Study On Application For Impoving A Systematic Design Method Of Railbound Vehicles Hvac Based On Ce Environment

We face the challenges of a constantly evolving environment driven by increasingglobalization. Market shifts and customer consolidations as well as massive price and costpressures. How to shorten the product development period, improve quality of product andreduce cost, which becomes very important basic to enhance the competition ability ofenterprises. Therefore, is to design the development method with the concurrentEngineering technology to quickly and appropriately address customer needs throughgreater efficiency and effectiveness.This thesis studies the train air-conditioning products, describes the structure andcharacteristics of the product, analysis of the company’s existing design process defects.For different defects, the establishment of a new design for concurrent engineeringmethods and parallel processing part of the process, be improved. In the following areas:In the proper time to pass the right information to right people on a right way basedon the Client/Server network and wide web environment via PDM method. The productdevelopment team can share couple of data and work in parallel at the same time.To divide product to three parts composed by structure, cooling system and electricalsystem conducted with detailed design process parallelization, there are serveral teams arebuilt to design together. Assembly of product and the accuracy of BOM are sufficientlyconsidered during design, the lower department and early validation can find the bugsimmediately, so the rework and scrap will be decreased due to inappropriate design.Through concurrent engineering design for manufacturing, to consider makingmodularity of products, simplifying the design model, in order to reduce manufacturingcosts and convenient for maintenance.By analogy with empirical data, parallelization of system design process can greatlyaccelerate the design and improve design accuracy in new projects. Evaluation of the final product availability, consistency of customer requirement andcompliance of relevant standards can be validated in CAE, it can parallelize design andvalidation.
