Finite Element Modelling of Rubber-Metal Vibration Isolators with Holes for the Vibration Protection System of Buildings

Blog Article

The article presents a calculation of rubber-metal vibration isolators with five holes of different diameters using a software package that implements the finite element method.A comparative analysis Horizontal Sensor of the Eigen frequencies of rubber-metal vibration isolators with five holes (one in the center, 4 symmetrically at the corners) and without holes is presented.Finite element models of a rubber-metal vibration isolator with and without holes are modeled, and their characteristics are analyzed.

The results show that vibration isolators with several symmetrically located holes have several Bottle Openers advantages in a number of parameters to vibration isolators without holes, and, therefore, can be used for vibration isolation of buildings, especially in the case of delayed installation of vibration protection.
