摘　　要：在动态模拟台车试验中,减速度曲线问题是台车试验能否顺利完成的重要条件之一。对于不同的台车试验,所规定的试验曲线都有所不同,为了能够快速有效地满足法规或开发试验的要求,本中主要通过对动态模拟试验台车积累的大量试验数据进行了归纳分析,总结出了影响试验减速度曲线的重要试验因素,建立了试验数据库,寻找出了试验因素和试验曲线的减速度峰值、减速度脉宽等试验要素间的规律,使得试验曲线在一定程度上得到了有效地控制;并结合具体实际试验验证规律的正确性。In dynamic simulation sled test, deceleration curve is one of the important conditions for the successful conclusion of the sled test. For different sled test, test curves are different prescribed. To be able to quickly and efficiently meet regulatory requirements for testing or development. The mainly summarized and analyzed in a large number of experimental data accumulated dynamic simulation sled test,summarized the significant factors affecting the test deceleration curve,established a test database,found out the law of the elements between the experimental factors and test deceleration curve peak deceleration pulse, etc. So that to some extent the experimental curves obtained effective control,and combined with specific practical test to verify the correctness of the law.
