Sensitivity analysis for a type of statically stable sailcrafts
Two types of sensitivities are proposed for statically stable sailcrafts. One type is the sensitivities of solar-radiation-pressure force with respect to position of the center of mass, and the other type is t...

The experimental study on the contact process of passive walking
The passive dynamic walking is a new concept of biped walking. Researchers have been working on this area with both theoretical analysis and experimental analysis ever since McGeer. This paper presents our com...

A method for classifying orbits near asteroids
A method for classifying orbits near asteroids under a polyhedral gravitational field is presented, and may serve as a valuable reference for spacecraft orbit design for asteroid exploration. The orbital dynam...

A survey on orbital dynamics and navigation of asteroid missions
Asteroid exploration is currently one of the most concerned topics among international space agencies. Orbital dynamics and navigation are obviously crucial for asteroid exploration. This paper aims to give a ...

Time-optimal rendezvous transfer trajectory for restricted cone-angle range solar sails
The advantage of solar sails in deep space exploration is that no fuel consumption is required. The heliocentric distance is one factor influencing the solar radiation pressure force exerted on solar sails. In...

Low-thrust trajectory optimization in a full ephemeris model
The low-thrust trajectory optimization with complicated constraints must be considered in practical engineering. In most literature, this problem is simplified into a two-body model in which the spacecraft is ...

Non-intrusive hybrid interval method for uncertain nonlinear systems using derivative information
This paper proposes a new non-intrusive hybrid interval method using derivative information for the dynamic response analysis of nonlinear systems with uncertain-but-bounded parameters and/or initial condition...
