中文摘要:根据船板厚度及宽度的不同,设计了一可调式柔性船板折弯模具,并建立了模具的有限元模型;采用接触法对折弯模具的可靠性以及船板弯曲力和模具的受力、应力应变情况进行了仿真分析。仿真及实验结果表明,所建立的有限元模型是正确的,所设计的模具能够满足使用要求。
英文摘要:A flexible ship-plate bending press die was designed according to the different ship-plate thickness and width, and the finite element model of the die was set up. The reliability, stress and strain status of the die were simulated by contact method. The numerical simulation and experimental results show that the finite element model is correct and the designed die can satisfy the use requirement.
