Friction pendulum vibration isolation device and pressure monitoring structure thereof

Abstract

The invention discloses a friction pendulum vibration isolation device. A stainless steel diaphragm is inlaid in one side, which faces a sliding surface of a bottom support, of a bottom hinging slider; an alloy resistor is arranged on the stainless steel diaphragm and is integrally connected with the stainless steel diaphragm through molecular bonds, so that an alloy film strain unit, which is used for inducing vertical pressure of the support, of a Wheatstone bridge is formed; an external load acts on a top supporting slide seat or a bottom supporting slide seat to cause deformation of the alloy film strain unit; the alloy film strain unit generates a voltage signal for monitoring the vertical pressure of the friction pendulum vibration isolation device; and the sliding surface of a bottom support plate is a curved surface. The invention also discloses a pressure monitoring structure for the friction pendulum vibration isolation device. By the friction pendulum vibration isolation device and the pressure monitoring structure thereof, the stress condition of the friction pendulum vibration isolation device can be monitored in real time, so that the health condition of the friction pendulum vibration isolation device can be judged; the friction pendulum vibration isolation device is high in fatigue resistance, high in stability and small in size; and influence on the mechanical property of the vibration isolation device is low.

Description

technical field [0001] The invention relates to the field of vibration isolation devices, in particular to a friction pendulum vibration isolation device capable of real-time monitoring of health status and self-diagnosis function and its pressure monitoring structure. Background technique [0002] The currently widely used vibration isolation bearings mainly include lead rubber vibration isolation devices, high damping rubber vibration isolation devices and friction pendulum vibration isolation devices. However, due to the low vertical bearing capacity and poor durability of the bearings made of various rubber materials, they cannot be used alone in large structures with heavy upper structures and large horizontal displacement requirements. At this time, they need to be used Friction pendulum vibration isolation device. [0003] The friction pendulum vibration isolation device is an effective dry friction slip isolation system, which has good mechanical properties and can ...

Problems solved by technology

[0005] But at present, there is no equipment that can monitor the health of the support, or a vibration isolation device with a pressure monitoring function. Some people have tried to use sensors to detect the force of the vibration isolation device, but ordinary sensors cannot Put it in the vibration isolation device, even if it can be placed in the vibration isolation device, it will affect the force of the vibration isolation device and cause adverse effects
