位置保持

A number of numerical examples and applications were presented to verify the proposed Bezier-Based Element Method. The engineering cases include: the belt die for diamond synthesize, the main frame of wire-rounded press, the oil cylinder of open die forging press. The numerical results show that the BBEM has some good performances. With few elements, the BBEM can lead to a high accuracy. If using same DOFs, the computing precision of BBEM is remarkable higher than that of the conventional FEM.

通过大量的数值算例来考证所构建的各种类型单元，并应用于人造金刚石年轮模具、钢丝缠绕预应力机架和液压机工作缸等实际问题的结构分析；结果表明：所构建的Bezier耦合单元具有描述较大梯度变化场（如位移场、应力应变场等）的能力，该方法不改变单元的大小和形状，保持单元的自由度数不变，而通过调节中间可动节点的位置改变单元内部的场分布，只需少量单元即可较精确地模拟较大的梯度变化；可为有效求解高梯度问题提供新思路，对实际工程应用具有重要意义。
