INVESTIGATION OF THE OSCILLATIONS AMPLITUDES BASES AND FOUNDATIONS OF THE FORMING MACHINE

English abstract

Dynamic load equipment is a source of waves that propagate in the ground and affect nearby buildings and structures. Objects with equipment that are sensitive to vibration and operating personnel are not infrequently exposed to vibrations that do not rarely exceed the values set by regulatory documents. The foundations of mold-ing machines from the influence of dynamic loads were studied experimentally, taking into account damage to the foundations. Also, the magnitude of the amplitude was influenced by the above mentioned soil properties, which arose during their operation, the physical and mechanical characteristics of the soil of the bearing lay-er, as well as the underlying layers. To measure the amplitudes of oscillations and sediments of the foundations of the molding machines used modern measuring equipment It is determined that the amplitude of oscillation of the base under study when the machine is almost 2.3 times higher than acceptable. And at work of all machines at the same time the amplitude of oscillations of a certain foundation 13.7 times exceeds the allowable one. The reason for the increased fluctuations of the foundations has been identified and substantiated. It was found that the foundations of the molding machines are made with deviation from the design decision (reduced size) and have damage during operation. Recommendations are given to remedy the identified shortcomings.
