This paper deals with finding Lagrangians for damped, linear multi-degree-of-freedom systems. New results for such systems are obtained using extensions of the results for single and two degree-of-freedom systems. The solution to the inverse problem for an n-degree-of-freedom linear gyroscopic system is obtained as a special case. Multidegree-of-freedom systems that commonly arise in linear vib...

A dumbbell-shaped rigid body can be used to represent certain large spacecraft or asteroids with bimodal mass distributions. Such a dumbbell body is modeled as two identical mass particles connected by a rigid, massless link. Equations of motion for the five degrees of freedom of the dumbbell body in a central gravitational field are obtained. The equations of motion characterize three orbit de...

Vertical dynamics modeling and simulation of a six-wheel unmanned military vehicle (MULE) studied in this paper. The Common Mobility Platform (CMP) chassis provided mobility, built around an advanced propulsion and articulated suspension system gave the vehicle ability to negotiate complex terrain, obstacles, and gaps that a dismounted squad would encounter. Aiming at modeling of vehicle vertic...

in this paper, multi-objective uniform-diversity genetic algorithm (muga) with a diversity preserving mechanism called the ε-elimination algorithm is used for pareto optimization of 5-degree of freedom vehicle vibration model considering the five conflicting functions simultaneously. the important conflicting objective functions that have been considered in this work are, namely, vertical accel...

A = assembly operator B = set of degree-of-freedom indices corresponding to boundary nodes Ccp = set of degree-of-freedom indices corresponding the contact pairs D = set of degree-of-freedom indices corresponding to deleted degrees of freedom F̂ = virtual impulse associated with the amount of penetration f = contact force vector G = set of degrees of freedom corresponding to all generalized inte...

Open Data repositories store a variety of information from country governments and private sectors that can be used to conduct research, development and analysis. The volume of data made publicly available supporting the Freedom of Information Act is increasing exponentially as new data is being published by government and private sectors upon users request. A concern with the releasing of gove...
