What are the ways to improve the fatigue life of parts?

(1) Reduce stress concentration in design, avoid sharp-angle connection at the transition point;


(2) Reduce the surface roughness of parts;


(3) Strengthen the surface, causing residual compressive stress on the surface of the part, offsetting part of the tensile stress, reducing the peak value of the actual tensile stress on the surface of the part, thereby improving the fatigue strength of the part.
