Rolling bearings are one of the most important noise and vibration generator into mechanical constructions. Therefore, it is very important to have knowledge of the rolling element bearings influence on the level of noise and vibration in this systems. This paper deals with a basic forms for generation of vibration and noise of rolling element bearing and suggestions of vibration analysis signi...

Bearings are mechanical dissipative systems that, when perturbed, relax toward a synchronized (bearing) state. Here we find that bearings can be perceived as physical realizations of complex networks of oscillators with asymmetrically weighted couplings. Accordingly, these networks can exhibit optimal synchronization properties through fine-tuning of the local interaction strength as a function...

Quantitative risk assessment of landslides has always been the focus and difficulty in field landslide research. In this paper, taking Mayang County, Hunan Province as an example, rainfall-induced was carried out from regional individual scales. On scale, factors geological disasters were analyzed. Based on slope unit, analysis vulnerability hazard-bearing bodies to form block plan. based rainf...

New demands associated with living in a highly-technological and globallyof competencies than previous generations of students needed. The general goal of education is to prepare young people to live independent and productive lives. Unfortunately, our current educational system is not keeping pace with these changes and new demands. The world is becoming increasingly complex and to make progre...

The optimum design of a flexible rotor supported on three-lobe bearings, overhung centrifugal compressor, is studied for the optimal unbalance response using the genetic algorithm (GA) and method of feasible directions (MFD). The MFD is used to verify the GA results. The feasibility, effectivness, and avaliability of the GA is certainly of value because it allows the exploration of many differe...
