Abstract Resume

Background:
The concept of a new hurdle frame aiming at solving the problems of "fear Bar" and "fell bar" in hurdle training and hurdle competition was proposed in the paper, which focused on exploring the
maximum safety, fairness and convenience methods in hurdle process and achieving the innovation and upgrading of hurdle equipments.

Methods:
The experiments of implement competition safety design hurdle frame are based on the designed test of a buffer resistant spring, the base elevation arc, baffle switch button and other components to
validate the feasibility of the buffer and utilized designed to test and then to improve the sliding uplift such as the overall design of the rolling test.

Results:
By extending the time of hitting the bar, the methods were proved to help the athletes buffer the hit bar impulse and decrease the impulse and they have more time to react in hurdle process and then
to control body posture or movement adjustment; meanwhile, through the spring of elastic resistance and baffle authorities suction, the frame provided the range of resistance in 3.6-4.0 kg which is
consistent with the relevant provisions of the IAAF. Through base lifting device it is designed to ensure the vertical distance from the top of the column board to the ground remain the same in the
process of hurdles. The design of automatic reset and the bar rolling buffer type base gives full consideration to the convenience and the production cost.

Conclusions:
The competition type safety hurdle frame can effectively improve the safety of hurdles aircraft and take into account the fairness and convenience, which are also in accordance with "Athletics
Competition Rules (2014-2015)" requirements applicable to competitions and training and it will be the major changes to achieve hurdle equipments project in the future.
