40th, six-component sensor and the composition one of low temperature air chamber terminal pad 41, then by six-component sensor and counter-balanced carriage terminal pad
Screwed hole and counterweight bearing frame 36 on 39 are linked into an integrated entity, and six-component sensor is then directly pressed with low temperature air chamber terminal pad 41
On low temperature air chamber 14.Counterweight load maintainer 3 subtracts the plate number of balancing weight 37 by adding to change institute in air spring process of the test
The static load size of needs.Then by six-component sensor 40 come the dynamic load situation of air spring during testing experiment.
Six-freedom motion is carried out because 6-dof motion platform 6 can drive low temperature air chamber 14, therefore counterweight load maintainer 3
In the easy falling test stand of motion process, cause casualties, thus it is double with I, II, III, IV, V, VI welded type in the present invention
Oscillating bearing connecting rod 2 couples together counterweight load maintainer 3 and catenary motion supporting upright post 1 using ball pivot, so as to ensure examination
Test during platform, counterweight load maintainer 3 only has catenary motion, do not produce the motions such as inclination yaw.
Specific process of the test of the invention is described as follows：
1st, during on-test, 6-dof motion platform 6 is controlled, one will be fallen under 6-dof motion platform loading plate 9
Positioning is put, and testing crew opens the air spring 15 that upper-end closing plate 23 is put into experiment.By the air inlet of air spring 15 and transfiguration
The tracheae for measuring gas receiver 7 is connected.Then low temperature air chamber 14 is sealed up with upper-end closing plate 23.According to the car weight of desired simulation, pass through
Height of oil controller 25 adjusts the inside machine oil quantity of gas receiver 24, and then realizes the control to air containment.Ensure in the load
The height and rigidity of the air spring under lotus.
2nd, 6-dof motion platform 6 is controlled, 6-dof motion platform loading plate 9 is raised, until adjustable counterweight adds
When mounted mechanism supporting upright post 4 is not subjected to counterweight 3 gravity of load maintainer, control rack-and-pinion operating mechanism 28 slides two-side supporting
Pillow 27 is away from 6-dof motion platform 6.
3rd, cooling cycle system is opened, normal assays process is carried out.
4th, experiment is finished, and first controls rack-and-pinion operating mechanism 28, and two-side supporting ram 27 is put down to six-freedom motion
Platform 6 is close to, until stopping when can undertaking counterweight 3 gravity of load maintainer.Then 6-dof motion platform carrying is slowly fallen
Plate 9, untill six-component sensor and low temperature air chamber terminal pad 41 and low temperature air chamber 14 depart from.
