CH Series Upper Frame Structure Optimization:
Strengthening the Arm Structure – Principle Optimization
Enhancement 1:
The upper arm is a critical load-bearing part of the entire upper frame. FEA (Finite Element Analysis) revealed that the arm structure is a stress concentration point for the entire upper frame. By increasing its resistance strength, the service life of the upper frame can be directly extended.
Strengthen the area of stress concentration
Enhancement 2:
Structural optimization was performed on the reinforcement between the upper flange and the wall to ensure that the axial force generated during crushing is better transmitted from the crossbeam to the upper frame. This minimizes stress concentration and enables the frame to handle more complex working conditions.
Strengthen areas of weakness
Enhancement 3:
SISUPER uses high-grade alloy cast steel, and after casting, applies a heat treatment process of normalizing, tempering, and quenching followed by natural aging. This process forms a large amount of austenitic structure in the microstructure, significantly improving the tensile and yield strength of the base material. The tensile strength reaches 700-850 MPa (yield strength of 400 MPa), improving product stability.
Strengthen the joint and the bearing place
