Vibration is mostly unwanted when it creates uncomfortable noise, results in danger, and wastes energy. As a result, vibration control has always been of interest to researchers. Semi-active control not only requires less external energy acting as control energy and performs more stable than active control, but also works over a larger frequency range and performs more flexible than passive control. So, semi-active control systems are applied in many engineering areas. A switched stiffness system, working as a semi-active control system, was realized by many stiffness switching laws and explored by lots of mechanical structures in the last decades. But, in most of the present switching stiffness systems, during a vibration reduction process there still exist unavoidable time instants, where elastic elements release potential energy stored by themselves, and drive the mass to move again. This is the intrinsic property of an elastic element, but this results in an oscillating system response to some extent. In order to further reduce this adverse effect of elastic elements on vibration control, this special issue documents how elastic elements affect system response and then introduces a new type of vibration control system. The new system does not dissipate energy into heat, but stores the kinetic energy as potential energy in elastic elements. Original research papers are solicited in any aspect of Semi-active switching stiffness vibration control based on energy harvesting.
