摘　　要：为最大限度地提高汽车的安全性和环保性,首先对前期设计的泡沫铝填充结构车门防撞梁的吸能量、比吸能率进行理论分析并建立了相应的数学模型;然后应用MATLAB软件对其进行结构优化设计得出最优结构;最后将优化前后的泡沫铝填充结构车门防撞梁的各项指标进行对比分析。结果表明,优化后的泡沫铝填充结构车门防撞梁在提高汽车安全性及环保性方面有明显提高。In order to improve the safety and environmental protection property of the car, we first analyzed the theory about energy absorption and the ratio of energy absorption of anti-collision beam. We had studied and designed before and es- tablished its corresponding mathematical model. Then we optimized its structure and got the optimal structure by MATLAB soft- ware. Finally, the comparison of some index were performed between original and optimal structure of the anti-collision beam. The results indicated that the last one had a better safety and environment protection property.
