Abstract

This study focuses on upgrading a scissor lift platform to address issues of displacement and excess weight. The objective of this study is to reduce metal consumption and increase structural rigidity by utilizing optimized perforation with flanges. The methodology included ANSYS computer modeling and field experiments with St45 steel test specimens loaded up to 200 kg. Deformations were measured using high-precision sensors. Key results: the optimized perforated platform, under a 200 kg load, demonstrated deflection 2.46 times lower than its solid counterpart, with an 8% weight reduction. The complex specific stiffness criterion increased by 2.66 times. A dependence of up to 25% on the diameter and pitch of the holes was established. The scientific value of the study lies in the identified pattern of combined mass minimization and stiffness maximization in bending elements through rational perforation. Practical significance: the proposed methodology enables the generation of effective design solutions to reduce manufacturing costs and improve the reliability of car lifts.
