采煤机用变频器振动和冲击试验夹具设计与研究

Research and Design of Converter Vibration and Impact Test Clamp for Coal Mining Machine

针对采煤机用变频器承受振动加速度5 gn和冲击加速度50 gn的目标,在满足最大振动力和冲击力的基础上,运用三维软件设计符合标准试验台使用的夹具体,依据振动试验和冲击试验技术要求,对结构焊接强度和螺钉抗拉强度进行校核,为矿用机载设备振动和冲击试验提供一套夹具设计技术方案。

In view of the coal mining machine＇s inverter under the goal of vibration acceleration 5 gn and shock acceleration 50 gn, to meet the maximum vibration force and the impact force, design standard test bench lamp to use 3D software design, according to the requirement of vibration test and shock test, the weld strength and the screw＇s extension strength are checked, provide a set of clamp design scheme for mine airborne equipment vibration and shock testing.
