DYNAMICS EQUATIONS FOR A CAR INSPECTION MOBILE STRUCTURE
Journal Title: ACTA TECHNICA NAPOCENSIS, Series: Applied Mathematics, Mechanics, and Engineering - Year 2016, Vol 59, Issue 0
Abstract
The paper is devoted to establishing the dynamics equations, by an analysis of kinematic and dynamic behavior, for a mobile robot, called RmITA. Based on geometric modeling of the structure, there will be determined the kinematic constraints that affect the structure. Also, the mathematical model used to determine the dynamics equations, will be based on new concepts in advanced mechanics, based on important scientific researches of the main author, concerning the acceleration energy. In keeping the fact that the mathematical models of the mobile platforms are different besides the other robots types, due to no holonomic constraints, the dynamic control functions, will be established according to restrictions for motion.
INFLUENCE OF WING TIP SHAPE ON LONGITUDINAL STABILITY OF GLIDER AIRPLANE MODEL
There were analyzed four different wing tip shapes. The coefficient of restoration, CR, is given by the ratio of the largest half wing to the smaller half wing in horizontal projection. Flight is stable for CR = 1.00. Th...
