elastic structure
2.The extended order state variable forms of dynamic equations of visco-elastic composite structure have many advantages, such as simple in formulation, easy in programming, and fast in calculating.
6.In order to reduce the losses suffered from collision between passenger trains,a new design method for the car body structure of motor car and trailer is advanced.Car body structures are made up of three parts with diffferen tstiffness,by carefully designed.The parts of the front and the end are the wea kstiffness structure to absorb energy through plastic deformation in the collision.The middle part,where only elastic deformation occurs,is an elastic deformati on structure with strong stiffness.As the passenger train runs normally,car body structure measure up to regulation of intensity and stiffness in the standards.

8.DISCRETE ELASTIC MODEL FOR CRYSTAL DISLOCATION CORE STRUCTURE AND P-N FORCE
10.In this magisterial thesis, the author selects the elastic component shape and designs the elastic component. After selecting the elastic component shape suitable for the structure of the machine tool, elementary design is implemented for two kinds of component material: 40CrNiMn & LY12. Then the analyse of the elastic component stress and strain is completed, and the check of the component age limit and strength follows.
