A new pipe rupture valve for hydraulic elevator is designed. Mathematical models established for the hydraulic elevator system are used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameters, inlet pressures of pipe rupture valve, and elevator loads on the hydraulic elevator system s dynamic performance are analyzed. Experimental research is also carried out using a hydraulic elevator experiment rig. The numerical simulations accord with experimental results in general. Dynamic performance indexes are assessed by the EN81-2 standard. The results show that the newly designed pipe rupture valve meets the designing requirement for hydraulic elevators.

Knowledge representation is the core of artificial intelligence research. Knowledge representation methods include predicate logic, semantic network, computer programming language, database, mathematical model, graphics language, natural language, etc. To establish the intrinsic link between various knowledge representation methods, a unified knowledge representation model is necessary. According to ontology, system theory, and control theory, a standard model of knowledge representation that reflects the change of the objective world is proposed. The model is composed of input, processing, and output. This knowledge representation method is not a contradiction to the traditional knowledge representation method. It can express knowledge in terms of multivariate and multidimensional. It can also express process knowledge, and at the same time, it has a strong ability to solve problems. In addition, the standard model of knowledge representation provides a way to solve problems of non-precision and inconsistent knowledge.
