In order to improve vehicle driving function, the author establishes a three-dimensional model of a sedan McPherson front suspension with ADAMS / CAR, besides, there is an analysis on the wheel vertical beating positioning parameter variation of the suspension when driving. With the evaluation of the rationality of the suspension design parameters, reaching the common method for the analysis and optimization of the vehicle suspension based on ADAMS, by which, we can improve the function of the vehicle suspension system, and save time to design the vehicle suspension.
In order to solve the engineering application problems of parametric rapidly in design of wind turbine tower, an automatic design method of wind turbine tower is put forward first, and the automatic design model was built through analyzing the key parameters and parameters’ calculation relation in different cases: same taper tower design and variable taper tower design. The key parameters, height, diameter and wall thickness of the tower, are mainly considered. Then, an automatic design system of the wind turbine tower is developed and realized according to the model. Finally, the system effectiveness is verified through taking a wind turbine for example. The results show that the system can enhance the design efficiency and shorten the cycle times at the same time.
To solve the problem on the indeterminacy of customers’ demands, a new fuzzy configuration design based on decision table is presented. Generalized product configuration model is proposed and taken as the basic of configuration design. Generalized product configuration model is composed of generalized product structure BOM,structure-function units and configuration rules. Configuration rule is expressed with decision table, and it constrains the process of the configuration design. Fuzzy theory is applied in configuration design. Configuration engine accesses decision table and carries out the configuration reasoning with fuzzy theory in configuration design. Finally, the application on the transmission system of wind turbine verifies the feasibility and validity of this method.
To obtain rational environment adaptability design solution of wind turbine, a fuzzy environment adaptability design method of wind turbine based on core design platform is promoted. Firstly, the core design platform is built based on main structure of wind turbine irrelevant with environment factors. Secondly, the 1:n mapping relationship between environment factor set and environment adaptability technology set is created. Thirdly, the fuzzy relationships between environment adaptability technologies and environment factors are researched, and the relationships include dependency and contradiction. Finally, the quality function deployment (QFD) technology is used to obtain rational environment adaptability design solutions of wind turbine in the known condition of complicated environment factors. The feasibility and availability of the method above mentioned are validated by an example.
In order to improve the design efficiency of wind turbine tower, a design method which combines configuration and parametric design is proposed, the general structure model of wind turbine tower is given, and the parameter relation model of tower components is established. Based on skeleton and coordinate system coincident method, the automatic assembly of 3D tower model is realized. An automated 3D design software system of wind turbine tower is built by the API of Pro/E. The validity of the system is proved by wind turbine SUT-1500.
