The authors propose a technology for creating mathematical models of mechanical oscillatory systems with a chain structure and several degrees of freedom. Various descriptions of movement in different coordinates are considered. Some coordinates characterize relative motion. Nulling of such coordinates results in combining corresponding mass-inertia elements; hence, the system on the whole reduces the number of degrees of freedom by one. Generalization allowing to set several coordinates equal to zero simultaneously is also considered. Some examples are provided.
