This study investigates the effects of a vibration force field on mixing and structural properties polylactic acid (PLA), polybutylene succinate (PBS), ethylene-glycidyl methacrylate terpolymer (EGMA) blends. A balanced triple-screw dynamic extrusion process was utilized to prepare PLA/PBS/EGMA composites under various parameters, specifically amplitude frequency. The results indicate that introduction significantly enhances dispersion blend, leading improved mechanical properties, thermal stability, crystallization behavior. When frequency 6 Hz 1.0 mm, impact strength increased from steady-state value 70.86 KJ/m2 88.21 KJ/m2. 0.4 mm 10 Hz, reached 81.86 orthogonal experimental design entropy method analysis revealed play dominant role in optimizing performance, whereas processing temperature rotor speed exhibit minimal impact. Scanning electron microscopy (SEM) confirmed reduces phase separation, promoting finer more homogeneous PBS EGMA within PLA matrix. Additionally, TGA DTG curves suggest when are lower than specific thresholds, stability blend deteriorates. In contrast, they exceed those improves. For instance, with an initial degradation (T5) climbs 328.6 °C 333.7 °C. At T5 reaches 333.1 These findings provide theoretical support for application vibration-assisted development high-performance biodegradable polymer
