For the hull section, in order to ensure the balance and rhythm of the logistics operation and then match the logistics operation, it is necessary to optimize the designing according to the lean production concept, which is under the premise that the construction process is relatively fixed. This paper is based on the principle and method with leading type of work decomposition, with the help of the...
The purpose of this paper is to compare the ability of solder joint with different shape (hourglass-shaped, barrel-shaped and cylinder-shaped) to resist destruction under drop impact loadings. Three 3D finite element models of VFBGA (very-thin-profile fine-pitch BGA) packages, including different shape of solder joints, are established respectively. According to the condition B in the drop test standard...
Product failure distribution research is a basic research for product advanced design and manufacture, and has an important role in intelligent computing. Traditional analysis of the failure distribution about small samples has some limitations, for example, the weibull distribution test is better as the sample size is more than 10; the Figure test is better as the sample size is more than 20; the...
This paper deduces a remarkably precise analytical formula for calculating the fundamental resonant frequency of V-shaped cantilevers using Rayleigh-Ritz method. This analytical formula, which is very convenient for MEMS sensor design, is then validated by ANSYS simulation. This formula raises a new perspective that, among all the V-shaped cantilevers, the simplest triangular cantilever can lead to...
This paper presents an approach of modeling for Fiber Optic Micro Cable (FOMC), constructs a coupled nonlinear model for Remotely Operated Vehicle(ROV) connected with FOMC, and makes computer simulation at last. The model of FOMC takes use of the lumped mass method in which FOMC is considered to be a system of micro units connected by elastic non-mass spring. Four order Runge-Kutta method is used...
