The design of sports equipment should be focused on the science of materials, mechanical design and mechanics principle to carry out, the new fiber materials science can play a key role in the development of sports equipment.
The reinforced composite fiber material has more advantages over the other materials, the advantages are as follows: Lightness.
At the same time, the composite fiber materials is also the main raw material of sports equipment because of its better mechanical properties.
Application of new Fiber Materials to the Sports Equipment New fiber materials has been applied widely to the sports equipment from bicycle, boat, basketball, to golf clubs and some other sports equipments.

Therefore, the remaining life prediction under fluctuating wind has an important engineering significance for improving the security level of the transmission line towers during the service period.[3][4] In this paper the multi-scale model is selected to simulate the transmission tower in different force conditions .The rain flow counting method is chosen in the statistical analysis of cycle stress amplitude distribution, and the Miner fatigue cumulative damage theory and linear S-N curve are applied to the analysis and prediction of materials remaining useful life of the transmission tower.
An one-year, the number of cycles of stress amplitude under the direction of the wind at 90 degrees m/s average wind speed role, then a 90-degree wind direction in the next m/s average wind speed of action arising from a stress amplitude levels damage accumulation is: Fig.6 Stress time-history curve Whereby the life of the rod member or checking parts T=1/Dyear Tab.2 Fatigue life of transmission tower under wind load Rod number extent of damage Life useful lives Remaining life 1328 0.014439 69.257 1 68.257 1330 0.013329 75.024 1 74.024 1332 0.011890 84.104 1 83.104 1334 0.011105 90.050 1 89.050 1336 0.008089 123.62 1 122.62 Summary In this paper, the fatigue life of a 500 kV transmission tower is solved on the background of cumulative damage theory, based on S-N curve and Miner linear fatigue of materials.
