In this paper,a new simplified mass-spring system is introduced. By using the mass-spring system,the influence of dynamic performance and construction parameters of a bridge crane are analysized,and dynamic parameters of a bridge crane are optimized.

• 用改进后的质量弹簧简化系统,分析了桥式起重机主要动态性能及结构参数的影响,并对桥式起重机动态指标进行了优化设计。
