Modal Analysis of L Type Compressor Crankshaft

The Finite Element Analysis of the Deflection of the Crankshaft of Rotary Compressor

The deflection of the crankshaft which transfers the power of motor to the pump of the compressor directly affects the vibration, noise and wear problems in the rotary compressor, therefore, with the requirement of higher reliability, it is important to obtain it exactly in compressor design. Various forces that the crankshaft suffers are calculated by theoretical analysis in the operation proc...

Design of Compressor Suspension Systems Using Modal Analysis

A modal analysis procedure is used to model suspended compressors and their excitation forces. The modal method evaluates the dynamic spring forces, modal spring forces, and modal forcing function to determine the effects of a change in suspension configuration on transmitted spring forces. Valuable design insight is gained since the modal parameters explain the behavior of suspension systems d...

Multi-Body Dynamics Analysis of V-Type Diesel Engine Crankshaft

Based on the V-type diesel engine crankshaft system, the paper combined the finite element method (fem) and multi-body dynamics method together, made a virtual simulation analysis. First, by 3d software and finite element software to establish the multi-body dynamic models of the crankshaft, bearing and piston, then simulated the actual engine working condition, and got the data such as cranksh...

Tribology Analysis in Rolling Piston Type Compressor

R & D Laboratories, DAIKIN INDUSTRIES,LTD. Sakai,Osaka,Japan This paper refers to an improvement of the lubrication in a rolling piston type rotary compressor. The lubrication conditions of lubricated surfaces are examined in running compressor and some parameters of them are numerically analyzed. It is elucidated from the investigation that,when unfavorable condition occurs,the metallic contac...
