作为一名独立的工程材料顾问，我提供的咨询服务范围从参加几次会议到项目附带的长期合同。同时提供工程设计CAD服务;2022足球世界杯预选赛时间针对中小型企业和初创企业，他们可能没有内部的能力，但需要在整个项目生命周期内生产零件和组件的CAD图纸。凭借独立所提供的灵活性，我的服务可以精确地根据您的需求进行定制，以及您需要多长时间;2022足球世界杯预选赛时间使其成为聘请专家或固定期限承包商的成本效益替代方案。我很高兴为完成的任务报价，按小时收费，或在“取消”合同的基础上对整体计划和成本限制。材料选择材料选择应该在设计周期的早期阶段进行，但经常被忽视，导致项目延迟，随后增加成本。选择最合适的材料取决于许多因素和通常的强度、韧性等参数之外的几个因素。在产品设计中，材料选择的主要目标是在满足产品性能目标的同时使成本最小化。系统地选择最好的材料，为一个给定的应用开始所需的性能。 These should be defined in the Product Design Specification (PDS), with no reference to materials at the PDS stage. For example, a thermal blanket must have poor thermal conductivity in order to minimize heat transfer. Systematic selection for applications requiring multiple criteria is more complex. For example, a rod which should be stiff and light requires a material with high Young's modulus and low density. If the rod will be pulled in tension, the specific modulus, or modulus divided by density, [E / ρ], will determine the best material. These properties also have to be ratified against the cost of the material and available production techniques for shaping and forming. A systematic approach to materials selection will be applied to your project, which will ensure that all design parameters are satisfied while minimising costs to the project. CAD CAD has become the "norm" for drafting in the engineering arena. The advantages of using CAD are numerous, but the key advantages are the flexibility and ease at which new designs can be turned into drawings and existing designs can be modified during the design process. These make CAD an essential tool in the engineers box. In the product development space, the extended features in modern CAD software are also useful visualise a product. Overall, CAD is a tool for increasing productivity, improving quality, and reducing costs. When combined with Computer-Aided Manufacture (CAM) via CNC machining equipment and, more recently, 3D printing technology, CAD can give a company options to send their model data to suppliers to get things made remotely, with just a phone call or two to confirm details, etc. This advantage is able to reduce costs by allowing suppliers to be situated anywhere in the world. I have three CAD packages that can be deployed on your project, depending on the project budget. I use AutoCAD and Salome, the latter used to create meshes for later analysis by FEA. So, depending on your needs, whether it is a one-off paper-design-to-CAD exercise or a longer term product development exercise, I have an efficient solution. FEA For engineering designs, Finite Element Analysis (FEA) is a natural follow-on from CAD. FEA allows the design (or modified design) to be analysed against its performance parameters without the expense of producing working test items. Modern FEA software includes a graphical user interface for model creation, meshing and post-processing. the calculation engine is usually "hidden" from the user and will require very little interaction, save to check the model parameters and solution accuracy. Load cases can be applied to the design and the response of the component analysed. These analyses can be fed back into the design, which can be modified accordingly. The design - analysis cycle can then be repeated as often as necessary before a working test device or prototype is made. The use of modern CAD and FEA tools makes it very quick and cost-effective to iterate design modifications and analyse them. For FEA, I use "Code-Aster" on a 64-bit Linux platform. Code Aster is an FEA tool developed and used by French energy company EDF. It is highly versatile and is capable of numerous post-processing options to allow detailed analysis of your design.
