In order to improve the handling and stability of four-wheel-steering (4 WS) vehicle, a new 4 WS intelligent control system with genetic algorithm (GA) fuzzy neural network (FNN) was put forward. According to the tire cubic formula, a vehicle nonlinear dynamics model was built. Then a vehicle model based on back-propagation (BP) network was identified from(More)
Aerobic granules were successfully cultivated in a sequencing batch reactor (SBR), using a single bacterial strain Rhizobium sp. NJUST18 as the inoculum. NJUST18 presented as both a good pyridine degrader and an efficient autoaggregator. Stable granules with diameter of 0.5-1 mm, sludge volume index of 25.6 ± 3.6 mL g(-1) and settling velocity of 37.2 ± 2.7(More)
In order to improve automobile transfer efficiency, we design a fuzzy control strategy based on genetic algorithm. Acceleration is taken as a control parameter of automatic transmission upshifting or downshifting, namely that only when acceleration is positive, automobile can be upshifted, only when acceleration is negative or zero, automobile can be(More)
The control of off-line fuzzy neural network can realize the shift of multi-parameter automatic transmission in construction vehicles. The method is based on fuzzy look-up table database. The gear shifting dynamically acts according to the shift database. The database was established by training the fuzzy neural network and was save in advance. The shift(More)
In some mechanical transmission structures, the conjugate cam mechanism is used widely. The previous design method is not only tedious, but the substantial design is not strong, difficult to form a simulation animation, and inconvenient for subsequent analysis. The equations of conjugate cams curves are derived by the analytical method. Taking the conjugate(More)
Belt conveyors are widely used in the areas of coal, ports, electric power, chemical, etc, to transport bulk solid. The traditional design methods have many defects, such as long design cycle, prone to error, and it is unable to meet the needs of modern society. This paper presents a new method of designing belt conveyors, the 3D visual rapid design(More)
The excessive vibration of motor support in container crane’s machine room affects lifespan of the structure and driving comfort of the operators. According to the result of the vibration site test, the main causes of the machine room vibration in container crane were found out. In order to reduce the vibration response, based on simplifying the system as a(More)
With the market competition increasing, in order to shorten product development cycle and reduce the development costs, product design is changed from the traditional serial-type process to the parallel, collaborative development process. Food product collaborative design of Feature modeling refers to the number of the design team through the division of(More)
Characteristics of clutch engagement at different engagement stages were different, so different control methods were used in different stages. At quick engagement stage proportional control was used. Control system of starting acceleration stage was serious non-linear and it was difficult to establish precise mathematical model, so fuzzy control was(More)
