Taking Motorcycle Engine as the research object, force analysis of the single cylinder engine connecting rod bending and fracture by engine linkage dynamic model. By calculating the connecting rod compression, combustion chamber total pressure, reciprocating movement of the inertia force and from the rod bend parameters to compare the models currently on the market four types in the working state suffered total stress and strength margin safety factor, found that the safety factor of four models in general partial link is small, especially 152QMI engine connecting rod end connecting rod in the hole near easier to bend and break. This study provide a scientific basis for the engine connecting rod design, the quality of correction and failure analysis.

The internal combustion engine should be enlarged the cylinder diameter for the Power requirements. In order to ensure the engine to work normally, it is needed to compute the strength of the connecting rod. Through adopting ANSYS software, the three-dimensional computational model is constructed, and the stress analysis is carried out. We can learn the stress field of process of deformation. Through calculation the stress and strength of connecting rod are derived. Using the stress which was calculated from ANSYS we can decide the Safety of connecting rod. In general, the analysis is meaningful to optimize the design of connecting rod.

Blind forensic-investigation in a digital image is a new research direction in image security. It aims to discover the altered image content without any embedded security scheme. Block and key point based methods are the two dispensation options in blind image forensic investigation. Both the techniques exhibit the best performance to reveal the tampered image. The success of these methods is limited due to computational complexity and detection accuracy against various image distortions and geometric transformation operations. This article introduces different blind image tampering methods and introduces a robust image forensic investigation method to determine the copy-move tampered image by means of fuzzy logic approach. Empirical outcomes facilitate that the projected scheme effectively classifies copy-move type of forensic images as well as blurred tampered image. Overall detection accuracy of this method is high over the existing methods.
