摘　　要：在双层集装箱平车的运行和试验中发现重车时车体垂向振动加速度超出相关规范的限值。为此从试验数据分析和刚柔耦合系统动力学仿真计算两个角度对问题进行初步研究,结果表明车载集装箱附加质量引起车体自身的高频弹性振动及垂向弯曲振动模态的改变,进而造成加速度超出规定限值。可通过优化车体结构及相关特性参数等措施来避免或减小加速度超限的问题。The vertical acceleration of heavy container flat car in running and test beyond the limited value provided in the （Railway vehicle-specification for evaluation the dynamic performance and accreditation test 〉. Then, this problem was researched in terms of analysis of test data and simulation of rigid-flexible coupling model. The results show that that the high frequency elastic behavior and change of vertical bending modal result from the additive quality of carbody bring about the exceed limit of vertical acceleration. In a word, we can avert or reduce this adverse problem by way of optimize the structure of carbody and some characteristic parameters.
