The feeding device is an important part of the briquetting machine, and their work ability affects the capacity of the forming unit directly.
The screw diameter D: (1) In the formula, D—Screw diameter （m）；Q—output quantity （T/h）; γ—material bulk density （T/m3); Ψ—fill factor；K—Coefficient of material property；C—Correction factor.
According to the material properties, take parameters: K = 0.060,Ψ=0.2~0.25, A=30, C=1.0, the screw diameter: m (2) The screw diameter should be rounded up to the standard series, therefore, take the standard value D=0.25 m.
Primaries n = 60 r/min and check the fill factor: (4) Now Ψ=0.17<0.20～0.25, so reduce the speed of the screw conveyor n= 45 r/min and check the fill factor again: (5) Ψ is within the set range, so the speed of the screw is determined as n=45 r/min.

Damage is considered as weakening of the structure that negatively affects its performance and can be defined as any deviation in structure's original geometric or material properties that may cause undesirable stresses, displacements or vibrations on the structure.
In all the cases damage can severely affect safety and serviceability of the bridges.

Mechanical micro-cutting is a fabrication method for creating miniature devices with high profile accuracy, surface finish quality at reasonably low cost.
In micro scale, the nose radius could be the same as the grain size and the workpiece material property cannot be looked as uniformity.
The results indicated that the temperature was an important factor in micro cutting due to its influence on the flow stress.
Material Modeling The flow stress is mostly influenced by temperature, strain, strain rate, and other factors.
The material property can affect the cutting temperature and the Mises stress observably.

Meanwhile, under the premise to meet the strength, lightweight design is adopted realizing the mechanical properties when running at the maximal speed of 24km/h[2]
In the choice of battery parameters, battery type, battery voltage and battery capacity are the main factors considered.
But because of the weight of the battery pack increaing, the weight of vehicle will increase, leading to the increase of the driving resistance, which in turn affects the driving range of the vehicle.

If the imbalance of tangential force is too large, the billet will produce the distortion [2].Therefore, during the actual rolling asymmetric shaft-parts by CWR, the designers often design the die through their experiences, which will result in trial and error for gaining suited die parameters, and the lack of theory will hinder the smooth progress of the rolling process and affect the mechanical properties of products [3-7].
Therefore, we must fully consider the above factors when establishing FE model so that the rolling procedure in MS-CWR can be expressed more accurate.

Three Dimensional Parametric Design Of The Die Channel For Plastic Extrusion Based On SolidWorks Hui Gao a, Zailiang Chenb and Xin Zhang c Department of Mechanical Engineering, Soochow University, Suzhou, Jiangsu, 215104, China agaohui3037@gmail.com, bchenzailiang@suda.edu, czxanm2003@163.com Keywords: Die Channel; Parametric Design; SolidWorks.
The design intention could be reflected more intuitively and comprehensively based on 3D CAD(Computer Aided-Design) software.Futhermore,the use of 3D solid-modeling can improve the efficiency and quality of design,shorten time-to-market and reduce product development costs[1,2] There are many excellent 3D modeling software,all of them can realize the model design.However,there is still a lot of repetitive work in the process of designing the building models.The fundamental reason is as follows:the size of these models is needed to change according to different customers,but the topology is essentially the same,which greatly affected the product development cycle.To solve such problems,one of the key technologies is parametric design technology.
Die Channel For Plastics Extrusion The geometrical property of product is greatly affected by the performance of extrusion die.
The difficulty in die design arises from the large aspect ratio of the product geometry of polymer extrusion process.In order to get uniform thickness of product,the extrusion die has to be designed to produce uniform flow rate distribution at die exit in the transverse direction.In industry there are three kinds of extrusion die commonly used,they are T-die,fish-tail die and coat-hanger die.Among them coat-hanger die is preferred ,thanks to its superior flexibility of geometry which is very important factor for the achievement of higher performance.
