Simple chain dynamic model forming conditions Ratko Šelmić Mechanical models with concentrated reduced masses
joined by flexible components of various rigidity are often used in dynamic
calculations of machines and
mechanisms (cranes, bulldozers, machine tools, lift mechanisms, mining
winches, drilling sets). Generally speaking, it is possible to reduce
such systems to those with less degrees of freedom. This causes errors in the
oscillation frequency. The cause and degree
of the error is shown through numerous examples. Ključne reči: mechanical model, mass, rigidity, frequency, error. |
