Influence of the dynamic propertiesof rubber spring elements on vibrationbehaviour of concrete b

Concrete block making machines are characterised by their product producing flexibility, different operating modes and highly complex vibration processes. They are used for producing concrete products (Fig. 1), as everybody knows. These concrete products stand out due to the type of concrete quantities to be processed, their geometry, the type of surface and hardened concrete properties. The resulting flexibility requirements for such types of production machines are very high. Therefore concrete block making machines have not only very complex machine static systems but also dynamic ones (Fig. 2).
