Dynamic rigidity of a beam in a moving contact (English)
0 references
The equivalent dynamic rigidity is studied of the Timoshenko beam resting on an elastoviscous base and interacting with a point object moving uniformly on it. A generic relation for the equivalent rigidity of the beam is obtained and analyzed. The equivalent rigidity is studied as a function of the object velocity. A comparative analysis of equivalent rigidities of the Timoshenko and Bernoulli--Euler beams is performed.
