According to the main problems of nonlinear driving control and driving force calibration of pure electric vehicle, based on the research of permanent magnet synchronous motor control method, on the vehicle's driving force calibration techniques were studied, from the high efficiency and energy saving analysis of necessary driving force calibration, designed a new driving force calibration method, and drew the control curve of the accelerator pedal opening and the speed and the motor torque relationship between the three, and finally to pure electric self-developed to test platform for automotive related experiments. The experimental results show that, in the vehicle driving process, the driving force calibration technique compared with the previous calibration has better performance, while no obvious change of acceleration performance, the current value of the initial acceleration phase have been greatly decreased, could make the vehicle run more energy efficient, extended battery life and vehicle driving mileage. © (2014) Trans Tech Publications, Switzerland.

The book transporter innovation to improve the efficiency of the modern library book classification is an important aspect. In this essay, Based on the research on the electric control system, a DC motor as a metal belt stepless automatic transmission was adopt to greatly reduce the number of parts the system and improve overall efficiency, response speed and control precision ratio, thus library books for transportation vehicles designed control system, enabling the driver, speed and other functions. Software such as the Solidworks was applied for designing body shape, includes a handle, a frame, wheels, support frame, a 'W'-shaped support frame was proposed, it can be installed to increase the capacity of the trolley, a pedal was added at the bottom of the trolley, the user can stand on it to save effort. The electric trolley placed the book has simple structure, easy to use, saving manpower, high efficiency, and has good practical value. © (2014) Trans Tech Publications, Switzerland. Source

E-ACE (acrylic elastomer) is a kind of material so far in electro-active polymer (EAP) in the most excellent performance. Based on the analysis of the basic principle of the E-ACE power generation, the feasibility is studied on E-ACE power generation principle to achieve energy recovery and damping. Design a model damping device of vehicle for energy recovery based on E-ACE. Through analysis, when the system vibrates near the resonance frequency, deformation of spring is greater, E-ACE materials to move up and down reach the larger amplitude, and the more energy it produces. To analysis the system about harmonic response by ANSYS software, get the relationship between spring stiffness K, damping coefficient C and external incentive, then analysis the resonance frequency of the system. The simulation results verify the feasibility of the design scheme. Results show that E-ACE has excellent performance in the automobile vibration energy recovery and vibration. E-ACE will have broad application prospects. © (2014) Trans Tech Publications, Switzerland. Source

Considering the efficient use of energy and environmental pollution, people's lives tend to energy saving and environmental protection, and energy saving electric vehicles has gradually been widely used. Through combining theoretical analysis, numerical simulation, system design and experimental validation, based on studying electric vehicle body design principles, the experiment optimized electric vehicle body design, and reduced the weight of the vehicle effectively. Its performance becomes more advanced, and the application becomes more economical and safe. By using Solidworks software, lightweight electric vehicle body structure of two-dimensional design and three-dimensional modeling was built to reach practical requirements. The body structure design is original and simple, which has good practical value. © (2014) Trans Tech Publications, Switzerland. Source
