They have achieved significant results in the theoretical study of low-speed collision dynamics, friction dynamics, dynamics of incomplete systems, particle rheology, and aerospace engineering applications. The gap model they proposed is known as the \u201cLiu-Model,\u201d and their method for solving multipoint collision dynamics is referred to as the \u201cLZB\u201d method. The team systematically resolved the \u201cPainlev\u00e9 Paradox\u201d in classical rigid body dynamics. They proposed a viscous mechanism for rolling friction resistance. Through both experimental and theoretical approaches, they addressed the challenging Painlev\u00e9 problem in rigid body dynamics. They introduced a variable-structure dynamics analysis framework and associated algorithms that account for friction effects. They formulated Archimedes&#8217; principle for granular flows and established a geometric mechanics analysis framework for the dynamics of incompletely constrained systems.<\/p>\n\n\n\n<p>In recent years, Professor Liu Caishan&#8217;s multibody dynamics research team has made a series of significant contributions to major aerospace projects, including fault-to-zero analysis for the Long March 5 rocket and lunar soil drilling and sampling for the Chang&#8217;e 5 mission.
