Imageware and Pro/E Based Reverse Engineering Techniques for Drawbar in Heavy-Duty Railway Freight Cars
As a new for heavy-railway vehicle connecting device, drawbar can eliminate connective gap and improve dynamic performance of the train obviously as it is well interchangeable, simple structure, easy manufacture, convenient maintenance, mature technology, high reliability, and widely applied abroad. Through the research on reverse engineering of foreign drawbar, authors present data collecting method based on the coordinates measuring machine (CMM) and data preprocessing by Imageware software, which including noise points removal, data alignment, simplification, sorting and benchmark transformation. Converting points cloud data by Pro/E independent geometric module, 3D models based on features and constraints were reconstructed, which support the redesign of parts and their manufacturing analysis. The outcome of the paper provides effective ways in terms of drawbar techniques digesting and absorption, and also supports innovative design of new products.
