Research on product system design process based on PA66 composite material
To explore the application advantages of composite material in the product development process,the design and development of bicycle wheel was proposed based on PA66 composite material as an example.In the task description stage,PA66 composite material was introduced to clarify design requirements and constraints.In the concept explanation stage,the Analytic Hierarchy Process was used to analyze the weight of design requirements to output multiple wheel schemes.The optimal scheme was evaluated by multiple simulation software.In the stage of structural improvement,the overall structure of the wheel was improved based on material properties.In the manufacturing and simulation stages,joint simulation tests were conducted according on material characteristics to obtain the optimal wheel design.The research results indicated that under the guidance of the product system design process based on PA66 composite material,the overall wheel met the structural strength requirements,with a maximum reduction of 16%in single wheel mass.Moreover,for every 0.5 mm reduction in spoke wall thickness,an additional reduction mass of about 6%could be achieved,which reduced material consumption and production cost while compared with the initial plan.This research method could provide systematic theoretical guidance for the development of similar products.
