TEST VIBROPLATFORM Russian patent published in 2012 - IPC G01M7/02 G01V1/155 

FIELD: test equipment.

SUBSTANCE: invention refers to test equipment and can be used during testing of objects of mechanical engineering, construction industry, household appliances and other products for vibration strength and vibration resistance. The proposed test vibroplatform includes the base fixed on the foundation, horizontal table for arrangement of test products on it, and the table supports fixed on the base. Table supports provide the possibility of its horizontal vibrational displacement relative to fixed base. Vibroplatform also includes hydraulic actuator (vibration exciter of the platform), pump unit, electrohydraulic supply system of controlled flow of working fluid to vibration exciter (actuator), electric control system of vibroplatform operation and measurement of parameters of the table vibrations, pipelines and communication cables of hydraulic and electric units of vibroplatform. Table supports are made in the form of posts fixed on the platform base and vertically oriented flexible links, the upper ends of which are fixed on the posts, and lower ends are fixed on the table.

EFFECT: increasing the platform stability, uniform distribution of vibration parameters along the whole working surface of the platform and compactness.
