一、前言为了改善和保持舒适度,有必要对许多车辆进行走行时的振动测定。这就需要有自动记录方法,不用人工可在列车运行图的任意时间内进行测定。为此,试制了走行信息发生器(简称发生器),编制了应用记录手册,并在特快电动车的振动测定中得到了肯定。二、走行信息发生器的试制和计测仪器的使用使用图示的计测仪器,可以在8辆或16辆的营业列车上测定车体振动加速度。用设置在驾驶台上的发生器控制,把振动分析所 I. Preface In order to improve and maintain comfort, it is necessary to measure the vibration of many vehicles while walking. This requires an automatic recording method, which can be manually measured at any time during the train operation. To this end, trial production walk information generator (referred to as the generator), the preparation of the application records manual, and in the determination of the vibration of the express electric car has been affirmed. Second, the running information generator trial and use of measuring instruments The use of graphical measuring instruments, can be 8 or 16 commercial vehicles on the measured vibration acceleration. With the generator set on the bridge control, the vibration analysis
