Abstract

The invention relates to the field of experimental devices, in particular to a double-mass gap nonlinear dynamics experimental device. The double-plastid gap nonlinear dynamics experiment device comprises an inner plastid, an outer plastid, a shearing motion assembly, a gap nonlinear assembly, a sensor assembly and a supporting assembly. The inner plastid penetrates through the outer plastid, and the inner plastid and the outer plastid are connected through the shearing motion assembly; the inner plastid is connected with one side of the gap nonlinear assembly, and the outer plastid is connected with the other side of the gap nonlinear assembly; the sensor assembly is used for measuring the acceleration time history of the inner plastid and the outer plastid in the horizontal and vertical directions; and the supporting assembly is connected with the inner plastid. The double-plastid gap nonlinear dynamic experiment device provided by the invention can conveniently and effectively perform a double-plastid gap nonlinear dynamic experiment, and can be used for performing experimental verification on an existing nonlinear dynamic theory.

Description

technical field [0001] The present application relates to the field of experimental devices, in particular to a two-mass gap nonlinear dynamics experimental device. Background technique [0002] Linear dynamics has been developed and perfected in both theoretical research and experimental research, and has been widely and fruitfully applied in engineering. However, for some practical problems that are beyond the scope of linear dynamics, nonlinear dynamics is a new topic developed based on this. At present, many important research results have been achieved on nonlinear vibration theory, which can effectively explain many nonlinear phenomena encountered in production. However, due to the lack of nonlinear experimental devices, experimental research on nonlinear dynamics lags behind theoretical research. hinder the development of nonlinear dynamics. Contents of the invention [0003] The purpose of this application is to provide a two-mass gap nonlinear dynamics experimen...
