Numerical analysis of thermo-mechanical characteristics of solder joint depending on change in solder junction structure of MCP

Various of cable elements are used in the numerical analysis of cable structures. According to the mechanical characteristics of highline cable system of alongside replenishment at sea, two cable elements are investigated: catenary element, which is the exact solution, and parabolic element, which is the approximate solution but simpler to calculate. The equilibrium equations of each cable element are introduced, and the expressions of tangent stiffness matrix are derived. The tangent stiffness matrix of catenary element is calculated through Newton interactive method.

And Performance

Based on the configuration and mechanical characteristics of piezoelectric actuator, the bidirectional piezoelectric variable friction control device which can produce control force in two orthogonal directions was designed and the relation equation of control force with input voltage for this control device was presented. Finally, one piezoelectric variable friction control device was manufactured and performance test of this control device was processed. The result of numerical analysis and experiment shows the bidirectional piezoelectric variable friction control device can produce semi-active control force fast, and the performance of this control device do not change when the frequency of input excitation varies and the control force of this control device has stable mechanical properties.

Traditional Arrangement

Nowadays market demand for storage racks are becoming larger and larger in China, especially in logistics industry. Hold-welding beams are important components in storage racks, and searching for more reasonable solder joint arrangements on them is a problem. On the basis of traditional arrangement, this paper came up with another five schemes with differences in solder joint numbers and location. Then ANSYS was used to analyze the mechanical behavior of the beam in every scheme. According to the numerical analysis results, the most reasonable scheme was recommended.
