(RU 2248548 C1, G01M 7/06, publ. 20.03.2005).

The disadvantage of all known designs is the lack of versatility, low reliability of devices, the complexity of their operation and repair.

The task to which the technical solution is directed is to create a reliable, relatively easy to operate and repair universal vibration bench for testing the structures of buildings and structures, models - models, fragments and their constituent structures and equipment under various conditions of dynamic loading.

At least a part of the frame structure bonds can be made rigid or flexible, or a part of the frame structure bonds is flexible and a part is rigid.

The vibration stand may additionally contain inclined, including intersecting, connections and / or communication diaphragms, allowing you to adjust its dynamic properties.

The technical result achieved by the claimed technical solution is the creation of a reliable, relatively easy to operate and repair vibration shaker, while reducing the cost and increasing its reliability as part of the work on experimental evaluation and confirmation of the dynamic stability and seismic resistance of structures, their joints, equipment. The favorable properties of the vibration stand are achieved by eliminating the need for the obligatory use of expensive vibration platforms, increasing the variability of load simulations of buildings and structures of various types and design solutions while saving energy by making the vibration source removable, and the vibration stand solid or removable, resulting in the possibility of regulation frequencies and amplitudes of the oscillations generated by him within predetermined limits. Using the vibration bench in practice allows us to bring the test conditions closer to real loads that arise at the time of seismic activity and other alternating influences, including when exposed to the pulsating component of the wind load, and to obtain more complete data on the stability and vulnerability of the tested structures. At the same time, tests can be carried out at any site and plant, by delivery and installation of vibration equipment with a stand to the place of the planned tests.

The main property that determines the reliability and safety of the test structure or attachment under the influence of dynamic loads is its ability to maintain certain operational properties, characterized by extreme conditions (controlled values of forces, displacements, etc.) in comparison with the regulatory requirements established in the technical regulations of national standards and other regulatory and technical documents developed in their development.

The limiting state of the work of structures or equipment during dynamic exposure is divided into two groups:

- the first group includes limiting states that lead to complete unsuitability for the operation of the test structure or equipment or to complete or partial loss of the bearing capacity of their main elements and fixtures;

- the second group includes limit states that impede the normal operation of the structure or equipment.

The limiting states of the first group are characterized by:

- the destruction of the mounts and elements of the test structure or equipment of any nature - plastic, brittle, fatigue;

- loss of stability of the form of the constituent elements of the structure or equipment, leading to its complete unsuitability;

- loss of stability of the position of the elements and nodes of the connections of structures or equipment;

- the transition of a structure or equipment in whole or in part to a variable system;

- a qualitative change in the configuration of the structure or equipment;

- other phenomena in which there is a need to stop operation, for example, excessive deformations as a result of shear in joints, opening of joints, etc.

All of the above parameters can be studied using a vibrating stand. The direct determination of the standardized values of quantitative and qualitative characteristics corresponding to the limiting conditions of a particular design or equipment with respect to which tests are carried out are the subject of special studies.

The vibration bench is additionally equipped with a specialized measuring and computing complex for collecting (not shown in the drawings), converting, registering, processing, transmitting and presenting information from sensors.

The technical solution can be illustrated by the embodiment of the vibrating stand and a description of the operation of the device.

The dynamic test bench is a specially made frame structure made in the form of a spatial spatial structure of metal rolling elements with rigid and flexible connections that mimic the work of the building's supporting system (walls, columns, floors).

The bottom of the structure is attached to the foundation base, rigidly or flexibly, depending on the task and the requirements of the test program. A vibration source is mounted on top of the structure, for example, an inertial vibration machine for horizontal dynamic loading. If necessary, the stand can be installed on existing vibration and seismic platforms.

Test structures or equipment, for example, fragments of walls, partitions, curtain walls, other elements, parapets, etc., are suspended or built into the structure.

During vibrations, the vibrostand and the test structure enter resonance simultaneously or in a fan manner. Oscillations arise in various elements of the equipment under test - accelerations and movements of a certain frequency, which are recorded by special measuring equipment. With appropriate accelerations and displacements and frequency, damage is recorded, the nature and level of development of which after comparison with current loads and other controlled indicators, for example, maximum displacements of structural units, resonant characteristics of equipment, which makes it possible to obtain objective conclusions about dynamic stability, reliability, seismic resistance and safety test design or equipment.

Elements of the frame structure, including sections, quantity, mounting points, methods of their connection, for example, rigid welding, flexible - using bolts, as well as installation methods of the equipment under test are selected according to the results of preliminary calculation analysis and compliance with similar conditions in order to simulate the operation with the maximum degree of reliability “building - connection - construction or equipment” systems under seismic and other dynamic influences.

The registration and measurement of signals is carried out using a specialized measuring and computing complex, for example, type MIC - 036 or other similar equipment designed to collect, convert, register, process, transmit and present information coming from sensors. Such equipment should provide measurements of the corresponding characteristics in a predetermined range of frequencies and amplitudes of oscillations.

Using a vibrating stand provides the following functions:

- as much as possible reliable imitation of the structure under dynamic (seismic) impact;

- excitation, measurement, registration and provision of primary processing of signals, frequency, discrete and others, obtained as a result of tests;

- display of measured values or converted parameters on the monitor;

- fixing the quantitative and qualitative characteristics of the limiting state of the structure or equipment and their constituent elements obtained as a result of testing;

- monitoring of measured values or converted parameters; assessment of the results of their measurement and transformation;

- self-diagnosis of measurements, including performance analysis with the ability to call diagnostic programs.

To measure accelerations, vibration frequencies, and also dynamic displacements, special sensors are used, for example, accelerometers AT 1105 - 10 m, which are installed near the source of excitation of vibrations, on the elements of the bench and the test structure.

The location of the sensors is selected based on the following conditions:

- places where, according to the results of calculations, the development of maximum stresses and strains is expected;

- the ability to simultaneously determine relative deformations in different coordinate planes;

- the ability to simultaneously obtain data of the oscillatory process synchronously from the source of excitation of vibrations, structures of the vibration stand and on the test structure, for the possibility of their comparative analysis.

The total number of monitored points and the number of sensors is not limited.

To create dynamic effects, at least one source of vibration or forced vibrations is used, for example, an inertial vibration machine such as VID-12 / 08M and other similar equipment. The main requirement is that the source of dynamic vibrations be able to create the necessary values of the exposure parameters in a wide range of frequencies and inertial loads by exciting mechanical vibrations in at least one horizontal or vertical plane.

The vibration source is controlled, as a rule, from a control panel located at a distance from the vibration stand.

If there is no overlap on the stand, the oscillation source is mounted on a vibrating stand, relying on special metal box-shaped or other beams on top of the two box-shaped beams by welding, bolts or otherwise. Beams are welded to the frame structure or fixed in another way, ensuring their rigid fastening.

All elements and fixtures have the necessary margin of safety for the perception of the planned dynamic loads.

Test Methodology

Field tests of structures and equipment are carried out by vibration or resonance method, which allows quantitatively measuring the power load simulating seismic effects in a wide frequency range.

According to vibration tests for specific levels of loading, the amplitude-frequency characteristics of the test fragment, the elements of the test structures are constructed, which represent the dependence of the vibration amplitudes of the structure on the frequency of harmonic influence.

By changing the frequency of the impact, dynamic characteristics are evaluated, for example, the frequencies of the fundamental tone of vibrations, dissipative properties, etc., as well as the fundamental nature of the operation of the “vibration stand - tested design” system. According to the test results, quantitative and qualitative indicators of the results of exposure, such as deformation, the nature and level of damage, are recorded.

The resulting damage, the magnitude of the efforts and deformations, dynamic characteristics are compared with the calculated values and / or standard parameters, as well as with each other, as a result of which conclusions are drawn about the reliability and safety of the tested structure or equipment.

At the same time, the initial dynamic characteristics of the vibration bench and test specimens are determined in advance in order to select the most optimal test regime from the point of view of the tasks being solved. Such tests are carried out, for example, by pulling the upper point of the vibration bench and the test structure or in another way, for example, by turning the vibration source on and off, recording the mode of vibration damping before the start of the entire test cycle, during the test, and after its completion. The resulting frequencies and periods of oscillation are also compared with the calculated values.

Simultaneously with the determination of dynamic characteristics, the initial technical state of the structure is recorded, for example, the absence or presence of damage, their nature, size of cracks, joints, etc. These characteristics are also further used in the analysis of test results.

The parameters of dynamic loading are assigned according to the results of the calculation analysis, taking into account the initial dynamic characteristics of the prototypes and are specified at the stages of testing.

The stages of loading are chosen so as to be able to pass the resonance system from the building to the test structure or equipment, and separately for the test structure or equipment.

A phased change in the level of loading is carried out by adjusting the operation of the vibration source. The loading time is determined when setting the test program.

Using the proposed vibration bench allows you to maximize the needs of researchers when assessing and confirming the conformity of structures and attachments to the requirements for reliability and safety by calculation and experimental means.

Comprehensive data obtained from the results of this analysis make it possible to express an objective judgment on earthquake resistance, dynamic stability of structures and equipment of buildings and structures.

Thus, the cost of testing is reduced by eliminating the need for expensive testing equipment, bulky vibration and seismic platforms, and increased variability of simulated loading of buildings and structures is achieved while saving electricity by making the vibration source removable and portable. The use of a vibration bench with the indicated characteristics makes it possible to bring the test conditions closer to real loading, inherent in alternating influences, probable during natural and technogenic phenomena, such as the effects of wind pulsations, traffic, etc., to obtain more complete data on the structural reliability and safety of structures and / or equipment in dynamic loading mode.

The proposed device is also characterized by ease of operation and maintainability, reliability and versatility.
