On the number of mechanical configurations for nonlinear stiffness systems designed based on a linear spring with a nonlinear boundary
Qiangqiang Li, Qingjie Cao
In this paper, we present a novel integrated method for designing nonlinear stiffness systems based on a general spring-boundary model (GSBM) to study the number of mechanical conf…

A general nonlinear mechanical model based on special-shaped mechanism
Qiangqiang Li, Qingjie Cao
Nonlinear systems exist widely in nature, however, how to construct systems with accurate expected non-linearity artificially is still a problem, which greatly limits their experim…

Lyapunov-based Low-thrust Optimal Orbit Transfer: An approach in Cartesian coordinates
Hantian Zhang, Dong Eui Chang, Qingjie Cao
This paper presents a simple approach to low-thrust optimal-fuel and optimal-time transfer problems between two elliptic orbits using the Cartesian coordinates system. In this case…
