Damping calculating is key for dynamic calculating model analysis,especially for response analysis.

The design of vane MRF damper which based on conventional vane hydraulic damper is briefly introduced,and the damping moment calculation model is deduced on the basi.

Multi-project adjustable direct integration methods with improved algorithm damping;

The research progress of high damping magnesium alloys and magnesium based composites is briefly introduced in this article, and the influence of strain amplitudes, frequency, temperature, heat treatment and ingredients on the damping property of magnesium alloys is discussed, and the damping mechanisms and damping design of magnesium based composites are analyzed.
