摘　　要：在文[1]的基础上，本文建立了金属成形工艺非耦联系统和相似非耦联系统的物理模拟虚功原理及余虚功原理，并从该两原理出发导出了文[1]所建立的物理模拟变分原理。上述诸原理共同组成物理模拟能量原理。而物理模拟虚功原理及余虚功原理是物理模拟能量原理的统一理论。同时，给出了模拟虚功原理的应用。On the basis of a reference [1], virtual work and complementary virtual work principles of non-coupled systems and similarly non-coupled systems for physical simulations in metal forming technology are established, and the variational principles for physical simulations given in the reference [1] are derived from the two principle. Energy principles for physical simulations consist of all aforementioned principles. And the virtual work and complementary virtual work principles for physical simulations are united theories of the energy principles for physical simulations. Meanwhile, applications of the virtual work and complementary virtual work principles for physical simulations are given.
