Design improvement of Sofa Structural Components based on load path analysis considering cost & weight efficiency

Palliser是一家设计和制造高品质家具的当地顶级制造商。像Palliser这样的家具制造商面临着设计和制造高质量产品的持续挑战，这些产品既要满足或超过客户的期望，又要对业务具有成本效益。为了应对这种情况，Palliser正在进行产品重新设计，以提高成本效率，同时保持/提高高稳定性和轻量化产品的质量。在本项目中，将对沙发框架结构的荷载传递路径进行分析，以指导结构设计，提高承载能力，提高成本和重量效益。首先将建立该结构的有限元模型。将考虑和校准附加到车架上的不同软材料的不同加载条件。然后应用载荷传递路径分析工具U*对沙发框架有限元进行静力分析，以找出将施加的载荷传递到框架不同位置的准确载荷路径。在精确加载路径的指导下，我们将对沙发框架结构进行新的设计，并将制造出原型并进行测试。新的设计应该具有更好的结构强度和/或成本效益，并指导他们的类似产品和结构的设计。**********

Palliser is a top rated local manufacture designing and making high quality furniture. Furniture manufacturers like Palliser experience a constant challenge of designing and manufacturing high quality products that meet or exceed customer expectations while being cost effective for the business. To deal with this situation, Palliser is working on the product re-design to improve cost efficiency while keeping/improving the quality of the products with high stability and light weight. In this project, load transfer paths analysis of a sofa frame structure will be conducted to guide the structural design with enhanced loading capacity as well as cost and weight efficiency. A finite element model (FEM) of the structure will be built first. Different loading conditions with different soft materials attached to the frame will be considered and calibrated. A loading transfer path analysis tool, U*, is then applied to the static load analysis of the sofa frame FEM to find the exact load path transferring the applied load to different positions of the frame. With the guidance of the accurate load paths, we will have a new design of the sofa frame structure, and a prototype will be fabricated and tested. The new design is supposed to be with better structural strength and/or cost efficiency and guide the design of their similar products and structures. **********
