High energy storage high-torque test-bed is an important testing equipment for a large energy absorption device performance testing and reliability testing.The energy-absorbing flywheel and the cone friction clutch are the key components of the test-bed.The test-bed can verify the maximum working capacity of several concatenated energy-absorbing devices,and find out the operating characteristics of concatenated energy-absorbing devices in the conditions of high transient torque,and test the reliability.Because of the huge energy storage and transferring torque energy,it brings a series of problems to the design and use.This paper presents a detailed analy si s of the functional requirements of the test-bed,and comes up with a feasible solution,and verifies it through finite element software simulation and analysis.This paper introduces the working characteristics of high energy storage high-torque test-bed and the development status at home and abroad for its key components energy storage flywheel and clutch.According to the test-bed working characteristics and performance requirements,it determines the overall program of the test-bed.Taking full account of the working environment and application conditions of the test-bed,it selects appropriate materials,and designs the key components of the test-bed reasonably,then completes solution research.Through researching the flywheel structure,the paper gives a new structure of the flywheel.By replacing the detachable inertia ring in the rim,it makes rotary inertia of the energy storage flywheel variable.Aimed at abrasive dust exhaust and air convection cooling while the friction clutch working,it gives the slotting and reaming structural form of the cone friction clutch.The paper makes the related static analysis of the flywheel and clutch with ANSYS software,and then verifies the design reasonable.In the process of cone friction clutch engagement,the driving disk and the driven disk slide relatively,and generate a lot of friction thermal.It will lead to sharp temperature increase in friction disk,and the thermal stress is likely to cause damage to the clutch.Therefore,it is necessary to makes analysis of transient temperature and thermal stress through the clutch friction and thermal generation,and then verifies the clutch design reasonable.This paper sets up a three-di mensional finite element model of the friction clutch,and thermal flux mathematical model.With reasonable set of density of therm al flux boundary condition,it makes thermal-structural coupling analysis of clut ch friction pair using ANSYS finite element software,and obtains three-dimensional temperature field of clutch friction disc.It obtains the therm al deformation and thermal stress fields by se quential coupling method,and makes analysis and study of distribution oftemperature increment and thermal stress.
