Problems solved by technology

Existing motors have a large radius, and in the case of a specified displacement, the volume is large and the space occupation is large, which is not conducive to installation in some occasions. When the speed is low, due to insufficient centrifugal force, a good closed volume cannot be formed, and the sealing performance is not good. it is good

Abstract

The invention provides a two-degree-of-freedom four-motor driving rotating table. The two-degree-of-freedom four-motor driving rotating table comprises a rectangular support framework, a first rotating shaft, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, a first motor, a second motor, a third motor and a fourth motor, wherein the first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft are separately mounted on the four edges of the rectangular support framework, the first motor, the second motor, the third motor and the fourth motor are separately mounted on the first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft, and the motor can drive the rotating shafts to rotate.

Description

technical field [0001] The invention belongs to the field of load simulation experiments, and specifically relates to a two-degree-of-freedom four-motor-driven turntable, which is a device for rotating an auxiliary system designed to simulate the mechanical environment of a real engine under laboratory conditions. Background technique [0002] The auxiliary system designed to simulate the mechanical environment of a real engine under laboratory conditions consists of a main body, a loading system, and a liquid-gas energy system. The large inertial body of the body simulates the moment of inertia of the engine, and the spring plate simulates the frame stiffness of the engine. The servo mechanism, loading system and other equipment are all installed on the load table body. The engine servo mechanism is installed on the table body perpendicular to the ground, and the linear motion of the piston rod of the servo mechanism pushes the rotating shaft to swing through the force arm...
