Problems solved by technology

However, the mechanical structure is complicated, and 32 redundant drive motors are controlled at the same time, which increases the difficulty of control
Chinese patent 98102675.3 discloses a simulator with a weight-bearing actuator, which uses seven actuators to drive the platform movement and has a high load-carrying capacity, but the seven actuators form a redundant drive, and the system pressure needs to be detected in real time control, increasing the difficulty and cost of control

Embodiment Construction

[0014] In such figure 1 As shown in the schematic diagram of the structure of the six-degree-of-freedom heavy-load static balance parallel motion simulation platform, among the six drive branches with the same structure, the electric cylinder 3 is connected to the motion platform 5 through the first spherical hinge 4, and is connected through the universal hinge 2 Connect with basic platform 1. The connection of the center points of the above six first spherical hinges forms a semi-symmetric hexagon, the connection of the center points of the above six universal hinges forms a semi-symmetric hexagon, and the connection of the center points of the six first spherical hinges forms a semi-symmetric hexagon. The short side of the polygon corresponds to the long side of the semi-symmetrical hexagon formed by connecting the center points of the six universal hinges. The hydraulic balance cylinders 9 in the three load-bearing branches with the same structure are connected to the base...

Abstract

A double parallel type heavy-duty static balance motion simulation platform mainly comprises a motion platform, a base platform, a load-bearing platform, six driving branches and three load-bearing branches, wherein the six driving branches are completely identical in structure, and the three load-bearing branches are completely identical in structure. The motion platform, the base platform and the driving branches connected with the motion platform and the base platform constitute a parallel driving mechanism. The load-bearing platform, the base platform and the bearing branches connected with the load-bearing platform and the base platform constitute a parallel load-bearing mechanism. Each of the six driving branches is in an uninterrupted power supply (UPS) structure and is composed of an electric cylinder, a first spherical hinge and a universal hinge. Each of the three load-bearing branches is in a strategic petroleum reserve (SPR) structure, and is composed of a balance hydraulic cylinder or a balance air cylinder, a second spherical hinge and a rotational joint. The load-bearing platform is connected with the motion platform through a third spherical hinge. The double parallel type heavy-duty static balance motion simulation platform is strong in bearing capacity, quick in dynamic response speed, simple to control, and suitable for indoor and field environments, and simultaneously reduces extra load caused by the load-bearing mechanism.

Description

Technical field [0001] The invention relates to a parallel mechanism, in particular to a parallel motion simulation platform. Background technique [0002] A common six-degree-of-freedom parallel motion simulation platform is composed of six telescopic links, a base and a motion platform. The telescopic connecting rod is composed of an electric cylinder or a hydraulic cylinder. When the telescopic rod is an electric cylinder, the simulation platform has the advantages of strong overload capacity and easy to achieve high-precision servo control, but its output force is limited, and it cannot simulate the movement of large equipment such as airplanes and ships; when the telescopic rod is hydraulic When using a cylinder, the simulation platform can withstand heavy loads, but the large hydraulic system, easy leakage of components, high maintenance costs, and temperature sensitivity restrict its application in parallel motion simulation platforms. [0003] The continuous developmen...
