Experimental investigations of stiffness and damping of rubber springs for resilient mounting of machines

摘要

For a sufficient accuracy at the calculation and at the design of resilient mountings a good representation of dynamic properties of the spring elements is required. The manufacturers of rubber springs declare as a rule static values. They do notinform about the influence of essential factors at the dynamic behaviour as amplitude, frequency, preload and temperature. The aim of experimental investigations is to determine the essential dependences at stiffness and damping of concrete rubber springelements. This is done also in order to enable a qualified comparison of measurement and calculation of a resilient mounting.
