[] The effective damping of vibration isolation bearings than isolated structures corresponding reciprocating or isolator and the isolation layer energy dissipation ratio of the effective damping and critical damping should be included in the effective damping and viscous damping, etc. isolation layer or isolator load borne by the ratio of the corresponding displacement of the effective stiffness and damping effect and its value is generally preferable to calculate the load-displacement curve of isolated structures horizontal damping coefficients corresponding secant stiffness level seismic shift points when reduction factor introduced by [more] isolation bearings under earthquake encounter between isolated and non-isolated buildings housing the largest layer of the layers to determine the ratio of shear isolation basic principle of active vibration isolation and passive vibration isolation in common is install damper (spring), but finished up security after damper isolation bearing manufacturers may make electronic products to protect the vibration is reduced. Vibration may also make more than the original. Therefore, you must understand the basic principles of vibration, or may get the opposite result. [Isolation] seat. When the composition of the role of the mechanical vibration of the object by the force of the disease alternating actuation system in a location near Levin reciprocate. The motor placed in a simple support beam, when the motor rotates, due to mass imbalance caused by the inertial force produced by the motor rotor is reciprocated up and down and left and right directions. When the left and right direction of movement restrictions, constitute vibration (sinusoidal vibration of single degree of freedom system) easiest vertically, as shown in 5-50 (a) below. [Isolation] one hundred million Bin Microelectronics motor mount on the simply supported beam, the center of rotation of the motor at 0:00, the rotor mass of mf, the focus shifted in the mouth point, eccentricity ', rotor angular velocity is m, When it is rotated, centrifugal force is generated in the rotor EJ, vertical component zJ is y2, the horizontal component of D :. [Isolation] bearing isolation technology development and the principles outlined in the traditional seismic system gradually cause the problems of earthquake engineering scholars think. In order to adapt the structure of the earthquake, in recent years, people are constantly looking for effective ways to resist earthquake damage, such as the development of new materials, research and other forms of new structures. [Isolation] bearing isolation technology is one of the hotspots of earthquake engineering practice. Now the research and application of more isolation technology is mainly sandwich rubber isolation and sliding isolation. However, most research studies limited to a single seat or a single advance sandwich rubber friction sliding bearing. Since the development of complex isolation system isolator relatively late, no one conducted in-depth research, design, and thus the lack of adequate data points. [Isolation] base isolation bearings are set isolation layer between the upper structure and foundation, through isolation system isolation layer to restrict incoming and absorb seismic energy structure. The following seismic response spectrum of the building to explain the principles of base isolation. Acceleration response spectra of ordinary buildings and displacement response spectra. As the general building rigidity, short cycle, so when a large vibration acceleration, and small displacement. [Isolation bearings can be seen from the above], to extend the period of the structure, where appropriate, HDR series of high damping rubber bearings, which can effectively control the acceleration of the building, if we give the structure an appropriate damping HDRB high damping rubber septum isolators sales, displacement structure can also be controlled within the allowable range. [Isolation] large displacement bearing structure is mainly provided by the isolation system between the bottom of the structure and foundation, so not only effectively weakened the seismic energy input structure, but does not cause structural deformation and destruction of excessive . This is the basic principle of base isolation HDRB high damping rubber bearing sales, isolator, manufacturers large supply provided by Hengshui Rubber Co. Guangrun.
