摘要
首先介绍了基本蚂蚁算法原理和改进的蚂蚁算法,即最大-最小蚂蚁算法,根据传热学原理用微元体热平衡法建立了电子系统热分析求解温度场的数学模型,并采用高斯-赛德尔迭代法求解热平衡方程组,通过仿真实验证明用蚂蚁算法来优化电子元件的布局能够显著降低最大温度值,并提高了系统的可靠性。
An improved ant colony system （ACS） Max-Min Ant System＇（MMAS） is introduced and a mathematical model for evaluating the components＇ temperature in a board of electronic devices is also given. The model was given using the thermal equation of microelement units. Gauss-Seidel iterative technique was employed to solve the linear equations set. Through an example, the placement of electronic components or devices is optimized with the MMAS. The simulation results show the temperature stress was reduced and the reliability was improved greatly. In addition, the steady temperature field of the components in PCB was also analyzed with the thermal analysis software Flotherm, the results show the model and algorithm for optimizing the components layout were effectual.
