The damping principle of high rise multistorey buildings equipped with suspension-mass pendulums was discussed and their damping performance was investigated.
Based on the principle of compound pendulum,the measurement method and corresponding equipment for the centroidal deviation and the rotary inertia of rocket projectile were described.
According to the measure of trilinear torsion pendulum and mechanical vibration theory, this paper presents the measure of compound trilinear torsion pendulum.
