Active machinery monitoring – continuous supervising, diagnosing, managing, controlling, compensating, documenting- is a process of acquiring and transferring streams of information (usually source information) about the analysed object, process, and relations between the same and the environment that can be used to realize the postulated state: knowledge creation (theory and innovation), environment melioration (harmfulness) and technical system optimization (design) - depending on technology needs and engineer imaginations. Knowledge creation comes as result of the creative action (creating). Melioration means the intentional activities of a technical system and boundary zone; activities that enhance, improve, and restore properties of the environment and not only limit technological harmfulness. Optimum comes in property of the machinery design (construction) or system state with respect to the criteria that enable rational evaluation of the state. Active monitoring, investigations into multi-disc grinders, demonstrate that it is possible to acquire knowledge of, describe and utilize, for design and structural purposes, the characteristics that indicate the relations between speeds, idle movement, loads and the indicators of motion variables in the grinding space. The objective of this example is to provide a mathematical description, optimisation of the states and changes in the grinding grains and machine space, their surface and volume during movement (idle and working movement) of the components, and design assemblies in the multi-hole grinding process.

This article introduces two ways of calculating the transmission parameter of the mechanical system in the aircraft based on the traditional computational method. One is the method of fixed point coordinate which is based on spatial Analytic Geometry and spatial coordinate transformation can calculate the motion parameter of various links, the effective radius of the limit position rocker as well as the transmission ratio by fixed point coordinate. The other method can establish the model of control system by using the MDT module of the three-dimensional mapping software CATLA. It also can realize analog computation and system optimization which points at the transmission parameter of the mechanical system by using DMU module.

Applied FLUENT simulation software to research the influence of tunnel length, tunnel entrance velocity, tunnel equivalent diameter and tunnel buried depth four important factors on the tunnel wind cooling system in Shenyang area. The results show that, with the increase of tunnel length and tunnel buried depth and with the decrease of tunnel entrance velocity and tunnel equivalent diameter, the outdoor air which passed into the tunnel cooling amplitude increases. For the tunnel wind cooling system optimization design in Shenyang area and the surrounding areas, the advices are that tunnel buried depth should not be more than 6m and tunnel entrance velocity should not be more than 5m/s.
