 variation calculus
 Using this discrete total variation calculus, we obtain multisymplectic-energy-momentum integrators. A total variation calculus in discrete multisymplectic field theory is developed in this Letter. Thus this theory verifies the conjecture or experience of researchers of mechanics on the integrability conditions in terms of variation calculus. Again using that derivative and also the results of the variation calculus due to M. The control laws are carried out by a variation calculus problem and a polynomial pole placement synthesis solution, respectively. 更多

A mathematical model has been estabished for the fluid flow and heat transfer in TIG full-penetrated Weld pool.Difficulties associated with irregular shape of the deformed weld pool surface have been sucessfully overcome by calculating the surface deformation together with the fluid flow and heat transfer in weld pools. Data of fluid velocity and temperature distribution in weld pools are obtained, so do that of top and bottom pool-surface deformation. TIG welding experiments show that the predictions of the model have a good agreement with the experimental observation with respect to weld pool shape. 根据流体力学理论和变分法原理，推导出了熔透情况下ＴＩＧ焊接熔池上表面和下表面变形的方程。建立了ＴＩＧ焊接熔透熔池流场与热场的数值分析模型，采用非正交贴体曲线坐标系成功地处理了熔池表面的曲面边界。将熔透情况下熔池上下表面变形的计算，与熔池流场与热场的计算相结合，不仅较好地计算出了熔池的流场与热场，同时求得了焊接熔池的上下表面变形。焊接工艺试验表明，根据该模型计算的焊缝成形与试验测试结果吻合程度良好。 in this paper, by adopting the variation calculus on the basis of the principle of minimum potential energy, the minimum axial compression force is obtained and, by using the second-order variation of the total potential energy, the minimum axial force is proved to be the critical pressure for the beam column to lose stability. 本文由变分法中的最小势能原理导出两端铰支的梁柱屈曲时的最小轴向压力，并用总位能的二阶变分说明这个最小轴向压力就是该梁柱的临界压力Ｐｃｒ。 << 更多相关文摘
