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 impact-resistant vibration damping support based on a hydraulic principle and a working method. The impact-resistant vibration damping support comprises a cylinder body, a piston body and impact-resistant vibration damping support bodies on the two sides, wherein a buffer end is arranged in the piston body, and the buffer end and the piston body are connected through a spring and used for relieving or offsetting the impact effect of a drop hammer and the piston body at the beginning; and when the elastic deformation of the spring reaches the maximum, the impact-resistant vibration damping support bodies on the two sides start to work, hydraulic oil in the cylinder body flows into the impact-resistant vibration damping support bodies on the two sides, and when theelastic deformation of the spring reaches the maximum, the hydraulic oil is offset by the gravity of large-weight mass blocks on the two sides. The impact effect and the anti-vibration effect of thelarge-mass drop hammer on a test device or the ground can be relieved, then components are analyzed, the blank of the drop hammer impact test in the aspect is filled up, and the impact-resistant vibration damping support better conforms to the actual engineering general 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...
