Included is the stability analysis of six DOFrailway car model.

The multi-degree matrix,catastrophe theory of functional and by them methods of two kinds of the judgement of dynamic stability of complex nonlinear system,particularly nonlinear nonstationary system are established.

Based on a hydrofolic small waterline area ship(HYSWAS) scheme with fixed hydrofoils, this paper researched the resistance, static stability, dynamic stability of HYSWAS by theoretical methods.

Then we study its dynamic stability with the ZMP(zero moment point) method,and propose a method for caculating the stability margin of the bionic kangaroo robot.

Influence of predeformation on the motion stability of rotor supported by multi-layered steel plate;

Research on Motion Stability of Driver-Vehicle with 4WS Closed-Loop System;

Bifurcation analysis of motion stability for high-speed underwater vehicle

Because of the effects of environmental load in deep water,the physical characters of the mooring line material and the configuration,the analysis of the mooring systems involves nonlinearity due to fluid-solid coupling,the nonlinear hydrodynamic forces and the stability of motions.

It deals with the new principles,inverse problems of system dynamics,many integral methods,as well as the stability of motion of systems et al.

Based on the mechanized mathematics and WU Wen_tsun elimination method, using oil film forces of short bearing model and Muszynska s dynamic model, the dynamical behavior of rotor_bearing system and its stability of motion are investigated.
