This study discusses the developement of hydraulic rotary actuator design technology for industrial machinery and earthmoving equipment. The lubrication and wear analysis of sliding components of the machinery are very important parameters to strength the design technique. The analysis and wear test are performed for the selected materials of the above mentioned coupled sliding members. The can be used to select the better combinations of sliding components.

This paper aims at calculating optimum design dimensions to minimize the weight satisfied strain and stress intensity of the frame while loading maximum weight into a mechanical press in the static condition. Analysis of the frame was carried out by using the FEM, then the optimum condition was obtained by using these data. As modeling in the finite element analysis has great impact on the reliablity of analysis results, the analyzed object was selected a 150-ton mechanical press of J Company, the part little affected to structural rigidity was simplified, the load condition was considered in the only maximum load, the boundary condition was used by giving symmetric displacement due to symmetric boundary condition, the finite element was applied a linear membrane element. An intermediate processor program applied the normal ANSYS to analyze finite elements was developed, and the design sensitivity was calculated. This program was applied to the optimum design.
