一、关于钢绳推压挖掘机的缓冲美国B—E公司在挖掘机缓冲方面进行了大量的研究和探索,一方面进行现场测定,另一方面利用电子计算机进行模拟计算,采用两种方法测定的结果相差不到3％,如图1和图2所示。试验结论认为,可以利用电子计算机进行模拟现场情况。他们主要采取下面几种缓冲方式来减少冲击动载荷。一是斗杆尾部加弹簧缓冲,后又改为橡胶垫缓冲,效果更佳;二

First, on the rope push excavator buffer US B-E company in the excavator buffer a lot of research and exploration, on the one hand, on-site determination, on the other hand the use of electronic computer simulation, the use of two methods of determination The difference between the results of less than 3%, as shown in Figure 1 and Figure 2. The test concluded that the computer can be used to simulate the scene. They mainly take the following kinds of cushioning ways to reduce the impact dynamic load. First, the end of the arm plus a spring buffer, and later replaced by rubber cushioning, better effect;
