摘要
在横观各向同性假设条件下．借用弹性力学的半无限平面体边界上受力作用和圆柱体均布载荷作用的结论，导出静压作用下重组木坯料形成的受力关系式，并用试验验证了这些结论。应用这些理论，可以精确计算重组本木束形成达到临界状态时的最大应力，并可建立其强度准则。结论还可以用于重组木坯料加工设备的参数确定和丰富木材学的基础理论。
Under the isotropic hypothesis from horizonal view in this paper,used the conclusions that the force acts on the boundary of semi-infinite plate body of theory of elasticity and uniform load acts on the cylinder,the rela-tive force formular about the formation of scrimber blank acted by static pressure have been derived and conclusions have been verified through tests.Applied these theories,the maximum stress when wood web of scrimber are formed and reached the critical situation can be calculated acchmtely,and the intensity criterion can be established.the conclusions in this paper elso can be applied to the parameters establisment of manufacturing equipment for scrimber blank as well as rich the basic theories of wood science.
