First stage: control system issues activation signal driving pressurized strut 2 to hydraulic system and receives before executing in the first stage
Contracting, by driving the pressurized strut transmission shaft 17 being connected with driving pressurized strut 2 to slide along the sliding slot of pressurized strut slide bar 19.Pressurized strut
Slide bar 19 is fixedly connected by bolt with rocker arm 15, when pressurized strut transmission shaft 17 moves to 19 end of pressurized strut slide bar, and then band
Shake arm 15 to rotate around rocker arm shaft 3.Rocker arm 15 is connected by lower connecting shaft 13 with connecting rod 14, pushes connecting rod 14 to move, connecting rod
14 push simulation hatch door 11 to move.It is transported the simulation track as defined in the limitation lower edge of Track Point 8 and orbit wheel 12 of hatch door 11
It is dynamic.Equally, load slide bar 20 is fixedly connected by bolt with rocker arm 15.It loads slide bar 20 and passes through load transmission shaft 18 and spring shaft
22 are connected, and spring shaft 22 is driven to move to negative direction of the y-axis, and the compression for rear spring 26 is realized while movement.As
After dynamic cylinder transmission shaft 17 contacts 19 end of pressurized strut slide bar, it will continue to move under the drive that driving pressurized strut 2 is shunk and dial
Bar 21 contacts.After contact, driving lever 21 is rotated under the action of pressurized strut transmission shaft 17 around driving lever rotation axis 4.Driving lever 21 is rotating
During push sliding block 24 along spring shaft 22 slide.Sliding block 24 carries out preceding spring 25 into negative direction of the y-axis motion process
Compression；At the same time, sliding block 24 is disengaged with the convex block 28 on spring shaft 22, and load provided by preceding spring 25 does not just remake
For spring shaft 22.After sliding block 24 and spring shaft 22 disengage, simulation hatch door 11 moves to final locked position.This
When, the load that simulation hatch door 11 is born only is provided by rear spring 26, magnitude of load F1。
Second stage: driving pressurized strut 2 executes decompression function before second stage executes, at this point, driving pressurized strut 2 is no longer
Offer overcomes driving force；Simulating hatch door 11 keeps locked position at the end of the first stage constant.Since preceding spring 25 is no longer influenced by
External force, the preceding spring 25 in compressive state extends, while sliding block 24 being pushed to move along spring shaft 22 to y-axis direction.It is sliding
Block 24 drives driving lever 21 to rotate around driving lever rotation axis 4 during the motion.Pressurized strut transmission shaft is driven in 21 rotation process of driving lever
17 move in the slot 19 of pressurized strut slide bar.Sliding block 24 is moved to be contacted with the convex block 28 of spring shaft 22, the load of preceding spring 25
It is applied on spring shaft 22 by sliding block 24.Since the sliding slot of pressurized strut slide bar 19 is longer, make in 24 contact tab 28 of sliding block
Dynamic cylinder transmission shaft 17 does not move to the end yet.So the load that simulation hatch door 11 provides at this time is total to by preceding spring 25 and rear spring 26
With providing, magnitude of load is by F1Increase to F2。
