Abstract: In engineering design,designers need to learn a lot of simulation analysis software and must have special knowledge of other disciplines.To reduce the designer’s burden from modeling,we developed a network service platform that can help designers to complete the computation task for engineering design.On the Web-based service platform,designers can choose a parametric design model constructed by other professionals,customize the external function connections,input model parameters,and view the visualized simulation results of remote computation in servers.The platform has been applied to the modeling and simulation of engine thermal and dynamical processes.The results show that the service platform can do a lot of simulation work for designers in this field,greatly reducing the modeling workload and improving the design efficiency.Meanwhile,the problem that designers have difficulty for constructing the correct model due to lack of sufficient expertise can be avoided.
