Development of Green-Naghdi models with a wave-absorbing beach for nonlinear, irregular wave propagation

Two-dimensional and three-dimensional Green-Naghdi (GN) models equipped with a numerical wave-absorbing beach have been developed to simulate nonlinear, regular, and irregular wave propagation. The numerical beach is introduced near the downstream boundary to absorb outgoing waves. An appropriate amount of numerical damping and an appropriate length of numerical beach are investigated using numerical experiments. The results show that the GN models with a numerical beach work very well in simulating wave propagation in water in a small computational domain.

模拟异种钢接头蠕变力学特性的数值分析

利用有限元数值模拟了高强匹配异种的接头在弹性－蠕变条件下的应力／应变场，结果表明，接头的应力／应变分布不均匀，在焊缝界面上，应力和应变分别呈不连续和不协调分布特性，并随着拦头各区蠕变强度差别的增大，其分布梯度增大，峰值应力／应变提高，因此，蠕变强度梯度大的高强焊缝和低强母材的界面是接头的薄弱部位。

三菱FV系列车离合器系统修复后的排气作业

在维修FV系列车过程中，离合器控制油路拆卸、修理、安装后，要对离合器系统进行注油和排气作业，即从离合器助力器排气螺栓排出空气。该车的排气作业不仅仅需要很多工时，而且严重影响修理效率。在详细分析该车型离合器系统的结构和工作原理的基础上，提出了一种高效的排气作业方法。     

Dynamic Simulation of a Smart Crank and Slider Mechanism

In this paper, a smart crank and slider mechanism is analyzed mostly from a dynamic view. By means of dynamic explicit finite element method, 3D nonlinear structure is simulated. It is proved that the mechanism can effectively accomplish smart movement prescribed. And in order to ensure reciprocal movement with higher frequency, measures should be taken to avoid over heating of parts. Compared with internal energy, kinetic energy of total rigid body is dominating, and Y direction equivalent rigid velocity is much higher than X direction velocity. Equivalent rigid velocity of all parts is consistent with respective movement condition. For both energy and velocity, slider effect is dominating. Three direction equivalent inertia force oscillates. Force amplitude in Y -direction is comparitively the greatest.
