为了对ТЭП80型内燃机车动力性能及其对线路的作用进行评估，进行了速度从160～260km／h的综合动力试验。文中介绍了ТЭП80型内燃机车走行部分的新颖结构和主要特性，叙述了机车试验准备、选择线路试验区段的基本条件和试验方法，提供了机车在160～260km／h速度范围内在直线、道岔和曲线区段上运行试验的结果，并根据运行试验中测得的动力指标（构架力、垂直动力系数等）分析结果，进行了高速运行安全性的评估。
In order to evaluate the dynamic performance of the ТЭП80 diesel locomotive and its effect on the line, a comprehensive dynamic test was carried out with speed from 160 ~ 260km / h. This paper introduces the novel structure and main features of the running part of ТЭП80 diesel locomotive, describes the basic conditions and test methods for locomotive test preparation, selection of the test section of the line, and provides the basic theory and test methods for locomotive running in the range of 160 ~ 260km / h, Curve section of the running test results, and based on the running test measured dynamic indicators (frame force, vertical dynamic coefficient, etc.) analysis of the results of high-speed operational safety assessment.
