| Abstract: | The experimental study on static strain and stress of a steel crown and graphite cast iron skirt composite-piston under static load has been carried out. The static strain and stress at key positions under the both conditions of bolts fastening and oil pressure application simulation are analyed. The safety verification of static strength is examined. These provide the practical reference for further improving structure design of such a piston and increasing the reliability of design method. |
