metadata.value: The analysis of previous works devoted to experimental studies of the frequency characteristics
  of the body of a sitting human body subjected to vibration and the construction of its
  mechanical models is conducted. It is noted that in most cases measurements of vibration
  are made on the seat and the head of the person that allows us to build a transmission
  function from the seat to the head. In doing so, the supposed internal structure of the
  human mechanical model remained unconfirmed. Under these conditions, it was emphasized
  that vibration measurements should be performed on all modeled parts of a human body.
  In addition, from an anatomical point of view, the main contribution to the mechanical
  properties of the body of a sitting person is made by the multi-jointed muscles of the spine.
  However, this important fact has not been taken into account yet. In this regard, the task was
  set to study the influence of multi-articular muscles on the frequency properties of the body of
  a sitting person. For this purpose, a number of mechanical models were constructed in which
  multi-jointed muscles were modeled by multi-link viscoelastic connections. In particular, on
  the simplest model with two degrees of freedom it was shown how the imposition of twolink
  connections in addition to a single-link one leads to the appearance of an anti-resonant
  frequency on the upper mass, that is impossible in their absence. A mechanical model with
  an arbitrary number of degrees of freedom with multi-link connections is given, for which
  the formulas of the transfer function and the amplitude-frequency response for the upper
  mass are obtained. In addition, we consider a mechanical model with an arbitrary set of
  multi-link connections. As an example, the results of numerical calculation of the frequency
  response for a mechanical model with eight degrees of freedom in the presence and absence
  of multi-link connections are given.
