The future mining machinery manufacturing system is no longer a single enterprise combined with the steady state of the limited suppliers long-term cooperation, but without borders, many enterprises, short-term optimal dynamic system.

 

The mechanical structure health since detection and health diagnosis

 

The traditional mechanical structure without life, without intelligence, cannot perceive external function and internal injury, can't make a proper response to protect themselves make the structure is in the best condition, so the external load and the change of the environment, and the influence of natural and man-made factors, will make the structure performance degradation and damage, serious threat to people's life and property. Along with the development of the information and material science and technology, scientists and engineers to fundamentally solve the engineering structure in the whole life cycle of security, a comprehensive structure to improve the performance of the new train of thought, introduce the concept of intelligent structure and system. Smart structure state of perception in the form of biological structure and external environment, and make judgments, and adaptive response in time.

 

The structure of the mining machinery health life safety directly affects the safe production in mines and the miners, mining machinery structure since the detection and diagnosis system USES integrated sensors, controllers and actuators for the integration of smart structures, adaptive gave structural health diagnosis, environment, and damage the repair some intelligent functions and vital signs, to enhance the structural safety, reduce quality, reducing energy consumption, the purpose of improving performance, is the direction of the major mining machinery products online monitoring in the future.

 

Mining machinery green design

 

Specific measures of sustainable development strategy of mining machinery is: (1) the adoption of long life, low energy consumption and the design principle of weight. Extend the life of the product, can reduce the mechanical production and reduce the scrap quantity; Reduce energy consumption of products, can reduce pollution to the environment; While lightweight and high efficiency can reduce the consumption of materials and resources. (2) with low environmental load material as far as possible, as far as possible don't use freon (air conditioning), chlorinated rubber, resin and harmful material such as asbestos. Minimize waste pollution of parts and components processing and comprehensive cost optimization, mining machinery products in the design of the initial stage to consider scrapping a simple processing, low cost and low pollution, zero, parts easy to collapse, crushing easy, can burn or can be used as a fuel recycling, etc.; (3) can use recycled materials and resources, especially the design of the structure should be used as far as possible, easy to assemble and decomposition of big modular structure and non-toxic materials, improve the mechanical material regeneration rate; (4) to reduce vibration and noise of the machine, reduce the pollution to the environment.
