为了对液压缸直接作用式隔水管张紧系统样机设计方案进行原理验证,基于SimulationX多学科仿真软件构建了气液回路和多体机械系统的联动模型,分别在正常钻井作业、对称布置的两套张紧液压缸失效和隔水管紧急解脱3种工况模式下对张紧系统开展了动态响应分析研究。研究表明:在正常钻井作业工况下,张紧系统的中位张力、补偿精度、蓄能器气体压力达到设计目标,并满足规范标准的要求;对称布置的两套液压缸失效后,通过增加中位压力值,仍可保持足够的系统张力;在隔水管下部总成和防喷器组发生紧急解脱后,张紧液缸行程小于设计最大行程,活塞和缸体之间没有发生碰撞,蓄能器压力波动基本保持稳定。研究结果对于液压缸直接作用式隔水管张紧系统的研制具有重要的意义。 相似文献

The traditional foundry industry has developed rapidly in recently years due to advancements in computer technology. Modifying and designing the feeding system has become more convenient with the help of the casting software, InteCAST. A common method of designing a feeding system is to ifrst design the initial systems, run simulations with casting software, analyze the feedback, and then redesign. In this work, genetic, fruit lfy, and interior point optimizer (IPOPT) algorithms were introduced to guide the optimal riser design for the feeding system. The results calculated by the three optimal algorithms indicate that the riser volume has a weak relationship with the modulus constraint; while it has a close relationship with the volume constraint. Based on the convergence rate, the fruit lfy algorithm was obviously faster than the genetic algorithm. The optimized riser was also applied during casting, and was simulated using InteCAST. The numerical simulation results reveal that with the same riser volume, the riser optimized by the genetic and fruit lfy algorithms has a similar improvement on casting shrinkage. The IPOPT algorithm has the advantage of causing the smalest shrinkage porosities, compared to those of the genetic and fruit lfy algorithms, which were almost the same. 相似文献

Solidification and fluid flow analysis using computer simulation is a current common practice. There is also a high demand for thermal stress analysis in the casting process because casting engineers want to control the defects related to thermal stresses, such as large deformation and crack generation during casting. The riser system is an essential part of preventing the shrinkage defects in the casting process, and it has a great influence on thermal phenomena. The analysis domain is dramatically expanded by attaching the riser system to a casting product due to its large volume, and it makes FEM mesh generation difficult. However, it is difficult to study and solve the above proposed problem caused by riser system using traditional analysis methods which use single numerical method such as FEM or FDM. In this paper, some research information is presented on the effects of the riser system on thermal stress analysis using a FDM/FEM hybrid method in the casting process simulation. The results show the optimal conditions for stress analysis of the riser model in order to save computation time and memory resources. 相似文献
