting platform for wire cable layout of helicopter easily connects up.
For achieving the above object, electromagnetic compatibility quick detecting platform for wire cable layout of helicopter of the present invention comprises desktop 1, apparatus lifting device 2, wiring positioning groove 3, elastic stretching device 4, support 5 and carriage 6, the physical dimension of described desktop 1 is identical with helicopter prototype xsect, and be divided into a plurality of modules by the order of helicopter head, fuselage, desktop adopts modular design, has guaranteed the convenient and swift of split and assembling; Described apparatus lifting device 2 is subject to the height of measurement equipment for adjustment, installs on the table, and be hollow cubic body framework; Described wiring positioning groove 3 is subject to the measurement equipment cable for collection, is arranged on the position of desktop corresponding to body both sides, helicopter prototype cabin, is hollow rectangle shape long tube; Described support 5 is arranged on the desktop bottom, is bamboo joint type support that can be flexible up and down, for supporting desktop and adjustment height of table top; Between desktop 1 each module, by the elastic stretching device 4 be fixed between the support that supports this module, connect; Carriage 6 also is equipped with in described support 5 bottoms, is convenient to platform movement.
Electromagnetic compatibility quick detecting platform for wire cable layout of helicopter of the present invention has that cost is low, simple in structure, advantage easily connects up.The platform desktop adopts modular design, is convenient to split and assembling; Apparatus lifting device can be subject to according to the configuration requirement adjustment of helicopter below deck equipment the height of measurement equipment, the multi-level installation structure of helicopter simulating below deck equipment; Be positioned at the extension type support of desktop below, can adjust up and down the height of desktop, can meet and be subject to measurement equipment putting in cabin; And whole test simulation platform is unenclosed construction, make test convenient.In a word, in the situation that financial resources, material resources and experiment condition are limited, electromagnetic compatibility quick detecting platform for wire cable layout of helicopter of the present invention is than " iron bird " platform, and profile is simplicity generosity more, both cost-saving, layout and true electromagnetic environment in the helicopter simulating cabin fully again.

The outboard profile that Fig. 2 is electromagnetic compatibility quick detecting platform for wire cable layout of helicopter of the present invention.
Fig. 3 is the schematic diagram that the cable while utilizing the present invention to carry out EMC test is disposed.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Electromagnetic compatibility quick detecting platform for wire cable layout of helicopter of the present invention as shown in Figure 1 and Figure 2, comprises desktop 1, apparatus lifting device 2, wiring positioning groove 3, spring 4, support 5 and pulley 6.The physical dimension of described desktop is identical with helicopter prototype xsect, and is divided into 8 modules by the order of helicopter head, fuselage, and as shown in Figure 1, wherein, the size of going to the bottom on bottom is trapezoidal is respectively 800mm and 1900mm, and height is 600mm; Four rectangle specifications are 2000mm * 950mm; Go to the bottom and be respectively 700mm and 1900mm on middle part is trapezoidal, height is 1400mm; Afterbody rectangle specification is 2000mm * 700mm.Described apparatus lifting device 2 is subject to the height of measurement equipment for adjustment, installs on the table, and be hollow cubic body framework; Described wiring positioning groove 3 is subject to the measurement equipment cable for collection, is arranged on the position of desktop corresponding to body both sides, helicopter prototype cabin, is hollow rectangle shape long tube; Described desktop bottom is equipped with 26 supports 5, support 5 be can be flexible up and down the bamboo joint type support, for supporting desktop and adjustment height of table top; Between desktop 1 each module, by the spring 4 be fixed between the support that supports this module, connect; Pulley 6 also is equipped with in described support 5 bottoms, is convenient to platform movement.
Reflections affect electromagnetic wave produced for reducing metal material, desktop 1 and apparatus lifting device 2 adopt electromagnetic wave transparent material to make.Electromagnetic wave transparent material refers to that material itself do not have an effect to electromagnetic wave, as metallic composite.Electromagnetic wave transparent material is wood materials in the present embodiment.
While utilizing the present invention to carry out the EMC test of Helicopter System, the parts to be tested of helicopter are put the position in prototype according to it, can be adjusted up and down equipment in Zhong position, cabin by apparatus lifting device and support.With reference to going straight up to cabin inner cable layout, will test cable and be arranged in wiring positioning groove, be arranged in the platform desktop left and right sides, launch in the form of a ring, as shown in Figure 3, in figure, 3 is wiring positioning groove, 7 is associated cable.Then using this platform as the experimental subjects of electromagnetic compatibility, in the helicopter simulating cabin, layout and true electromagnetic environment, to be applicable to EMC test, realize the electromagnetic compatibility test to major equipment in cable and other cabins.
