在机务段和车辆段条件下减震器的工作能力最好是用相当于簧下重量的衰减振荡法来评定。用这种方法评定的精度相当于强制振动法。而相应的试验台要简单和便宜,且有手动起动。在试验台机身1(见图)上装有车辆圆簧2、支架4和与支座3铰接的臂杆5。在臂杆自由端上装有等效的重块10。试验台支架和机身装有垂直安装减震器14用的座15。记录装置有固定在臂杆上的记录笔和位于支架12导轨7内的移动图板6。图板用皮带轮
In the locomotive depot and depot condition, the working ability of the shock absorber is best evaluated by the decay oscillation method equivalent to unsprung weight. The accuracy of this method is equivalent to forced vibration method. The corresponding test bed to be simple and cheap, and have a manual start. A vehicle round spring 2, a bracket 4, and an arm 5 hinged to the support 3 are mounted on the test bench body 1 (see FIG. Equivalent weight 10 is attached to the free end of the boom. The test stand holder and body are provided with a seat 15 for mounting the shock absorber 14 vertically. The recording device has a stylus fixed to the arm and a moving plate 6 located in the guide rail 7 of the holder 12. Plate with a pulley
