The traditional analogy method based on experience is insufficient for large and complex ram; it is difficult to have a reasonable distribution of materials, so the potential of the materials is unable to be fully exerted.
According to the strength, stiffness and precision requirements of the ram structure and ram materials’ mechanical properties, the state variables of the ram were confirmed.
