Sprung translation mechanisms driven by electromagnetic force actuators are often used to produce controllable motions. This paper is concerned with one family of such devices incorporating linear spring mechanisms suitable for short-range, high-precision applications. In these, a permanent magnet is attached to the movable translating stage which is, in turn, surrounded by a solenoid coil attached to a fixed datum. Design considerations are discussed, principally an optimum dimensional design for a uniformly wound circular cylindrical coil. Design models are verified by the construction of a simple device in steel and aluminium which demonstrates an open-loop positional accuracy of better than 0.5 per cent over a displacement range of 100 nm to 50 μm.

Abstract In this paper, a non-traditional variant nonlinear energy sink (NES) is developed for simultaneous vibration suppression and energy harvesting in a broad frequency band. The non-traditional variant NES consists of a cantilever beam attached by a pair of magnets at its free end, a pair of the so-called continuous-contact blocks, and a pair of coils. The beam is placed between the continuous-contact blocks. The constraint of the continuous-contact blocks forces the beam to deflect nonlinearly. Each of the magnet-coil pairs forms an electromagnetic energy harvester. Different from a traditional way that attaches the coils to the primary mass, the developed setup has the coils fixed to the base. First, the developed apparatus is described. Subsequently, the system modeling and parameter identification are addressed. The performance of the apparatus under transient responses is examined by using computer simulation. The results show that the proposed apparatus behaves similarly as the NES with the following features: 1:1 resonance, targeted energy transfer, initial energy dependence, etc.
