随着现代汽车发动机转速的不断提高，对离合器也提出了新的要求，除了要求它在高速下仍能保证传递发动机的最大扭矩外，还要求其必须具有足够的旋转机械强度，以保证安全可靠的工作。离合器在工作过程中与变速器飞轮相连，其结构构成比较复杂，零件极易在高速旋转过程中在离心力的作用下，产生破坏，因此开发其具有破坏性的性能试验台，检验其承受高速运转的能力，避免其在使用过程中出现事故是十分必要的。
设计过程中，针对整个试验台的性能要求对整个试验台进行布置设计，包括电机的选择，传动比的分配，联轴器的选择等。另外，还对对变速器中的齿轮，轴，键进行设计计算以及强度等的校核计算，完成了离合器压盘总成高速破坏试验台的设计。为研制开发汽车零部件试验装置提供理论参考。

ABSTRACT

With he Hyundai Motor and continuous improvement in engine speed, the clutch also made new demands, in addition to the requirements despite its high-speed engines to ensure maximum torque transmission, but also require the rotation must have sufficient mechanical strength to ensure safety reliable work. In the course of clutch and transmission flywheel connected to the structure constitutes a complex, vulnerable parts in the high-speed rotation in the course of the effect of centrifugal force, resulting in damage, so the development of its devastating performance test rig, to test its high-speed operation under the the ability to avoid its use in case of accidents is very necessary.
The design process, the test-bed for the entire performance requirements of the test-bed for the entire layout, including the choice of motor, the transmission ratio of the distribution, the choice of coupling. In addition, in the right right reducer gears, shaft, key design and strength calculation of the check, the completion of the clutch pressure plate and cover assembly of high-speed destruction of test-bed design. Research and development of automotive components for test equipment and provide a theoretical reference.

Key words: Clutch Assembly; Transmission; Reducer; High-speed Destructive Test; Test-bed Design
