By Dorothy Snodgrass Monday January 30, - Suddenly I had all this loose time on my hands, driving me absolutely bananas!
However, these benefits come at a cost. This study analyzed the energy consumption and emission of pollutants at every stage of the EB life cycle production, use, maintenance and recycling by using Life Cycle Assessment LCA.
The environmental impacts and the energy consumption in production and use were quantified and compared with other competing modes of transport, such as bicycles, buses, motorcycles and cars.
The results show that the energy consumption and emissions of pollutants by EBs occur mainly in the use stage, and specifically in the process of electricity production and battery change. The emissions of pollutants by EBs per person per kilometer are several times smaller than the values for motorcycles and cars, more or less equivalent to buses and higher than bicycles.
It combines the power and transmission systems to simultaneously provide functions of power generation and transmission for electric bicycles. The brushless DC hub motor is an exterior-rotor type permanent-magnet motor.
A two-dimensional finite-element analysis package was used to facilitate the motor design and performance analysis. The rotor yoke is integrated with the drive member of the transmission hub to form a compact mechanical part.
The transmission hub consists of a basic planetary gear train providing three forward speeds including an under drive, a direct drive, and an over drive.
Each speed stage is manually controlled by the driving sleeve to selectively engage or disengage pawl-and-ratchet clutches based on the clutching sequence table. The number of gear-teeth for the transmission hub is synthesized and the results of an analysis of the power flow path at each speed stage are provided.
The results of this work are beneficial to the embodiment, design and development of novel electromechanical devices for the power and transmission systems of electric bicycles.
Through analyzing the main damage mechanism of the electric bicycle users, the speed, vehicle type, road type and road status were determined to be the higher electric bicycle safety weight factors in the closed-loop system of driver-vehicle-road.
The program of vehicle traction test was developed with the test security ensured. A multivariate test on the main influential factors was conducted with orthogonal design. Systematic analysis of the insecurity mechanism of electric bicycles on road was made.
Based on a large amount of experimental data, a friction coefficient database of overturned electric bicycles in a variety of road conditions was established. The result show that the most significant impact factors on safety of the electric bicycles were velocity, vehicle motion, vehicle type, road type and road condition, and the velocity was the greatest factor on safety.
In general, a BMS of a battery pack in electric bicycles has no communication with chargers. In such system, the battery pack is charged without taking the voltage of individual cells into account and such system works well when charging with normal charging current level.
In contrast, for fast charging, one cell may suffer overvoltage rapidly during charging with high current. This can lead to shortened life-time or sudden damage of the battery. In order to avoid the mentioned problem, the charging process is executed using measured data from the BMS. The developed charger adjusts the charging current to the maximum possible limit corresponding to the voltage of the cell which has the highest voltage in the pack, so that no individual cell suffers overvoltage during charging.
The proposed scheme was implemented and tested. The hardware prototype and the experimental results validate the functionality of the proposed scheme. Plan, Design, Build, Manage, and Maintain May 25, - May 27, The increasing popularity of the use of electric bicycles in China in recent years has transformed the urban traffic travel structure, changing the impacts on the natural environment from the traffic system.
By analyzing the energy consumption and emissions from various traffic modes during life cycle, this paper discussed the impacts energy consumption, carbon emissions, SO 2, PM and pb consumption onthe environment from the transformation of urban travel behaviors caused by the development of electric bicycles.
However, energy consumption and CO2 emissions were reduced.
The bicycle kickstands considered were the side stand and bracket stand. A cylindrical solenoidal pickup and a solenoidal bar pickup are proposed to be housed in the side stand and bracket stand respectively.
Two primary pads are proposed for each of those pickups. Each of these configurations are simulated and analyzed. It is shown that a solenoidal bar pickup with a Double-D provides the highest coupling while the solenoidal bar pickup and primary appears to be the cheapest option, utilizing the least amount of ferrite and copper.
A Double-D primary pad with a solenoidal bar pickup was built and practical measurements were shown to match with simulation. There is a large body of research relating to cycling related activities and mostly these consider the common diamond "safety" framed bicycles.
There are a number of areas that could benefit from direct input from ergonomics, including the redesign of braking grips for drop handlebars on road bicycles, and the verification and validation of products for specialist performance.
The design of bicycles for human wellbeing and performance comes into question with the ubiquity of standard upright "safety" bicycles when compared with the performance and ergonomic benefits of recumbent bicycles.
The assist control for commercial electrically-assisted bicycles is basically a proportional control. The proportional control leads to torque ripple and speed fluctuation due to the crank of pedals. Slowing down caused by speed fluctuation may cause falling over. Hence, this study proposes a repetitive-control-based driving torque assist algorithm to reduce torque ripple and speed fluctuation.Aug 30, · Essay on Multinational Companies; Essay on Multinational Companies.
