首次引入综合变形系数和相对硬化特性系数的概念 ,运用类比和试验相结合的方法确定了三通管接头液压挤胀成形力计算公式 ,结果与试验吻合较好。
For the first time, the concept of the coefficient of comprehensive deformation and the coefficient of relative hardening characteristics was introduced. By using the method of analogy and experiment, the formula for calculating the hydraulic forming force of the three-way pipe joint was established. The result is in good agreement with the test.
