The objective of this paper is to study the effect of high damping aluminum alloy on dynamic stability of Nipper Mechanism, in order to improve its stability of motion. Based on Euler-Bernoulli beam theory, the partial differential equation of motion with damping was formulated. According to Floquent theory, Galerkin's method and Fourier series method were then applied to obtain the stable and instable...
The fault diagnosis in tribosystem was a difficult problem due to the complex structure of the tribosystem, the nonlinear character of the tribosystem and the presence of multi-excite sources. Usually, one method of fault diagnosis can only inspect one corresponding fault category. In this paper, oil monitoring and vibration monitoring methods were utilized together to diagnose the rolling bearing...
Oil monitoring technology is a useful method in condition monitoring and fault diagnosis for the machine, especially for low-speed, heavy-load, reciprocated and lubricated diesel engine equipment. But it is difficult to implement intelligent diagnosis because monitored information lacks logical relationship in oil monitoring. To solve this problem, the theory and method of case-based reasoning is...
