Description:
It is difficult to obtain boundary conditioners for air conditioner piping system by FE model. An estimating rotational degree of freedoms (RDOFs) component mode synthesis (CMS) method is presented and used to determine the boundary conditions. This paper presents the method to determine the boundary conditions of the piping system from experimental data. A piping system of the air conditioner is carried out as an example using MSC. Nastran, and the comparisons between the results and the experimental ones show the achievements.
