The rheological characterization of fluids using a rheometer is an essential task in food processing, materials, healthcare or even industrial engineering; in some cases, the high cost of a rheometer and the issues related to the possibility of developing both electrorheological and magnetorheological tests in the same instrument have to be overcome. With that in mind, this study designed and constructed a low-cost rotational rheometer with the capacity to adapt to electro- and magneto-rheological tests. The design team used the method of continuous improvement through Quality Function Deployment (QFD) and risk analysis tools such as Failure Mode and Effect Analysis (FMEA) and Finite Element Analysis (FEA). These analyses were prepared in order to meet the customer’s needs and engineering requirements. In addition to the above, a manufacturing control based on process sheets was used, leading to the construction of a functional rheometer with a cost of USD $1500.

低成本旋转流变仪开发中的持续改进过程

使用流变仪对流体进行流变学表征是食品加工，材料，医疗保健甚至工业工程中的必不可少的任务。在某些情况下，必须克服流变仪的高成本以及与在同一仪器中同时进行电流变和磁流变测试的可能性有关的问题。考虑到这一点，本研究设计并构建了一种低成本的旋转流变仪，它具有适应电和磁流变测试的能力。设计团队使用了通过质量功能部署（QFD）和风险分析工具（例如失效模式和效果分析（FMEA）和有限元分析（FEA））进行持续改进的方法。准备这些分析是为了满足客户的需求和工程要求。除上述内容外，
