摘要:

提出一种联合IHHO算法的优化方法,对桁架式清雪车车架进行轻量化研究。首先,构建了车架的有限元仿真模型,在多种工况下对其强度、刚度、模态进行定量分析,得其强度性能、刚度性能及固有频率。其次,利用响应面法以最大变形量和最大应力为响应值,优化车架各梁截面尺寸,得到3组最优解。在此基础上,对HHO算法进行改进,提出IHHO算法,采用IHHO算法验证最优解的有效性。优化结果表明,车架整体质量减轻33.6%,最大变形量减小6.33%,最大应力增加3.01%,1阶模态频率降低19.48%,有效避开了共振范围。本研究为桁架式车架的轻量化设计提供了一种高效、可行的优化策略,该方法在模型构建和获取准确估算结果方面具有显著优势,为相关领域的工程应用提供理论参考。

Abstract:

An optimization method incorporating the Improved Harris Hawks Optimization (IHHO) algorithm is proposed for the lightweight research of a truss-type snowplow frame. Firstly, a finite element simulation model of the frame is constructed, and its strength, stiffness, and modal characteristics are quantitatively analyzed under various working conditions to determine its strength performance, stiffness performance, and natural frequencies. Subsequently, the Response Surface Methodology is employed, using maximum deformation and maximum stress as response variables, to optimize the cross-sectional dimensions of the frame beams, yielding three sets of optimal solutions. On this foundation, the IHHO algorithm is proposed by improving the HHO algorithm, and the effectiveness of the optimal solutions is verified using the IHHO algorithm. The optimization results show that the overall mass of the frame is reduced by 33.6%, with the maximum deformation decreased by 6.33%, the maximum stress increased by 3.01%, and the first-order modal frequency decreased by 19.48%, effectively avoiding the resonance range. This study provides an efficient and feasible optimization strategy for the lightweight design of truss-type frames. The method demonstrates significant advantages in model construction and obtaining accurate estimation results, offering theoretical references for engineering application in related fields.
