Abstract: A mechanical-electrical-hydraulic coupling dynamic model of ramming system was built by using MSC.Adams and Easy5. Its confidence was proved by using VV&A. A virtual prototyping-Monte Carlo simulation-support vector machine (VP-MCS-SVM) method was proposed to reduce the large computational volume of MCS method in solving the random dynamics of complex system，and the random dynamics simulation of ramming system was carried out efficiently and precisely. Based on the theory of statistic inference and reliability, the action reliability of ramming system was analyzed and the distribution parameters’ shift was considered. It provides a new idea for the action reliability evaluation for large complex system.

Key words: applied mechanics, action reliability, mechanical-electrical-hydraulic coupling, ramming system
