Abstract: This paper presents a theoretical and experimental analysis of an anomalous data detection treatment for roller-integrated compaction measurement (RICM) data. Anomalous data, which may be discovered during the collection ...

Abstract: Improving aerodynamic performance with limited dimensions is becoming more important in the design of multirotor aircraft. Complex coupling interactions exist between the structural parameters and aerodynamic performance ...

Abstract: The emergency extension system for nose landing gear (NLG) is vitally important for safe landing in the event of hydraulic source failure. To study the dynamic properties of NLG emergency extension, it is necessary to ...

Abstract: In order to obtain the lunar lander soft landing performance impact caused by the body gravity centerline shift, a seven-degree-of-freedom dynamic model is established based on the inertia force, and a dynamics and kinematics ...

Abstract: Assembly tolerance design for spatial mechanisms is a complex engineering problem that involves a highly nonlinear dimension chain equation and challenges in simplifying the spatial mechanism matrix equation. To address ...

Abstract: To improve the crashworthiness of the landing gear buffer, an oleo-pneumatic buffer combined with an expansion tube is proposed in this paper. A numerical analytical model based on deformation theory was used to acquire ...

Abstract: Controllable lunar landers with magnetorheological fluid (MRF) damper have become a hot topic of research. However, limited research studies have been performed on the damping force analysis of MRF under high-velocity ...
