Dynamics Analyzing on Slender Rod Machining by Axial Turn-milling

The experiment on finish machining the slender rod with weak rigidity by the orthogonal turn milling and the turning were done respectively.

According to horizontal vibration theory of beam of u- niform section,the kinetic model of the orthogonal turn-milling slender rod is presented,and according to the peculiarity of the turn-milling cutting force,the simplify cutting force model is presented.

The curvature formula of tiny curved rod,together with the vector method of area,is applied to inference for Euler formula about critical load of slender compressive rod which one end is fixed and another is free.

The equilibrium condition of slender compressive rod with tiny curvature,together with the curvature formula,is applied to inference for the equations both of slope and deflection,which apply to all kinds of slender compressive rod.

Study on the long slender member bar construction technological planning of rigid arched bridge;

Experimental study of flutter stability of H-shaped slender member

A geometrical relation between longitudinal displacement and transverse displacement of a Euler's pole is(obtained) by Lagrange's description method,and a nonlinear dynamic model expressed by partial-differential equations is(established.
