摘要

The significance and the necessity of virtual prototyping are discussed. The main fault modes that affect firing performance of machine are analyzed, and three principles of performance evaluation are brought forward based on limited firing conditions. With the application of Fortran language, the simulation module of main faults is programmed, and the virtual prototyping model is provided by using ADAMS. By the means of AHP, The weighted coefficients that affect synthetic performance are achieved, and the evaluation plan of machine performance with virtual prototyping is established. Therefore, the life of machine can be further predicted, the life prediction model is verified effective by simulation results. Finally, the research perspective of next step in the future is presented.
