Apparently, the research of rubber crack propagation direction was not very sufficient, three-dimensional crack propagation of rubber material has not been reported so much.
G.J.Lake [6] etc. studied the fatigue fracture of the rubber material systematically; defined the absorbed energy of crack expanding per unit area as the energy release rate (tearing energy) G (Eq. 1)
Fig.1 Jmax Finite element model Bead rubber specimen crack growth direction Jmax Criteria validation Selected the wear-resistant layer rubber material (TVE) in bead, prepared specimens according to national standards (Fig. 2), preset 6mm initial crack in geometric center of the two rubber samples which direction relative to external force were 90° and 45° respectively.

Analysis on Industrial Chain Forming mode of traditional industrial chain Traditional industrial chain is a typical linear chain, roughly divided into five links: raw material suppliers, parts suppliers, machine suppliers, wind farms and power departments [3].
(Notice: The score of each lattice is the ratio of tandem factor and rampant factor) Table 1 Discrimination matrix analysis table of critical success factors New raw material Parts assembly technology Machine manufacturing innovation …… Score Weight New raw material Parts assembly technology Machine manufacturing innovation …… Score Weight To sum up, the critical success factors are independent innovation capability of machine manufacturing, technical standards and certification system, reasonable generation price, improved grid-connected electricity, incentive policy and perfect service system.

Conclusions The process for synthesis of glutaraldehyde from cyclopentene, a by-product from oil-chemical industry and coal chemical, as starting material using tungsten acid-boron anhydride as catalyst and 30% hydrogen peroxide as oxygen source was studied.The optimal process prometers were selected follows mass ratio of tungsten acid to boron anhydride 1:1, tert-butanol as the solvent, molar ratio of hydrogen peroxide to CPE 2:1, reaction time 4h, reaction temperature 35℃.
There are some advantages of the process such as mild reactive conditions, wide variety of sources of raw materials, high product yield and so on.
