Abstract

The invention discloses a mass center adjustable mixed type vibration damping platform. The mass center adjustable mixed type vibration damping platform comprises top platforms, a bottom platform, vibration damping units and mass center adjusting units, the plurality of vibration damping units are obliquely arranged between the top platforms and the bottom platform, one mass center adjusting unitis arranged between each vibration damping unit and the top platform, and the mass center adjusting units and the vibration damping units are arranged in the same axial direction; the mass center adjusting units comprise upper screw rods, sleeves and connecting rods, through holes are axially formed inside the sleeves, each of the top and the bottom of each through hole is provided with a thread section, the top ends of the upper screws are connected with the top platforms, the bottom ends of the upper screws are in threaded connection with threaded sections at the tops of the through holes, the top ends of the connecting rods are in threaded connection with the threaded sections at the bottoms of the through holes, and the bottom ends of the connecting rods are connected with the vibration damping units. The mass center adjusting units can realize platform mass center adjustment and pose adjustment, so that the mass center of a rigidity center and the mass center of a vibration damping system (including a vibration damping object and a rigid pedestal) are arranged on the same vertical line, and the vibration damping and vibration isolation effect can be greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of vibration damping platforms, in particular to an adjustable center-of-mass hybrid vibration damping platform. Background technique [0002] Vibration is ubiquitous in human production and life activities, and some vibrations are useful to human beings, such as vibrating screens. But most of the vibrations are useless or even very harmful to human beings, such as producing noise and causing serious accidents in production and life. Some precision instruments and equipment have extremely strict requirements on the environment, so it is necessary to take vibration reduction measures. In order to eliminate these useless vibrations, many methods of vibration reduction have been studied. Among them, some install isolation devices between the vibration source and the object to be isolated to achieve the effect of vibration isolation, some install damping devices to achieve the purpose of vibration elimination,...
