Effectiveness, safety, customization, profitability – the diverse and complex requirements in drive and damping technology are constantly increasing and changing. How do development engineers approach them? What specific solutions do they create for different industrial and technological sectors? How are pioneering innovations successfully achieved that provide real added value? We discuss this and much more in our The Engineer's Blog.

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

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

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?


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.
