Introducing a suitable model for a structure to understand its behavior under different conditions of loading is very important. Mathematical modeling is the simulation of a physical structure or physical process by means of suitable analytical or numerical construct. One of suitable methods for finding deflection of a beam under different forms of loading is Finite Element Method (FEM). In this paper...
Armoured face conveyor is a key component of the comprehensive mechanized coal mining equipments which has the characteristics of large size and heavy duty. The chain transmission system is adopted to transport material from the coal face. Three dimensional geometry model of the chain transmission system is built by Solidworks software including the chains, sprockets and axles. Based on the geometry...
The piled wharf on slope may impacted by the deformation of soft soil foundation, the lateral displacement of pile cap would increasing because the deformation of soft foundation, which would threaten the safety of wharf structure. The creep is one of the important factors, so it is meaningful to research the creep characteristics of slope. In this paper, the deformation damage of piled wharf and...
Based on the engagement principle of cycloid ball planetary transmission (CBPT), the load distribution mechanical model of engagement pair is established in condition of multi-teeth engagement, and the coefficient of load distribution of teeth is presented. The finite element model of engagement pair is established in condition of four points contact. The stress distribution of engagement pair in...
The theoretical analysis of finite element method for buckling phenomenon to finite-sized shell structure is first introduced. Then, a real application using a probe for detecting the pressure inside turboprops is analyzed thoroughly with ANSYS10.0, including section profile, dimensions, and local characteristics. Based on the solved results, several rules between critical load and influence factors...
The forces of the ship-based helicopter are analyzed comprehensively in the winds and waves. The parameterized FEM model about the ship-based helicopter body, the mooring cable and the mooring base is established with the language APDL. The parameterized FEM model is used to calculate the tension of the mooring cables for different sea conditions. The mooring cable will present strong nonlinearity...
