Aiming at the problem of insufficient maintainability design method of EMU engine, a method of using virtual simulation to verify maintainability design is proposed. This paper mainly studies the quantitative evaluation method of maintainability index, and provides the quantitative evaluation method of accessibility and operation space based on virtual maintenance, the quantitative evaluation method of maintenance human factors and the calculation method of maintenance time. Combining with the characteristics of EMU engine system, the scheme design of virtual maintainability design software system for EMU engine is carried out, and the specific process of maintainability verification is given. The efficiency and quality of engine maintainability design and evaluation are effectively improved, and the development cycle is shortened. It is an effective method to realize the parallel optimization design of engine maintainability for EMU.
