Description

A kind of big pulsewidth waveform generation pilot system of open loop
Technical field
The utility model belongs to automation field, and in particular to a kind of big pulsewidth waveform generation pilot system of open loop.
Background technology
During aircraft landing, automobile stop the production and use that the Large-sized Communications tool such as stop, there are the short time Big pulsewidth overload effect.This overload has the rigidity of whole equipment bigger influence, especially in certain extreme environments In, the influence to equipment may be destructive.For these reasons, it is very necessary for the examination of Related product rigidity 's.A kind of big pulsewidth waveform generation pilot system of simple in structure, reproducible, overload and adjustable pulse width is needed, to examine Product rigidity under varying environment and reliability.
Utility model content
The utility model provides a kind of big pulsewidth waveform generation pilot system of safely, effectively open loop.
A kind of big pulsewidth waveform generation pilot system of open loop, including left and right track disposed in parallel, test platform pass through two Group wheel group disposed in parallel is engaged by clamping with left and right track respectively, and the roll-sliding on the track of left and right is arranged on test platform There is suspension tooling, hangs and fix test products in tooling;Test platform it is front and back respectively with transmission chain link, conveyer chain with transmission System connects;Driving device drives transmission system to work under control of the control system, and transmission system drives conveyer chain rotation, passes Chain haulage test platform is sent to move;Bearing is set in the track medial axis of left and right, waveform is installed on bearing Device, when test platform acceleration can be bumped against with waveshape generating device, the wave that generates after test platform and waveshape generating device collision Shape is consistent with the overload of process to be simulated in the horizontal direction is needed;Measuring system is to the speed of test platform, the items of impact Sensing data is measured and is recorded, and measurement result is transferred to control system, and control system is by controlling the driving device The speed of test platform is adjusted.
Preferably, brake is set in transmission system, and control system controls brake, is sent out by waveform The cooperation of generating apparatus hardness and brake speed, the test products that can be directed to different weight generate the overload of different tests demand.
Preferably, transmission system includes driving wheel and driven wheel, and driving device drives driving wheel rotation, driving wheel Drive conveyer chain rotation, pulling test platform roll-sliding in orbit
Preferably, waveshape generating device is made of spring and sleeve, and test platform and waveshape generating device bump against Spring in stroke speed and waveshape generating device of the waveform generated afterwards by adjusting test platform is completed.
Preferably, when fixed test products are overall structure in suspension tooling, test platform can directly be replaced.
The pilot system of the utility model design is bumped against by waveshape generating device and the test platform of movement to be generated and needs The identical overload of the equipment course of work to be verified, ensure that the reliability and accurate and effective examined for related door equipment.
Description of the drawings
Fig. 1 the utility model structure diagrams.
Specific implementation mode
As shown in Figure 1, pilot system, including left and right disposed in parallel occur for a kind of big pulsewidth waveform of open loop of the utility model Track 1, test platform 2 are engaged by clamping with left and right track 1 respectively by two groups of wheel groups disposed in parallel, and can be in left and right track 1 Upper roll-sliding.Left and right track 1 is similar to track for a train.
It is provided with suspension tooling 4 on test platform 2 and (if needs are identical as actual installation mode, floor installation can be used Form, fixed form is subject to experiment demand), hang fixed in tooling 4 test products 3 (such as test products are overall structure, Test platform can directly be replaced).The front and back of test platform 2 connect with conveyer chain 5 respectively, and conveyer chain 5 is connect with transmission system, drives Dynamic device 11 drives transmission system to work under the control of control system 13, and transmission system drives conveyer chain 5 to rotate, conveyer chain 5 Pulling test platform 2 moves.Transmission system includes driving wheel 10 and driven wheel 14, and driving device 11 drives driving wheel 10 to rotate, Driving wheel 10 drives conveyer chain 5 to rotate, the roll-sliding on track 1 of pulling test platform 2.
Bearing 7 is set in 1 medial axis of left and right track, waveshape generating device 8 is installed on bearing 7, works as examination Testing the acceleration of platform 2 can bump against with waveshape generating device 8, the waveform and quilt generated after test platform 2 and the collision of waveshape generating device 8 Examine the overload of the actual conditions of verification in the horizontal direction consistent.Waveshape generating device 8 is made of spring and sleeve, and experiment is flat In stroke speed and waveshape generating device of the waveform that platform 2 and waveshape generating device 8 generate after bumping against by adjusting test platform 2 Spring complete.
Measuring system 12 is measured and is recorded to the speed of test platform 2, every sensing data of impact, and will be surveyed Amount result is transferred to control system 13, and control system 13 is adjusted by controlling the driving device the speed of 11 pairs of test platforms 2.
Brake 10 is set on the driven wheel of transmission system, and control system 13 controls brake 10, can make Test platform 2 stops at an arbitrary position, preventing from plunging off the tracks during the rebound of test platform 2.
The pilot system of the utility model design is bumped against by waveshape generating device and the test platform of movement to be generated and needs The identical overload of the equipment course of work to be verified, ensure that the reliability and accurate and effective examined for relevant device.
The foregoing is merely an application examples of the utility model.Within the spirit and principle of the utility model, Made by any modification, equivalent replacement and transformation etc., should be included within the scope of protection of this utility model.
