Dynamic optimization for the main drive system of a reciprocating compressor considering joiint friction based on ADAMS

The dynamic optimization of a main drive system in a W-type compressor with friction of joints are studied by ADAMS , a special software for dynamical simulation. The dynamic response of the crankshaft journal center of the two rolling bearings are obtained on rated operating condition. On this basis,the mathematical model for dynamic optimization is presented,its objective function is weighted sum of the amplitude of the crankshaft journal center in the two bearings, and the design variable are the angle of cylinder lines and the rotation speed of crankshaft. The parametric simulating model is construc- ted in ADAMS to search for the optimum solution. The relation between the design variable and objec- tive value is disclosed through optimization,which is a function module in the design evaluation tools of ADAMS. Numerical results are available for the dynamic design of piston compressor.
