摘要：针对浙江某企业汽车差动继动阀产品合格率较低的问题,本文利用专业模流分析软件Procast对产品现有的压铸结构工艺进行数值模拟研究,观察铸件充型过程和模拟结果,分析缺陷成因。以此为依据,对原铸件压铸结构进行优化设计。结果表明:改进后的铸件毛坯结构能改善该产品的缺陷问题,提高其合格率。

摘要：针对目前市场上康乐办公休闲椅结构设计的非合理性以及其存在的强度问题,根据人机工程学的相关理论,对康乐办公休闲椅坐背联动机构进行方案设计,并利用有限元软件对其进行静态力学分析,优化相应的结构和尺寸。最后借助专业检测设备,对样机坐背强度进行检测。结果表明:经过ANSYS Workbench优化后的结构能通过BIFMA的测试标准。优化改进椅背机构后能够满足强度要求。
