Table 1 Structure parameters of the crankshaft crankshaft material QT-800-2 quality(Kg) 12.618 length(mm) 305 main journal diameter(mm) 70 connecting bar neck journal diameter (mm) 65 eccentric distance (mm) 59.5 Fig. 1 Mesh model of crankshaft Crankshaft Finite Element Model.
Two main journals bears constraints from bearings, output side bears constraints in axial direction and circumferential direction.
The fatigue analysis of crankshaft is based on static analysis; the maximum stress is much lower than material yield strength, so the crankshaft fatigue problem is attributed to high cycle fatigue.
The detailed steps are: create a new project, set alternative stress as “equal stress (Von Mises)”, average stress as “Gerber” [6], considering material real S-N curve has some deviation from theoretic curve, fatigue reduction factor are determined as 0.9, set material property as QT-8000-2 fatigue S-N curve, interpolation method as “double-log”, maximum loads as “total reverse”, maximum circulating times as 107.

The material of rubber is smashed and kneaded by mixer with different-speed meshing movement between main mixer shaft and the cleaning shaft.
Fig.2 The finite element model of the mixer shaft 1.2 Mechanics Analysis As known as mixing principle, the mixer shaft can be deformed under the exciting force acting on the mixer shaft surface when the mixer shaft smashing and kneading materials [3].
Here, material of shaft is carbon steel [5], its main attribute is shown in table 1. 2.2 Model building, Element selecting and Mesh dividing The full-scale mock-up of mixer shaft is built by Solid Works.

The most widely used and least expensive polymer resins are the polyesters and vinyl esters; these matrix materials are used primarily for glass fiber-reinforced composites.
As the raw materials of the composites are liquid and glass hollow spheres, the flexural test specimens were cast to shape.The mixture of glass powder, resin and accelerator was blended with mechanical blender to ensure a more homogenous mixture.

Recently, LCD of IT fields, DVD discs also lead the demands of MMAs’ composited materials to quickly increase.
The suspension copolymerizing reaction conditions was studied in this thesis, effect factors of resin yields and properties in water medium, like initiator kinds, reaction time, dispersants, also, used a new dispersant, organic-montmorillonite (O-MMT), which can not be found in references, made the polymerization technics become better. 2 Experimental part 2.1 Materials Styrene (St; A.P.

However, titanium alloys are typically difficult-to-machine materials because of their toughness and low thermal caonductivity[4].
For now, micro-EDM is a widespread technique used in industry for high-precision machining of all types of conductive materials of whatsoever hardness[5].
