Loads Equalization Based on Optimization Principle and the Hierarchical Model for Distribution Networks

Loss reduction is important for distribution networks and it is available to reduce loss by loads equalization. With increasing numbers of vertexes in distribution networks, compounding of loads are rapid increasing. It is hard to achieve the global optimization for load balancing by traditional model of distribution networks. Base on analyzing character of loads equalization for distribution networks, this paper provides a new method which conjugate the optimization principle and the hierarchical model of the distribution networks, can transfer the optimization issues into multi stage decision making problems,and can also achieve the optimization equalization of the distribution networks loads.     

Parameter Design for the Power Train and Simulation of the Dynamic Performance of Elctrical Vehicle

The method and principle of the parameter design for the power train of EV is explored and discussed,then the parametersof EV. based on SC7101 are reasonably selected.The method of calculating the SOC of Lead_acid battery is provided and the relation among the electromotive force,the interior resistance, the polarized resistance and the SOC are analyzed. The capacity is compensated according to the relation between the capacity and the temperature, which is the basis on which the energy management system is designed and improved. The dynamic model which reflects the dynamic characteristics of the power train is established,then the dynamic performance of the EV based on SC7101 is simulated, and the factors that affect the continuous mileage of EV are analyzed,the measures to increase the continuous mileage are provided.The result shows that the analysis of the electric characteristics of battery and the dynamic model are correct,and the dynamic performance perfectly meets the need of the design target.

The validity of this model has been verified by the simulation experiments and analysis. The simulation helps to forecast the dynamic characteristic to high pressure startu Poil pum Pand have some directive significance to design method of lubricating oil system.     

Analysis of Causes and Impacts of Soft Budget Constraints of Enterprises Based on Dynamic Game for Three Players

This paper researches the behavior difference among government,banks and enterprises and how it affects soft budget constraints of enterprises and non-performing loans of banks based with dynamic game.The game model suggests that government will give banks some assistance and let them refinance enterprises,especially government has strong(incentive) to sustain SOEs in China's transitional economy.Banks will do it if the assistance from government is more than the loss from refinance enterprises.In addition the value of liquidation of enterprises and the new loans affect banks' refinancing old enterprises.     

A NEW METHOD OF RESEARCHINE THE SITE DUPLE FACE DYNAMIC BALANCE OF MACHINE RIGID ROTATOR BASE DON AMPLITUDE MEASUREMENT

In this paper, a new method of researching; the site dupleface dynamic balance of machine rigid rotator, namely duple test weightmethod is presented. Weight the new method against the existing method,namely single test weight method [1], both the efficiency increasing and theenergy-consumming dicreasing would be forty percent and over, with thebasic points of vibration theory, the formula of calculating weight andposition of the duple face dynamic unbalance of a rotator by means ofapplying the duple test weight is developed in detail. The method in handll-ing distinct bearing form is also discussed. Rightness of the new method isproved out by the living example of the simulant contrast testing carried outn the dynamic balance test machine and the site balance for a rotatorsystem of motor.

工况对发动机排气门失效的影响

发动机排气门在高温冲击环境下工作，恶劣的工况环境是使排气失效的重要原因之一。虽然在这种工况下，环境介质、气门机构的动力学特性都可使气门早期失效，但大量的研究表明：在正常情况下，影响气门失效的主要工况参数是温度及冲击次数。为此，讨论了汽车发动机工况对排气门失效的影响；探讨了进一步提高其使用寿命的有效途径。
