With the speed increase this year, locomotive wobbling occurred frequently due to side abrasion of straight rails at switch point.

随着线路的再次提速，因固定型提速道岔转辙部位直股钢轨侧磨而多次引发机车摇晃。

For extrudates there are side crushing strength tests, bulk crushing strength tests, abrasion tests.

对挤条产品有侧压强度的测试，堆积强度测试和耐磨测试。

At last I calculate the life indexes and fuzzy reliability indexes of side-abrasion failure of rod string failure, and analyze them generally.

再利用模糊可靠性理论计算管杆偏磨失效寿命指标和模糊可靠性指标，最后对其进行综合分析。
