Application of Multi-objective Topology Optimization Algorithm in Heat Transfer Optimization of Hydraulic Brake
为有效提升液压制动器的传热性能,基于多目标优化算法对风冷盘的厚度、风槽高度、肋片倾角和肋片数量等设计变量进行拓扑优化,实现制动盘温度峰值和质量的同步降低.采用PDE方程建立风冷盘传热模型,以负热流为边界条件,求解出恒压匀速制动工况下的二维瞬态温度场.基于ANSYS Workbech建立风冷盘的三维参数化传热模型,利用台架试验法验证温度场仿真结果.采用中心组合设计法得出设计变量与优化目标的离散样本,通过多元二次回归模型构建代理模型并进行误差校核.构…查看全部>>
