Method of testing a construction structure on pliable supports with a spacing at excessive impact action

FIELD: construction. SUBSTANCE: invention relates to construction and can be used in testing elements or structures of buildings and structures for evaluation of stress-strain state under action of excessive short-term dynamic loads. During the method implementation, evaluation is performed by means of comparative analysis of test results of tested structure on pliable supports and similar structure on rigid supports at equal test conditions. Both structures are exposed to an excessive impact action and the beginning and the end of impact action are fixed. Instantaneous values of short-term dynamic load are measured using a force meter in a fixed time interval. Instantaneous values of accelerations and displacements of each building structure along its length are measured. Force of inertia is determined in fixed time interval proceeding from number of accelerometers, masses of sections and accelerations corresponding to arrangement of accelerometers. Instantaneous values of short-term dynamic load and value of inertial force are used to define force directed to deformation of each structure, and value of averaged deformation energy is determined from it and average value of structure displacement in time. Energy ratio is calculated from the ratio of averaged energy values, which is used to determine reduction of active energy to the building structure using flexible supports. Based on the energy directed to deform the support, and the total energy acting on the structure and supports, the efficiency of pliant supports application is assessed.

Hard bulkhead with a vibration level sensor is fixed on the base, two identical on-board compressors are installed on various vibration isolation systems and their amplitude-frequency characteristics are measured. One compressor is installed on the regular rubber vibration isolators, and the other compressor is installed on the analyzed two-mass vibration isolation system. Vibration level sensor is attached to the rigid bulkhead, said sensor is connected to an amplifier and spectrometer, then the first compressor is turned on and the amplitude-frequency characteristics of the system are taken, after which the first compressor is turned off and the second compressor, installed on the investigated two-mass vibration isolation system, is turned on. Amplitude-frequency characteristics are taken, then the obtained characteristics from the operation of each of the compressors are compared, and conclusions about the effectiveness of the vibration isolation of each system are made. To determine fundamental frequencies of each of the analyzed vibration isolation systems simulated are impact pulse loads on each of the systems with the help of a diagnostic impact device, comprising a body, piezoelectric dynamometer, impact element and additional mass. Additional mass of the diagnostic impact device is made in the form of a cylinder and placed above the main mass, which contains a cavity filled with rigid balls, which, in determining the fundamental frequencies of each of the analyzed vibration isolation systems, serve as a random stochastic impact imposed on the impact load.
