The common disadvantages of the known dynamic platforms include low reliability, design complexity and limited functionality.

The technical task of the proposed utility model is to ensure the reliable operation of a dynamic platform while expanding functionality in a learning environment that is close to real, and

also the elimination of the disadvantages inherent in well-known dynamic platforms.

The problem is solved in that the dynamic platform contains a movable frame with a cab installed on it (simulator module) and a fixed frame with sliding supports, on which the drive, stand and stops are located, and is characterized in that the movable frame is connected to the fixed frame in a place corresponding to the center of mass (CM) of the simulated object, by means of a hinge with spaced intersecting axes, and a rack, the drive is made in the form of motor reducers, each of which is connected via a crank to a ball with fingers, prisoners with a movable frame, while on a fixed frame, a power supply and drive control unit.

The following graphic materials explain the essence of the proposed utility model.

Implementation of a utility model.

The dynamic platform comprises a movable frame 1 with a cab 2 installed on it (a simulator module) and a fixed frame 3 with sliding supports 4, on which the drive 5, the rack 6 and the stops 7 are placed, Fig. 1.

Unlike the known ones, the movable frame 1 is connected to the fixed frame 3 in a place corresponding to the center of mass (CM) of the simulated object, by means of a hinge 8 with spaced intersecting axes and a rack 6. The drive 5 is made in the form of motor reducers 9, each of which the crank 10 is connected by a rod 11 with the spherical fingers 12, fastened to the movable frame 1. On a fixed frame 3, an electrical cabinet 13 for supplying and controlling the drive 5 is installed.

The design of the dynamic platform (DP) is based on the principle of the location of the crew members of the simulated object relative to its center of mass and their movement in vertical (pitch) and horizontal (roll) planes when moving the object over rough terrain.

The farther from the center of mass (CM) of the simulated object is the center of mass of the cab 2 (simulator module), the higher the amplitude of its oscillations. The proposed utility model provides the ability to change the position of the CM of the cab 2 (relative to the CM of the simulated object) by moving it on the movable frame 1.

To ensure the movement of the movable frame 1 with the cab 2 installed on it (the simulator module) in two mutually perpendicular planes, a hinge 8 with spaced intersecting rotation axes is used, since it is structurally simpler and more technologically advanced to manufacture than devices used on known dynamic platforms (crosses) ball joints).

To implement the movable frame 1 of certain values of the pitch and roll angles, with given displacement speeds, drive 5 was used in the form of gear motors 9 with integrated sensors for controlling the angle of rotation of the shaft

electric motor, and for the transmission of reciprocating motion from the gearbox shaft 9 to the movable frame 1, a crank 10 is mounted on the shaft, which is connected to the movable frame 1 by rods 11 with spherical fingers 12.

Ball fingers 12 allow the rods 11 to transmit force from the gearmotors 9 to the movable frame 1 at any angle of inclination up to 20 degrees.

The fixed frame 3 is equipped with vibration mounts, which serve to ensure horizontal exposure of the DP in the room and prevent the transmission of vibration to the floor, and from tipping over at emergency angular speeds (more than 40%) - sliding supports 4 designed to increase the supporting arm and prevent the cab 2 from tipping over ( module-simulator) at a critical speed of movement of the movable frame 1, in particular, when the dynamic platform control program fails.

The work of the dynamic platform is as follows.

To develop the skills of trainees when driving on rough terrain, the crew takes jobs in cabin 2 (simulator module). At a command from the supervisor’s console, the signals through the control unit are supplied to the drive 5 according to the specified program. The electric motors of the gear motors 9 come into operation, transmitting the force through the crank 10, rods 11 and ball pins 12 to the movable frame 1, which oscillates according to a given program in the plane of pitch and roll.

To perform the roll, the shafts of the electric motors of the gearmotors rotate with the same number of revolutions in opposite directions transferring pushing forces to the cranks 10, and from them through the rods 11 with spherical fingers 12 to the movable frame 1, forcing it to rotate around the longitudinal axis on the hinge 8.

To implement angular movements in the pitch plane, the shafts of the electric motors of gear motors 9 with the same number of revolutions rotate in the same direction, transferring pushing forces to the cranks 10, and from them through the rods 11 with ball fingers 12 to the movable frame 1, forcing it to rise (lower ) in the vertical plane.

The design of the proposed dynamic platform provides a higher speed of the angular movement of the moving platform in comparison with the known ones and eliminates its rollover when the program fails.

When rotating the shafts of the electric motors of the gear motors 9 with a different number of revolutions, the movable frame 1 performs complex (in two mutually pre-perpendicular planes) vibrations (roll + pitch), the implementation of which provides enhanced functionality in training conditions close to real ones, as well as elimination of disadvantages peculiar to well-known dynamic platforms.
