根据上限定理之应用——上限元法,设计了符合金属流动规律的空间截锥刚性基元体的上限模式,解决了轴对称挤压变形力的上限估计问题.经验证,用所得公式计算的上限解很接近真实解,使挤压力的计算精度大为提高.
The design of a mode of the spatially truncated rigid cone element to con-form with the metal flow was made by the application of the upper bound the-ory-upper bound element technique.The problem to estimate the upper bound ofaxisymmetric extrusion deformation force may be solved consequently.Solutioncalculated by this mode after trial done on practice is in agreement with the actu-al one and the precision of calculation of the extrusion force seems to be muchimproved.
