| Abstract: | It is pointed out that quality of a Polycrystalline Diamond Composite is one of the factors affecting on the life of PDC bits. Analyzing the technical development, structural components, damageable formulations, and theoretical design methods about the mould used in PDC production. according to the actual structure of the mould, the calculating method is given by means of finite element analysis and the calculation results including stresses, displacement, and pressures between any two components about the Multi-component compound cylinder. The accuracy of the results of finite element analysis is checked through actual tests. The method and software are being put into use in industrial practice. |
