This paper discusses the experimental platform building of engine valve movement test based on virtual instrument technology, which is about the experimental course reform on IC Engine Design for undergraduate specialized courses. This paper describes the theoretical basis of the construction of the experimental platform, the overall design of the experimental platform, the implementation of software and hardware, and the final experimental verification.The developed test system integrates signal conditioning, data acquisition, data analysis and management, and can collect real-time waveforms according to the acquisition frequency, time and channel set by the operator, thus effectively improving the flexibility and accuracy of the system. Finally , the article introduces the results of the experimental platform in the teaching practice.
