Influence of adhesive overflow phenomenon on module-free power battery pack mode
摘要
Abstract
To investigate the impact of end plate adhesive overflow on the modal behavior of module-free power battery packs,this study established a research framework encompassing theoretical analysis,structural design,and system verification.The feasibility of end plate adhesive overflow was first analyzed,with three distinct structural designs proposed for adhesive overflow space.Compara-tive evaluations demonstrate that the increased chamfer height on end plates simultaneously en-hances adhesive overflow height and uniformity.Subsequently,prototype-level and system-level simu-lation analyses coupled with experimental validations are conducted based on optimized end plate ad-hesive overflow designs.Comparative modal analysis reveals that the adhesive overflow design achieves approximately 12%higher first-order frequency than conventional configurations,signifi-cantly improving system stiffness and demonstrating substantial engineering value.Additionally,the adhesive overflow mechanism redistributes gravitational forces from battery cell modules on liquid-cooling plates through adhesive dispersion between end plates and cross beams,thereby reducing di-rect stress on liquid-cooling plates and minimizing vibration-induced failure risks.关键词
