Abstract. The treatment and utilization of straw is a considerably complex type of problem in agricultural production. A mobile pellet harvester integrates the mechanisms of picking, drying, crushing, and pelletizing, thereby solving the problem caused by the traditional method and reducing human effort and material resources. The crushing mechanism of a mobile pellet harvester was designed and studied, and the shape of the hammer slice was innovatively proposed, thereby substantially improving the working efficiency during the crushing process. Ansys finite element analysis software was used to perform static and dynamic analyses of the key components of the crushing mechanism (i.e., hammer slices, hammer framework, and crushing spindle). These components have sufficient rigidity, strength, and good dynamic balance to meet the working requirements of the straw pulverizer.

Structural and dynamic analyses of a new machining fixture help Porsche AG get production up and running faster. Porsche contracted with KTW Konstruktion Technik K. Weisshaupt GmbH of Friedrichshafen, Germany, to design and produce the fixtures required to hold automobile motor parts in place during drilling and high-precision milling. It has been noted that using a 3-D computer-aided design (CAD) solid modeler can point out weaknesses before a design leaves the computer. In order to avoid the need for costly generations of prototypes prior to the casting process, Speedy Engineering in Immenstaad, Germany, used finite element analysis software to perform linear static and dynamic (vibration) analyses of the motor component fixture geometry within only a few days of its design, to determine displacements and eigenfrequencies of the geometry. The results of the static and dynamic analyses enabled Speedy to specify maximum working loads for •production, which guaranteed success with the first use of this fixture design.

Shock Processing

Welding residual stress is one of the main factors that affect the strength and life of components. In order to explore the effect on residual stress of welding line by laser shock processing, finite element analysis software ANSYS is used to simulate the welding process, to calculate the distribution of welding residual stress field. On this basis, then AYSYS/LS-DYNA is used to simulate the laser shock processing on welding line. Simulation results show that residual stress distributions of weld region, heat-affected region and matrix by laser shock processing are clearly improved, and the tensile stress of weld region effectively reduce or eliminate. The simulation results and experimental results are generally consistent, it offer reasons for parameter optimization of welding and laser shock processing by finite element analysis software.

The explicit dynamic finite element theory is applied on the collision of ships with buoys for computer simulation. Using ANSYS/LS-DYNA finite element analysis software, the numerical simulation of the collision between the ton ship and the buoy with different structures and impact points. The collision force, deformation, displacement parameters and the weak impact points of a buoy are obtained. Based on the numerical simulation results, analysis of buoys and structural collision damages in anti-collision features are discussed, and several theoretical sugestions in anti-collision for the design of buoy are provided.
