Parametric identification of inertial parameters

Abstract: The moments of inertia of solids are usually experimentally determined on irregular axial rotations and the inertia tensor of the body at its point -on six axial rotation, or on non-spherical motions. Frictional forces in bearings of the actuator adversely affect the accuracy of parametric identification. The paper proposes a method of parametric identification of the inertia tensor matrix of a rigid body and the coordinates of its centre of mass at a spherical motion of the particular form. The proposed metho… Show more

“…Usually, during centrifugal casting, this indicator is more than 100 units; accordingly high rotational speed (more than 3000 rpm) is used. High rotational speeds of the unbalanced system necessarily lead to the vibrations in it [13][14][15][16], which can adversely affect the entire installation. Using low rotational speeds will reduce the dynamic loads on the rotor, as well as allow using other types of engines, such as a stepper motor.…”

“…Для решения первой задачи предлагается расширить метод идентификации [3,4,9,10] с целью учета особенностей разгонного этапа, этапа торможения и влияния плоской стенки. Рассмотрим неравномерные вращения тела в жидкости вокруг его фиксированного центра тяжести O на глубокой воде по углу ϕ вокруг вертикальной оси под действием момента, создаваемого двигателем (рис.…”

“…Рассматривается энергетический метод идентификации, развиваемый в работах [1][2][3][4]. В отличие от предыдущих работ здесь рассматриваются управляемые колебания модели судна по углу крена на реверсивно-симметричных участках движения, параметры модели раскачивающего устройства определяются в дополнительном эксперименте по итогам основного.…”
