Based on analyzing the transient response characteristic parameter B, put forward by Karl Zinner, and covered its shortage, a new modified parameter A was introduced. The turbocharger simulation model was established by coupling control modules GT-POWER and MATLAB/SIMULINK. Influences of these factors, such as turbine mass flow, temperature, turbocharger total efficiency, etc. on the parameter A in the process were studied quantitatively. Variable influencing factors involved in the transient response characteristic parameters A were comprehensively compared. It is concluded that the turbocharger transient response characteristics can be evaluated effectively by the proposed analytic hierarchy process (AHP).

Aimed at the existing conditions that simulation methods of in the field of electric tractor research were non-universal, and the simulation platforms concerned with working units were without complete functions. YTO-500 tractor was selected as the research object, the structural project and the driving parameters of the electric tractor were designed, the simulative platform of extended range electric tractor was established based on CRUISE. By simulating tractive behaviors of the electric and the traditional tractor, and analyzing the surficial behavior and consumption of diesel as the tractor was on a cyclic slow working conditions, the resulting curves express that this platform can simulate tractor's running conditions well. By researching the coupling relationship of torques among its power train, driving train and PTO(power take off), an equivalent model was taken out. Simulation platform of extended range electric tractor's rotary cultivator was established. The simulation expresses that the speed of the working unit approximately maintains 3.65 km/h, the rotate speed of the rotary cultivator's principal axis maintains 200 r/min, the simulation results correspond to the YTO 500 tractor's experiments. By comparison, the speed increases by 14%, and the consumption of fuel decreases by 34.4%. © 2016, CHINA MECHANICAL ENGINEERING Magazine Office. All right reserved.

To solve the cleaning problems of portable reaper, the cleaning system test bench was designed and the wheat was chosen as the experimental object. Air flow test without material was done and analyzed the static pressure in the two stages of pipelines. The relation among the speed of first and second level winnower and the fan can be found. The test can provide the selection scope of motion parameters for the material test. In material test, the fan speed and the first and second winnower speed were selected for test factors, and the cleaning rate for test indicator. Through orthogonal test and quadratic general rotation test, the motion parameters of wheat were found out when its cleaning rate was best and the impact of individual factor on the indicator was researched by regression equation. The best motion parameters can be found through the test: when the speed of first and second level winnower and the fan was 300 r/min, 764 r/min, 3 255 r/min, the cleaning rate would be best. This combination of parameters will apply to portable reaper cleaning systems, and provide the system the reliable movement parameters.

Taking rice as the experiment subject, and making scoop offsetting from feed inlet to ensure the quality of cleaning, the influence of the rotation angle and offset distance of the off-centered inlet scoop on the performance of cyclone separating device was studied. Based on the result of this study, the orthogonal test and regression test were also carried out. Through the performance test on cyclone separating device, the following conclusions were obtained. When the diameter of the cyclone separating tube was Φ=350 mm, the rotation angle of off-centered inlet scoop was δ=150°, the offset distance of inlet scoop was d=35 mm, and the rotation speed of fan was Nf=1200 r/min, the cleaning effect was as well favorable, and the cleaning rate was Yq≥99% and the loss rate was Ys≤0.1%. Through the orthogonal test and regression test, the best structural parameters and motion parameters of the cyclone separating device were obtained as following: diameter of the grain export Φ=160 mm, rotation speed of the fan Nf=1157 r/min, rotation speed of the winnower Ny=1065 r/min, cleaning rate Yq=99%, and loss rate Ys=0.06%.

A decentralized sewage treatment reactor was designed to treat wastewater in rural areas. To examine the factors influencing nitrogen removal, experiments were carried out at three levels of hydraulic surface load, three sludge concentrations, and three environment temperatures at low dissolved oxygen concentrations. The rate of denitrification decreased, and the rate of nitrification increased as the surface load rose. The maximum denitrification rate was 20.01 ± 3.02 g/(m 3·d) at a surface load of 1.11 ± 0.13 m 3/(m 2·h). The total nitrogen (TN) removal, efficiency initially increased and then decreased as the sludge concentration rose. When the sludge concentration increased to 3.5 ± 0.3 g/L, the system showed a good level of TN removal and a denitrification rate of 28.58 ± 1.22 g/(m 3·d) was achieved. Low temperature had a negative effect on the removal and transformation of nitrogenous pollutants. © 2013 Dong-Sheng Shen et al.

A novel decentralised sewage treatment reactor (DSTR) for treating domestic sewage in rural areas was designed and investigated. The reactor was started aerobically after inoculation with biomass; the amount of initial mixed liquid suspended solids was 1.5 g/L. Oxygen was supplied to the reactor and the dissolved oxygen concentration was maintained at 1.3 ± 0.2 mg/L. The pollutant removal performance was investigated, and the average removal efficiencies of total chemical oxygen demand (TCOD), NH 4 + -N, suspended solids, and turbidity were 76%, 77.15%, 84.17%, and 83.93%, respectively. The DSTR exhibited good performance compared with the traditional activated sludge (AS) reactor. The resistance to impact load of the DSTR was superior to that of the AS reactor during surface load experiments. During the 120 days of operation, no sludge bulking was observed. The DSTR effluent NH 4 + -N and TCOD levels were a little higher than those for the AS reactor, but the disparity was not major. © 2013 Dong Sheng Shen et al.
