Six-DOF (degree of freedom) carrier dynamic simulator

Abstract

The invention discloses a six-DOF (degree of freedom) carrier dynamic simulator. The dynamic simulator is composed of a real-time simulation computer and a movement control computer, a servo channel driver, a six-DOF electromechanical movement platform; each servo channel comprises a servo driver and an electromechanical actuator, the servo driver comprises a servo main loop frequency conversion power amplifying circuit module and a control loop circuit module, the electromechanical actuator is used for connecting a serve motor, a synchronous belt transmission box, a ball screw pair and a rotary encoder together. The six-DOF carrier dynamic simulator has the advantages that the modular structure is simple and compact, convenient for mounting, and simple in maintenance, the electromechanical cylinder improves the platform movement precision, a control scheme of a movement control card controls the position of each servo electromechanical cylinder, and greatly improves the precision and a limiting switch is built in to guarantee the ultimate safety; the full-digitalized closed loop servo control is used for guaranteeing the smooth transition of the movement and high simulation and reducing the dynamic drifting and distortion, the efficiency of the system is as high as 85%, and the application range of the simulator is wide.

Description

technical field [0001] The invention relates to a six-degree-of-freedom carrier dynamic simulator and belongs to the technical field of automatic control. Background technique [0002] At present, the traditional electric six-degree-of-freedom platform adopts a complex hydraulic and hydraulic cylinder system. Because of hydraulic oil leakage and regular replacement of hydraulic oil, the cost and installation and maintenance costs are high and do not meet the requirements of modern green environmental protection, and there are Due to the shortcomings of the platform, such as small load-bearing capacity, high noise, large space occupied by the overall equipment, low platform movement accuracy, and the inability to individually and accurately control the position of each servo cylinder, in addition, the traditional electric six-degree-of-freedom platform cannot guarantee the accuracy of the movement. Smooth transition and high emulation, dynamic drift and distortion are relativ...
