Description

technical field [0001] The invention belongs to the technical field of mechanical vibration and noise control, and in particular relates to a free boundary simulation device for horizontal vibration experiments. Background technique [0002] Vibration test experiment is a necessary means for the research of mechanical vibration and noise control technology, in which the simulation and realization of the boundary conditions of the tested part have a direct impact on the experimental results. In the common vibration test experiments, there are abundant means of simulating the boundary in the vertical direction, but the development of the free boundary simulating device in the horizontal direction is relatively lagging behind. This cannot meet the requirements of the horizontal vibration test experiment, which seriously restricts the research of three-dimensional vibration reduction and isolation technology. Contents of the invention [0003] In order to solve the problem th...
