我国交通行业唯一的国家重点实验室——牵引动力实验室于1995年11月2日在西南交通大学通过国家级验收。这标志着我国在机车车辆基础理论研究与大型试验技术方面已跨入国际先进行列。 牵引动力实验室于1989年经国家计委正式批准为国家重点实验室建设项目,是全国投资规模最大的国家重点实验室之一。其主要特点是建有一个滚动、振动相结合的整车模拟实验台。机车车辆可以在台上模拟运行中的滚动与振动,可进行速度为400km/h以内的运行试验。这种试验台,目前世界上只有2台,另一台在德国。实验室以轮轨相互作用的研究为基础,以铁路扩能、提高服务质量和保证安全为目标,着重研究铁路高速技术、重载技术、新型机车车辆和牵引自 China’s transport industry only State Key Laboratory - traction power laboratory in November 2, 1995 at the Southwest Jiaotong University State-level acceptance. This indicates that our country has stepped into the international advanced ranks in the basic theory research and large-scale test technology of rolling stock. Traction power laboratory in 1989 by the State Planning Commission formally approved the construction of the State Key Laboratory projects, is the largest national investment in one of the state key laboratories. Its main feature is to build a rolling, vibration combination of vehicle simulation test bed. Rolling stock can simulate running rolling and vibration on the stage, can run the test within the speed of 400km / h. This test bed, currently only two in the world, the other in Germany. Based on the research on the wheel-rail interaction, the laboratory aims at expanding the railway capacity, improving the service quality and ensuring the safety. It focuses on the research and application of high-speed railway technology, heavy-duty technology, new locomotive and traction
