Double-shaft heavy-load swing test bench

Abstract

The invention discloses a double-shaft heavy-load swing test bench which mainly comprises a hanging basket type structure heavy-load swing test bench, a rotation driving mechanism and a rotation platform. The rotation driving mechanism and the rotation platform are installed on the hanging basket type structure heavy load swing test bench bottom plate, the test equipment is installed on the rotation platform, the rotation angle of the rotation platform and the swing angle of the swing platform are changed, and pitching, rolling and heaving motions of different sizes can be achieved at the same time only by installing the test equipment at a time. The three-degree-of-freedom motion of the test equipment under different working conditions can be truly represented, the preparation time for changing pitching, rolling and heaving motion of the test equipment is remarkably shortened, and the test bench has the advantages of being wide in working table top, high in bearing capacity, low in comprehensive gravity center and the like.

Description

technical field [0001] The invention relates to the technical field of a swing test bench, in particular to a biaxial swing test bench. Background technique [0002] The swing test bench is a space motion structure widely used to simulate the motion attitude of test equipment, and it has very important applications in the fields of ship motion and vehicle motion. With the continuous expansion of swing table technology in many fields, higher requirements are put forward for its bearing space, load capacity and attitude simulation. There is a new type of hanging basket structure heavy-duty swing test bench (ZL201710515748.9), whose structural feature is to use the structural form of the lifting lug as a load-bearing component, thereby reducing the offset distance and additional moment of inertia caused by its own weight, and improving However, due to the limitation of the single axis, only a single swing motion can be performed, and the pitch, roll and heave motion of the tes...

There is a new type of hanging basket structure heavy-duty swing test bench (ZL201710515748.9), whose structural feature is to use the structural form of the lifting lug as a load-bearing component, thereby reducing the offset distance and additional moment of inertia caused by its own weight, and improving However, due to the limitation of the single axis, only a single swing motion can be performed, and the pitch, roll and heave motion of the test equipment cannot be realized at the same time. At the same time, the test equipment needs to be reinstalled every time to change the installation position.
