摘要：The idea of preparing this special issue aims at solving emerging problems when condition monitoring is applied to more and more machines running in practical harsh environments. Such machines, including wind turbines, mining and civil engineering machinery, are not easy to be frequently checked and maintained by man power. Most established machine condition monitoring are developed in ideal lab-setting conditions. Considering the real-world highly dynamical load and harsh working conditions, there is a need to develop practical ways to handle various situations and rapidly response to the faults and significant degradation process.
