The calculation analysis of radial shock absorbed for conteiner subjected emergency falling

The article is considered the calculation method of the damper properties protective radial shock absorber for container. It is necessary destroying damage minimization of goods in the process of emergency falling connected with transportation to the place of possible use. Our technique innovation consists in the account of plastic properties of a material defined by the diagramme of plastic current and real contacts between shock absorber components. This method allows defining stress-strain state and shock absorber breaking acceleration at impact of container about rigid support using ANSYS Workbench 16.1. The offered technique is confirmed by the analytical decision of the differential equation of container with shock absorber in elastic area at impact. These two algorithms are illustrated on the actual radial shock absorber made from two rows of cylindrical tubes connected among themselves. These tubes are made from aluminium alloy AMg6. It is illustrated that two layers of tubes have various fastening to each other and rigidity of layers. Hence, compression and destruction will occur in two stages. At first, the external layer of pipes is deformed. After that, internal one is deformed. It is established that strain energy will exceed more than half of kinematic energy of shock-absorber before blow. The curve of shock-absorber braking acceleration is found depending on crumpled area size.
