摘要
本文对圆环镦粗法测定摩擦系数的实验方法和处理实验数据的各种方法进行了总结比较.在线图法处理实验数据的基础上,提出了理论计算法,并对铅、铝两种材料在有无润滑剂条件下进行了圆环压缩试验,比较了用线图法和理论计算法对实验数据的处理结果,指出了各种方法的优缺点.本文认为,理论计算法是一种较好的处理实验数据的手段.
The experimental methods and data processing for measuring fric- tion factor by means of upsetting ring have been summarized and com- pared in this paper. Parallel to the nomographic method, the numeri- cal calculating method is also put forward here. As an example, the lead and aluminium rings are pressed with oil lubrication or with- out. The results of data processing by nomogram and the numerical calculating are compared. The advantages and disadvantages of those methods have been pointed out. It seems that the numerical calcula- ting method is better.
