摘要
大功率电源半挂车需承载大容量应急发电设备,普遍存在超重问题,影响行驶安全性。针对大功率电源半挂车底盘减重需求,提出减重方案。通过槽钢正向布置、工字梁开槽贯通、拼接式鹅颈结构等,优化底盘结构。采用有限元分析方法,在扭转工况下对原底盘和减重底盘进行仿真对比。结果表明,减重底盘的质量降低22.5%,安全系数提高至2.226。研究验证了该减重方案在保证结构强度前提下实现轻量化的可行性。
High-power mobile generator semi-trailers,which carry large-capacity emergency power generation equipment,commonly face overweight issues that affect driving safety.This paper proposes a weight reduction scheme addressing the chassis weight reduction requirements of high-power mobile generator semi-trailers.Through technical improvements including forward-oriented channel steel arrangement,through-slotted I-beam design,and spliced gooseneck structure,the optimized chassis structure design was achieved.Using finite element analysis method,comprehensive simulation comparisons were conducted between the original chassis and the weight-reduced chassis under torsional loading conditions.The results demonstrate that the mass of the weight-reduced chassis is decreased by 22.5%,and the safety factor is increased to 2.226.The research findings validate the feasibility of the weight reduction scheme in achieving lightweight design while ensuring structural strength.
