哈尔滨减速顶调速系统研究中心受上海铁路局委托于1983年9月15日——9月17日在哈中心三棵树试验线对上海局工业公司所产减速顶进行了测试。因哈中心测试人员需于9月19日赴杭参加铁道部对艮山门的鉴定测试,所以,这次测试的时间很短,测试数据少,加之天气不佳,尤其阻力功的测试是在小雨中进行。故此,所得数据不够理想,待有机会可进一步测试。 Harbin Deceleration Speed ​​Control System Research Center commissioned by the Shanghai Railway Bureau in September 15, 1983 - September 17, 1983 at the center of three trees test line produced by Shanghai Bureau Industrial Corporation deceleration roof was tested. Inha center testers need to be in Hangzhou on September 19 to participate in the ministry of railways to the Genshan door identification test, so the test time is very short, less test data, combined with poor weather, especially the resistance test is in the light rain In. As a result, the data obtained are not satisfactory and will be subject to further testing.
