Dynamic Deformation of Thin-walled Plate with Variable Thickness under Moving Milling Force

Stable Milling of Thin-Walled Parts with Variable Dynamics

The milling of thin-walled parts can become a seriously complex problem. In this work, the problem of the variable dynamics of a test part has been solved through the calculation of 3D stability lobes which add a third dimension with the tool position along the part, to the traditional depth of cut-spindle speed pair. First, the dynamics of a test part in several machining steps have been calcu...

Prediction of Dynamic Milling Stability considering Time Variation of Deflection and Dynamic Characteristics in Thin-Walled Component Milling Process

Dynamic Analysis of Moving Cables with Variable Tension and Variable Speed

Dynamic Analysis of an axially moving cable with time dependent tension and velocity isstudied in this paper. Tension force and the moving speed are assumed to be harmonic.It is found that there exists a specific value of speed in which natural frequency of the system approacheszero. This specific speed for such a critical condition is called critical speed and it will be proved thatincreasing ...

Thin elastic shells with variable thickness for lithospheric flexure of one-plate planets

Planetary topography can either be modeled as a load supported by the lithosphere, or as a dynamical effect due to lithospheric flexure caused by mantle convection. In both cases the response of the lithosphere to external forces can be calculated with the theory of thin elastic plates or shells. On one-plate planets the spherical geometry of the lithospheric shell plays an important role in th...
