Portable Formaldehyde Detector Based on MSP430 Microprocessor
Formaldehyde is a colorless, strong irritating smells of gas .It is a strong toxic chemicals and carcinogenic, teratogenic-type material. The formaldehyde and other indoor air pollution from interior decoration and furniture has become a major source of serious impact on human health. Therefore, the analysis of formaldehyde detection is particularly important. Phenol reagent spectrophotometric assay [...]
Study on the Background Deduction Method in Gamma-ray Spectrometry Data and Software Development
The background of NaI(Tl) gamma-ray spectral data is very complex. The affecting factors include cosmic radiation, environmental background and Compton scattering effect produced by the interaction between gamma-ray and other material. All gamma-ray characteristic peaks are added on the background. Therefore the separation of all peaks from the background is a key technology. In this [...]
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 [...]
Dynamic Simulation of Hydraulic Servo-Control System of Ring Rolling Mill
Ring Rolling Mill is a kind of machine processing ring shape workpiece. With the guide roll, local plastic deformation is taken place on the workpiece, and this makes the workpiece thinner and the diameter of it bigger. Finally the required shape is got. Ring Rolling is widely applied in areas of machine, automotive, metallurgy, ships [...]
Study on Condition Monitoring of Hydraulic Pump on the Basis of Resistance Analysis
Fluid power plays a decisive role in a variety of industrial plants and it is almost impossible to find a manufactured product that hasn’t been”fluid-powered”in some way at some stage of its production or distribution. Safety and functionality of a hydraulic system can considerably be increased by implementing condition based maintenance routines based on automatic [...]
Dynamic Analysis and Simulation of the Automotive Air Compressor’s Crank-Rod Mechanism
Crankshaft is one of the key components of piston compressor, which endures complex and alternating load, so it has complex dynamic characteristics and impacts compressor’s reliability and life directly. Therefore, it has important practical significance to analyze the crankshaft from the theoretical and practical point of view. The simplified method of traditional design and analysis [...]
The Development of Parametric Finite Element Analysis Software for the Steel Structure of Circular Stacker-reclaimer
All along, the Bucket, circular stacker-reclaimer FEM analysis, are used to design the program first, then design the finite element calculation device model based on the program. Equipment as a result of the establishment of a detailed calculation of the finite element model of a large workload, therefore, in the design of the results of [...]
Worm Drive Principle and Research for New Type Involute Spiroid Gearing Pairs
Cone worm drive is applied in a wide range, especially in the conditions of the compact structures, which require high transmitted power, high ability to bear impact strength, smooth operation and adjustable backlash over the middle transmission ratio or above. Compared with the other forms of gear drive ,Cone worm drive has a more compact [...]
The Designing of Automatic Flat System and Subsidiary Function of Loader Buckets
With the rapidly development of technology, Mechatronics as an advanced technology has been widely used in all kinds of engineering machinery in recent years. The loader is an important branch of engineering machinery, is one of the main machinery in bulk cargo constructed of engineering construction. However, the scooping of the loaders’are mainly completed by [...]
The Tooth Bending Fatigue Life Prediction of the Main Reduction Gears of Ship Unloader
The ship unloader in the department of transportation undertakes the important task of transporting the production of raw materials into the plant. The stability and reliability of its operation determines wether the raw materials can be unload and sent to plant in time.Gears are the main parts of shipunloader gearbox. Once damaged, the user often [...]
