Description

High-speed dynamic test is roll actuating system for platform based on phase transition energy storage Technical Field The invention belongs to the technical field of high-speed dynamic test platforms, and particularly relates to a rolling driving device for a dynamic platform based on phase change energy storage. Background The current multiaxial gesture simulation system for equipment test has obvious short plates on core performance and application suitability, and cannot meet the requirements of high-dynamic and high-comprehensive tests, and the specific problems are as follows: firstly, the existing high-speed dynamic test platform takes a rocket engine as a rotary driving source, adopts the traditional layout of a tested device embedded into a skid body, wherein the tested device is fixed on a skid main body through connecting points at the front end and the rear end, and only an executing mechanism capable of rotating in the transverse rolling direction is arranged between the two. The design results in that the system can only realize dynamic/static gesture simulation in the transverse rolling direction essentially, and the rocket engine driving mode has obvious defects that the controllability and the accuracy of rotation driving are insufficient, and particularly, the accurate simulation of complex dynamic gestures such as uniform angular speed rotation and the like under the conditions of variable angular speed and variable load cannot be completed, and the gesture simulation capability is single and the accuracy is limited. Secondly, other similar gesture simulation systems are mostly suitable for ground static working scenes, have the problems of large volume and large overall mass, are required to be supplied with rotary driving force by depending on ground equipment, cannot be completely adapted to the carrying requirement of a high-speed dynamic test platform with the running speed not less than 500km/h, and cannot be further adapted to the high-speed dynamic application environment with the running speed more than 500 km/h. The electromagnetic rotary driving-based attitude simulation system has the advantages that the carrying capacity and the torque output value of the electromagnetic rotary driving-based attitude simulation system are far lower than those of a hydraulic driving system with the same volume (volume or mass), the carrying requirement of a high-speed skid cannot be met, the high-carrying and high-torque output requirement required by the performance verification of large-size and large-mass tested equipment is difficult to meet, and meanwhile, the electromagnetic system is poor in adaptability to severe vibration and impact environments generated in the high-speed running of the skid and is prone to functional failure. Table 1 major requirements for the Multi-axial pose simulation capability of the Equipment under test for technology and equipment development In a comprehensive view, the existing gesture simulation system cannot completely meet the current and future test requirements, on one hand, the large envelope gesture simulation capability represented by three large gesture angles of roll, pitch and yaw and high angular velocity is lacking, the multi-axis comprehensive dynamic/static gesture accurate simulation of large-scale tested equipment in the high-speed motion process cannot be realized, and on the other hand, the complex dynamic gesture simulation capability such as multi-axis linkage, rotation angle speed variation, uniform angular speed rotation under load variation and the like cannot be realized, and the core index requirement of the multi-axis test cannot be met. This directly results in that high-load and high-dynamic tests such as a high-speed ejection life-saving test based on a real front fuselage cannot be carried out, and the comprehensiveness and actual combat level of the test are severely restricted. In the prior related patent technology, as disclosed in a patent document (CN 120928836A), a posture control power system based on carbon dioxide phase change gas storage is not a patent related to a posture simulation system, but a patent related to an aircraft posture control power system. The core innovation of the patent is to utilize the carbon dioxide phase-change gas storage technology to quickly convert liquid carbon dioxide into gas state through exciting the medicine, provide a high-efficiency, low-cost and easy-to-operate power source for controlling the attitude of the aircraft, and solve the problem that the existing attitude control system is difficult to consider in the aspects of quick response, high specific impulse, low cost, convenience in operation and the like. Therefore, the patent document does not relate to the simulation capability of three attitude angles of roll, pitch and yaw, the multi-axis comprehensive dynamic/static attitude accurate simulation of large-scale tested equipment in the high-speed motion process, multi-axis
