Description
Technical field
The utility model belongs to helicopter dynamic flying analogue technique field, and in particular to is used for helicopter dynamic flying mould
The roll freedom of quasi- device turns round stop mechanism.
Background technique
Helicopter Dynamic Flight Simulator is a kind of simulation training system based on centrifugation machine platform.Sustained load can be achieved
Any Three Degree Of Freedom attitudes vibration in the space of lower pilot, easily induces a variety of spatial disorientations, can be in ground environment Imitating
A variety of exception state of flights, have reached and allow pilot's cognitive orientation obstacle, grasp the environment, the form of expression that disorientation occurs with
And conquering method.
Space three-freedom is yaw, rolling and pitch freedom, and yaw freedom is driven by motor yaw frame and realizes, rolling
Turn freedom degree and the realization of rolling frame is driven by motor, cockpit realization is driven by motor in pitch freedom.
Before starting to train pilot, pilot need to enter cockpit by ladder or other tools.Therefore the upper machine of pilot
When need flight simulator to keep original state, yaw frame, rolling frame do not generate relative motion between cockpit, in order to avoid cause to fly
Office staff's fallen accident.
The flight simulator axis driving for being typically based on centrifugation machine platform can match electromagnetic brake or hydraulic using direct driving motor
Brake, in system quiescence, brake operation can guarantee that each axis does not generate relative motion.But motor, brake needs are non-
Calibration system, volume weight is big, and installation space is caused to be restricted.The rotary inertia of system, thus motor driven function are increased simultaneously
Rate and torque also need to further increase, and turning mount structure also needs to further enhance, and ultimately cause system scale increase, cost is at multiplication
Add.Therefore electromagnetism or liquid braking device are suitable for large-scale flight simulator.And motor and the retarder driving of goods shelf products are used,
Product cost can be greatly reduced, but the braking moment that motor carries is insufficient, when the upper machine of pilot, rolling frame and yaw frame
Between there may be relative motions, fallen accident may be caused, cause security risk.Therefore special stop mechanism need to be designed.
The torque radius yawed between frame and rolling frame is smaller, and load is larger, therefore it is biggish only to design bearing strength
Motivation structure.
We has developed a kind of roll freedom for helicopter Dynamic Flight Simulator in order to solve problem above
Turn round stop mechanism.
Summary of the invention
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of for helicopter dynamic flying mould
