Manifold block optimization method by utilizing evolution algorithm

In this paper by utilizing evolution algorithm we proposed an optimization method for manifold block design by using visual basic 6.0 programs. In our designed visual basic 6.0 programs the geometric parameters of hydraulic elements are putted into special designed drawing interface procedure, so the manifold block drawing of hydraulic system can be automatically produced by our designed procedure. At finally, the numerical results by the designed procedure implies that the computational efficiency is greatly improved and the computational time of designing is largely shortened.
