The invention discloses a
parallel motion simulation platform with a load-bearing mechanism. The
parallel motion simulation platform mainly comprises a basic platform, a motion platform, a load-bearing platform, six driving branches, a first load-bearing
branch and at least three second load-bearing branches, wherein the structures of the six driving branches are totally the same, and the structures of the at least three second load-bearing branches are totally the same; the six driving branches are connected with the motion platform and the basic platform, and thus a parallel driving mechanism is formed; the first load-bearing
branch and the second load-bearing branches are connected with the load-bearing platform and the basic platform, and thus a parallel load-bearing mechanism is formed; the six driving branches are all of UPS (Uninterrupted Power Supply) structures and are formed by electric cylinders, first ball hinges and first universal hinges; the first load-bearing
branch is of a UPU (Uninterrupted
Power Unit) structure and is formed by a balance
hydraulic cylinder or balance air cylinder, a second universal hinge and a third universal hinge; and the second load-bearing branches are of the UPS structures and are formed by balance hydraulic cylinders or balance air cylinders, second ball hinges and fourth universal hinges. According to the
parallel motion simulation platform disclosed by the invention, the
load bearing capacity is strong, the dynamic response speed is quick, the control is simple, the parallel
motion simulation platform is suitable for indoor and field environments, and additional load caused by the load-bearing mechanism is simultaneously reduced.
