Terminal load distribution and pipe network structure are the key factors that affect the energy-saving potential of central air-conditioning chilled water systems, nonlinear thermodynamic performance of an air-conditioning system with large inertia will mainly exert influence on the stability...

As existence of machining and installation error, meshing gear pairs have angle error of intersecting shaft, resulting in eccentric load and impact, which seriously weakens gear transmission performance. First, based-on gear meshing principle, this paper equates the angle error with tooth lead...

Sm-Co permanent magnets are usually very brittle which makes them vulnerable to even mild impacts. Recently, it is reported by simulation and confirmed by experiment that SmCo 5 can be plastically deformed via amorphous shear bands activated by external stress Since most Sm-Co magnets mainly...
