轴瓦的试验应力和位移计算

Experiment Research and Compatation for the Testing Stress and Displacement of Bearing Shoes

研究了多层金属材料轴瓦，在试验载荷作用下合金层的应力和加载点的位移；建立了组合曲梁的应力和位移计算公式，并和有限元法及电测法的计算结果进行比较，它们之间相差很小，由此证明这些公式完全满足精度要求。

The stress of alloy layer and the displacement of the loaded point on metallicmultilayer materials bearing shoes on which tesling load is exerted have been researched. The computing formulas of the stress and displacement of the combined curved beam areestablished.Compared with finite element method and electrometric method,the results ofthe above caloulation seem to have good effect,from this,these formulas are proved to meetthe precision preseribed completely.
