Title Design of high speed friction coefficient measuring device for metal materials

Abstract In order to obtain the friction coefficient of metal under high speed and high pressure，a high speed friction coefficient measuring device is designed. Based on the analysis of the design requirements and application background of the high speed friction measuring device, a method for measuring the high speed friction coefficient by measuring the normal force and tangential force at the same time is proposed.The working principle and structure of the high speed friction measuring device are introduced, and the structural parameters and processing materials of the friction measuring device were determined,analysis and design of sensor，the sticking position of strain gauge is analyzed.And then use Solidworks 3D modeling , then use workbench of the ANSYS to simulation analysis for the measurement devices .

Simulation analysis shows that, In the case of ultimate load, the stress and strain of the dangerous section of the measuring device are all in the range of theoretical calculation. Deformation of the device is in the normal elastic range,they satisfy the design requirements . It can be provided for the design of high speed friction coefficient measuring device to refer .
