| Abstract: | The railway development towards high speed and heavy loading transportation leads to higher requirement for the performance of locomotive diesel engine. To ensure the reliability of diesel engine, the static strength of piston is analyzed. A 3D finite element model of the piston in a diesel engine is built by HyperMesh and the finite element analysis is performed on it by ANSYS. Considering the coupling of the heat load and mechanical load, the dangerous positions with maximum stress or maximum deformation are determined. The analysis results can provide references for the diesel engine piston design of locomotive. |
