Common Fracture Positions of Leaf Springs and Root Causes
Fracture at the middle section (clamped area by U-bolts, most frequent failure) this region bears the maximum bending stress under load. Possible causes include unreasonable parabolic profile leading to stress peaks, internal material inclusions, improper hardness after heat treatment, and insuff...Read more -
Design Optimization of Leaf Springs for Overload Working Conditions
Leaf springs for commercial vehicles are prone to fatigue deformation and fracture under long-term overload operation. Excessive load drives the spring material to work close to its yield strength and aggravates alternating stress concentration. While structural and technological optimization ca...Read more -
