Momentum exchange impact dampers (MEIDs) were proposed to control the shock responses of mechanical structures. They were applied to reduce floor shock vibrations and control lunar/planetary exploration spacecraft landings. MEIDs are required to control an object’s velocity and displacement, especially for applications involving spacecraft landing. Previous studies verified numerous MEID performances through various types of simulations and experiments. However, previous studies discussing the optimal design methodology for MEIDs are limited. This study explicitly derived the optimal design parameters of MEIDs, which control the controlled object’s displacement and velocity to zero in one-dimensional motion. In addition, the study derived sub-optimal design parameters to control the controlled object’s velocity within a reasonable approximation to derive a practical design methodology for MEIDs. The derived sub-optimal design methodology could also be applied to MEIDs in two-dimensional motion. Furthermore, simulations conducted in the study verified the performances of MEIDs with optimal/sub-optimal design parameters.

Cell Window

Building integrated photovoltaics (BIPV) are an important application of future solar energy development. The incorporation of solar cells into windows must not only maintain indoor natural lighting but also generate electrical power at the same time. In our continuing effort to improve the design of diffusion solar window, a more fundamental and efficient three-layer structure—glass/EVA with TiO2nanoparticles embedded/glass—was proposed. In this work, a well-established ASAP ray-tracing model for a diffusive solar cell window was implemented to validate the outperformance of three-layer structure over primitive five-layer structure. Optical simulations were also implemented to perform its primary design for the determination of the optimal design parameters, such as the glass thickness, the EVA thickness, and the weight concentration of TiO2nanoparticles. Based on the simulation results, an optimal design for a three-layer diffusive solar cell window prototype was proposed. And the influence of both EVA thickness and glass thickness on the power edge-exitance (solar cell power generation efficiency) of a DSCW was thoroughly investigated.

Contemporary industrial production widely uses induction heating prior to the plastic deformation and heat treatment operations due to the benefits it provides in comparison with other types of heating technologies. In order to increase the efficiency of induction heating units and develop their operation mode, the research should be directed towards new design solutions in optimizing constructive parameters of inductors and control algorithms of heating processes. The main goal of the research is developing the best inductor design, which provides maximum temperature uniformity in the surface layer of the billet at the end of heating time. There has been formulated the problem of the inductor unit optimal design with respect to steel cylindrical billets, which can be solved by using the alternance method of parametric optimization of the systems with distributed parameters. Design parameters of the induction heating installation that include the geometry features and the current of power supply are considered as optimized parameters. Software package FLUX was used for developing 2D numerical model of interrelated magnetic and temperature fields in the process of induction heating to describe the system ‘induction heater - billet’. The results of numeric solution of the problem of optimal design have been analyzed.
