Confronted with global energy crisis and environmental deterioration, residence regeneration has attracted more and more attention for dealing with the ageing urban residences. On the reference of electromagnetic field theory in physics, the mathematical formula of field force of residence is established. We demonstrate that " field force" F is proportional to "residential Value"...
On the basis of reasonably simplifying the structure of disc cutter, the rolling force is used as the vibration source and based on equivalent stiffness method, the method to establish a general vibration differential equation of rolling rock in the rolling direction is further discussed. Through theoretical derivation, a conclusion can be drawn that the range of the vibration frequency is ωf-1.414ω...
This paper combined the finite element method with theory of reliability design and applied the PDS module of ANSYS to establishing 3D parameterized model of shield cutter. What's more, it compiled the APDL command flow and obtained the reliability documents to analysing the reliability of shield cutter. It can be obtained the reliability of shield cutter and influence degree of different parameters...
