Study on Designing Optimized about Window External Shade Device of Resident Building
Along rapidly development of our country economic, the contradiction of energy is more and more obvious, architecture energy-consuming is increasing gradually while urban residential living standard is improving. For easing energy crisis and coming true sustainable development, it is necessary to realize architecture energy-saving in the premise of providing high living standard to the urban [...]
Optimization Design of Cowshed Structure with Large and Medium-sized Span Portal Frame
Large and medium-sized homes portal frame structure of cowshed is one of the widely applicable agricultural buildings at home and abroad, and compared to the structure of the traditional cowshed, it possesses the characteristics of light weight, space, environmental advantages, short construction period, low cost and so on. However, unreasonable building parameters of cowshed and [...]
Practical Analysis and Design Technology of PWM Switching Power Supply
The trends on miniaturization, low power, and high efficiency have grasped the low-voltage electrical devices together with the switching power supply.There are two objectives of this thesis: (1) One is based on their advantages and disadvantages to analyze the structure of power supply control IC, from testing one simple low dropout regulator (LDO) to focusing [...]
Simulation Analysis and Structure Research on Synchronization Valve Based on AMESim
In recent decades, with the development of aerospace engineering and modern machine building industry, there has been increasing demand for synchronous drive technology. Among them, hydraulic control system of synchronous, with the advantage of high precision, fast response, and great anti-load rigidity, has attracted widespread attention. The synchronous hydraulic control technology now has been intensively [...]
The Study on Operation Optimization of Regional Highway Hinges
Transportation is the precursor of the economy development. With the rapid development of the modern social economy and the improvement of people’s living standards, we should improve transportation to be the higher level, it need establish the sufficient, high efficient, good service, safe and proper transportation system, and build a modern integrated transportation system, so [...]
The Finite Element Analysis and Optimization for Connecting Rod of LJ276M Electronic Controlled Gasoline Engine
As one of the most important parts,connecting rod endures the power thrusts from piston pin with its magnitude and direction change periodically,the inertia force caused by swing of connecting rod and the reciprocating inertia force of piston group. Therefore,the connecting rod suffers alternating loads such as compressive load, tension,load,bending load and so on.It requires the [...]
Experimental Study of Single-layer Filter Backwashing Process Optimization
Filter backwash is an important part of filter regeneration in water treatment process. The quality of backwashing will have a dramatic effect on the filtration process. In previous studies, lots of research direct response to filters, and the study of the regeneration of the media – backwashing are relatively small. In this paper, we made [...]
Extension of Ground Source Heat Pump in Different Districts and Its Optimization
Nowdays people pay more attention to the ground source heat pump, because it can save a lot of energy, protect environment and have no thermal pollution. A lot of projects use ground source heat pump as cooling and heating source of air conditioning system. But the design of the ground source heat pump usually use [...]
Matching and Optimization of W375 Torque Converter
With the development of the automobile industry, due to their own excellence hydraulic transmission technology has been widely applied in cars and construction machinery industry at home and abroad. At present, the hydraulic transmission of the internal combustion engine vehicles using the working conditions are far from their best work in the region, failed to [...]
Simulation and Optimization Study of Discrete Production System Based on the Petri Net Modeling
Production system is a complex system, which integrates production process, production planning, quality control, staff scheduling, equipment maintenance, materials control etc., to produce one or a certain category of products. How to describe and optimize the production system is the key to succeed in production management , and to change from labor-intensive to knowledge-intensive for [...]
