The mixture powder of Ultra-high molecular weight polyethylene (UHMWPE) and graphite was blended into nitrile–butadiene rubber (NBR) to be modified to develop a new kind of compound water lubricated rubber bearing with cost-effective, low-friction performance. In order to study the tribological and vibration performance of the new material, a series of experiments were carried out on the test rig...
Aggregates are food for construction industry and hydraulic and hydropower engineering, account for 80% of concrete. Now the number of artificial aggregate systems of being used and preparing to put into use is considerable, which calls for an efficient method to assess the environment impact. In this paper eight factors are taken into consideration to set up a factor set, which includes wastewater,...
Artificial aggregate systems are used both by aggregate producers and the mining industry. It is a multi- attribute complicated system which has many uncertain or fuzzy factors, which means constructing a practical and satisfactory mathematical model for computer simulation and optimization is difficult. To achieve optimal performance of an artificial aggregate system, equipment Selection and coordination...
