ANALIZA UNEI CAME CIRCULARE EXCENTRICE (Rezumat) Camele circulare excentrice sunt mecanisme componente ale multor dispozitive mecanice. În anumite situaţii tachetul acestor came se poate bloca în ghidajul acestuia dacă dimensionarea nu este corectă. Lucrarea analizează modul în care se poate evita blocarea tachetului printr-o alegere corectă a lungimii ghidajului bazată pe rezolvarea unor sisteme de ecuaţii de echilibru. Rezolvarea problemelor calculatorii este făcută cu ajutorul programului Mathcad.

FIZICĂ CORRECTION METHODS OF THE BIOMECHANICAL MODEL IN THE CASE OF FOREARM MOVEMENT BY PETRONELA PARASCHIV ∗ “Gh. Asachi ” Technical University of Iaşi, Department of Physical Education and Sports Received: May 10, 2012 Accepted for publication: June 15, 2012 Abstract. The simplifications that are made in the case of biomechanical models lead to the necessity of `correcting` the models achieved through permanent comparison with the experimental registered values. There are discussed three correction methods of biomechanical model in order to approach the experimental model to the theoretical one. For the situation in which there is the need to compare two curves, an experimental one, given by the relative values and a theoretical one, given by absolute values, the interpolation can allow finding a convenient function of interpolation, the same one for both curves to be compared, in which the coefficients of the mathematical function differ from one curve to the other. The interpolation function must satisfy the condition that it represents the best approximation for any other two curves, experimental and theoretical, that express the variation of the same physical phenomenon. Key words: biomechanical model. 1. Introduction At the time being there are no well defined mathematic methods of correction of an analytical model, but depending on a situation or another there can be applied diverse “local solution”.
