本文研究了小钎头体受力的情况及其静态和动态的应力测定。测定结果表明,钎头体主要是由切向应力引起账裤破坏。这个结论为钎头体正确选用钢材和制订合理的加工工艺提供了依据。
In this paper, we study the stress of small bit body and its static and dynamic stress measurement. The measurement results show that the bit body is mainly caused by the tangential stress damage to the pants. This conclusion provides the basis for the correct choice of steel and the development of rational processing technology.
