In order to solve the problem that the weight of large scale theodolite's casting or steel plate welded structure is too heavy, lightweight design of large scale turntable based on topology optimization of continuum structure is investigated. Topology optimization could have better optimization efficiency because it can provide the optimized distribution of material and gain optimized structure in...
This paper introduces an accurate phase variable model with detailed evaluation of the force ripple for the linear permanent magnet brushless DC motor (LPMBDCM) drive system analysis. The mover position dependent variables of the physical model are obtained from finite element (FE) solutions by the cubic spline interpolation. Considering the effect of the snubber circuits in the power electronic devices,...
