Mechanical oscillatory systems with progressive motion. Possible forms of link connections.
Engineering Education # 12, December 2012 DOI: 10.7463/1212.0486791 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.
Characteristic features of registration of ties superposition effects for system with couplings
Engineering Education # 09, September 2011 General questions of mathematical modeling of mechanical oscillation systems with couplings are considered. The article covers an extension of a well known theorem about superposition effects.
Between coordinates ties in theory of vibroprotection
Engineering Education # 04, April 2011 Methodical bases for building of transport mathematical models vibroprotection systems are suggested. Considered systems have lever mechanisms and additional ties, which can be realized through using of elementary typical links of widen collection.
Dynamical absorber. Influence of position
Engineering Education # 03, March 2011 Questions of influence of position of dynamical absorber on properties of object with two degrees of freedom are considered. Building of effective system of defense from vibration and getting of additional regimes of dynamical absorbtion with coupling are offered.
