One of the distinguishing properties of elastomers is their high elasticity. The main characteristics of elastomers present themselves, in particular when comparing them to steel. Below we would like to elaborate on the main properties of elastomers in more detail. Figure 1 shows the main characteristics of elastomers. They are able to combine spring properties as well as damping ability in one component.

Stiffness describes the ability of a body to resist elastic deformation. The transmission of power would not be possible without stiffness. However, there are events which should not be transmitted, such as torque peaks and shock loads. In order for a system to withstand such loads, it is damped. Engineers are confronted with the challenge to tune stiffness and damping in a vibratory system in such a way that reliable operation, essentially free of load peaks, is ensured.   

The robust drill on the robot arm of the Mars Rover Curiosity helps scoop rock dust on Mars – a milestone for researchers. A friction spring made of stainless steel dampens the forces generated during the drilling process and prevents any resonance phenomena.
