Abstract
In the present paper authors wish to propose a method for the modeling and formulation to improve the design process of piping lines in the air conditioning unit. The essential part of the proposed method is to combine three identification principles : (1) the kinematical and kinetic analysis of compressor for obtaining the exciting forces and torque transmitted to piping lines; (2) the derivation method of physical matrices of piping lines with the finite elements method; (3) the experimental identification method of physical matrices of the compressor and accessories on resilient supporting elements using modal parameters obtained by modal testing.
The proposed method simplifies a procedure for formulation process of the compressor-piping coupled system and estimates accurately dynamic responses of piping lines. Validity of the proposed method is corroborated with experimental results.
