Problems solved by technology

[0003] However, since most of the test devices are rigid, it will inevitably cause impact on the test device or the ground when using a large-mass drop weight for testing. The impact will cause the overall vibration of the test device, and the results collected by the experiment will have large deviations.

Abstract

The invention discloses an anti-shock and vibration-absorbing support based on a hydraulic principle and a working method. The invention includes a cylinder body, a piston body, and anti-shock and vibration-absorbing supports on both sides; the piston body has a buffer end, a buffer end and a piston There is a spring connection between the bodies, which is used to alleviate or offset the initial impact of the drop hammer and the piston body; when the elastic deformation of the spring reaches the maximum, the shock-resistant and vibration-absorbing supports on both sides begin to work, and the hydraulic pressure in the cylinder The oil flows into the anti-shock and vibration-absorbing bearings on both sides, and when it reaches the maximum, it is offset by the gravity of the large-weight mass blocks on both sides. The device can slow down the impact and anti-shock effect of the large-mass drop hammer on the test device or the ground, and then analyze the components, filling the gap in the study of the drop weight impact test in this area, and more in line with the actual engineering situation.

Description

technical field [0001] The invention belongs to the field of anti-shock bearings, and in particular relates to an anti-shock and vibration-absorbing bearing based on a hydraulic principle and a working method. Background technique [0002] In addition to static loads, buildings must also bear dynamic loads during use. Among them, the influence of impact load is particularly important, and the impact load test of structural members is usually carried out by using a drop weight impact test device. [0003] However, since most of the test devices are rigid, it is inevitable that the test device or the ground will be impacted when a large-mass drop weight is used for the test. The impact will cause the overall vibration of the test device, and the results collected in the experiment will have large deviations. Contents of the invention [0004] The object of the present invention is to overcome the above disadvantages, and provide a shock-resistant and vibration-absorbing sup...
