摘　　要：以质量最轻为目标函数,在满足强度和刚度的条件下,采用优化设计方法对轨道衡称梁进行了优化设计。在模型建立中考虑了钢轨对称梁的影响。结果显示,强度在设计中与刚度具有同等重要地位。Aiming at the minimum mass, the beam of rail weight bridge is designed adopting the optimal approaches under the conditions of strength and stiffness. The influence of steel rail on beam ofrail werght bridge is considered in establishing models. The results indicate that strength is as important as stiffness in design.

关 键 词：轨道衡 称梁 强度 刚度 优化设计
