If finite element models for beam structures of the rail weld CNC fine milling machine are built, and static analysis and modal analysis are used to model the beam structure, it can be concluded that the beam has sufficient margin in strength but lower stiffness. The beam structure is optimally designed with orthogonal test. After optimization, the beam body has been obviously improved in stiffness, and reduced lightly in weight.

HIGHLIGHTS The mechanism of straw smashing was analyzed. Factors such as the speed of the cutter shaft, the number of blades, the thickness, and the inclination angle had a greater impact on the theoretical length of the straw section after crushing. Based on the straw crushing mechanism, the structure of the crushing chamber was designed. The corn stalk crushing and sending device was trial-produced and field experiments were carried out. ABSTRACT . In order to further improve the crushing quality of corn stalks, this research designs a corn stalk crushing and throwing device. First, it introduced the overall structure and working principle, and analyzed the crushing mechanism of corn stalks to obtain the main factors affecting its crushing performance. Then, the crushing blade in the crushing chamber was designed to determine that the number of crushing blades was 10. Kinematics and dynamic balance analysis, and the establishment of a mathematical model, the speed range of the crushing cutter shaft was 530~900 r/min. On this basis, the ADAMS motion simulation software was used to measure the change curves of the restraint force, runout, and acceleration of the shaft end with different speeds of the crushing cutter shaft. The simulation analysis finally determined that when the speed of the crushing knife shaft was 700 r/min, and the working performance of the device was better and meets the requirements of dynamic balance. Finally, the verification test was carried out, and the result shows: when the speed of the crushing knife shaft was 700 r/min, the qualified rate of corn stalk crushing length was 93.65%. Compared with the original silage corn crushing and throwing device, the performance had increased by 4.78%. It meets the standard of corn stalk crushing operation, which can provide a theoretical basis and scientific basis for the design and optimization of corn stalk crushing and returning equipment.

As the demand of marine resources is continuously growing, more and more people are focusing on the study of underwater towed system for marine survey, in which mastering and predicting the dynamic characteristic of the system is the key problem. Based on the parameters of a certain underwater system, combined with the lumped mass method, the underwater cable-body 3D motion mathematical model has been established by OrcaFlex, in which the variation of the tension of the towed cable and the variation of the depth of the towed body have been given and the effect of the towed speed on critical radius in the process of the 360° rotary motion has been discussed. The results show a good agreement with previous research results. At the same time, we also make a research on the effects of the change of the hydrodynamic coefficients and the parameters of towed cable on variation of the tension and towed depth. These studies can provide a basis for the selection of cable in the system.
