Why Every Component of a Cement Mill Counts in the Production Process

By Björn Schumacher on Jan 18, 2017

Operators of cement plants worldwide face the challenge to create their systems more efficient and reliable. Even though the production and consumption of this material is quite stable in Europe, there is a continuously growing demand in Africa, North America and Asia. For this reason, production needs to be optimized and therefore all components which are part of the drive to guarantee constant operation, minimal downtimes and low maintenance costs.

Fun Facts: Resonance or if system vibrations build up

By Sophie Keil on Nov 23, 2016

When thinking of resonance and race tracks the most obvious link appears to be the roaring of engines. But, it actually covers a much broader scope, which has been exhibited by Renault’s clever engineers at Formula 1.

Reciprocating Engines in Combined Heat and Power Units: Is Higher Power without Loss of Energy Efficiency Possible?

By Thomas Marterer on Aug 03, 2016

The combined heat and power technology (CHP), in particular co-generation units, have long been a part of the industrial energy transition. However, the large potential of combined heat and power units is still underutilized. The reason for this, among others, is because of the properties of the installed drive technology: for instance, the non-uniform torque of reciprocating engines. New components promise more power with consistently good energy efficiency.

Stiffness and Damping: This is what Engineers have to Consider when Tuning a Coupling

By Simon Graf on Jul 20, 2016

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.

Frequency, Amplitude, Vibrations: How is Resonance Created?

By Norbert Telaar on Jul 12, 2016

Every vibratory system consists of an exciter and a mass with a force-transmitting medium in-between. Resonance is caused if this system is periodically excited with its natural frequency. In the field of mechanical engineering, resonance is an undesired phenomenon.

Sophisticated Technology in the Mars Rover Curiosity: Mission Damping Accomplished

By Lars Jahnel on Jul 04, 2016

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.
