Stress Analysis of Suspension Springs and Discharge Loop Under Impact Conditions for Hermetic Compressors Using FEM
نویسندگان
چکیده
The transport worthiness of suspension springs and discharge lo0p in hermetic compressors under impact conditions has been analysed by analytical and computational simulation. The equations represent static behaviour to consider the maximum stresses arising from the impact loads. The problem is divided into two parts. The discharge loop is analysed by linear one-dimensional finite elements in 3-D space. Fixed end. boundary conditions are applied at the Shell end of the loop and Load conditions are applied at the Discharge Muffler end. The loads are transmitted by the springs to the pump and motor assembly and evaluated analytically. The discharge loop is considered as an additional spring and the spring constant is determined using the FEM. Using the analytical formulae and FEM the failure loads and stresses are calculated for two types of loop geometri-es and two types of mounting systems. However the method can be extended to other combinations of loop geometry and springs.
