摘要:
设计了一种可以模拟实车工作状态的疲劳试验机，能较真实地获取空气弹簧使用寿命。由几何关系和曲柄连杆运动原理，推导得到所要求振幅的曲柄半径范围值，由最小二乘法确定最佳的曲柄半径值。采用仿真和试验相结合的方法，得到驱动悬梁所需的可能最大力，结果显示对称安装2个较单个安装最大力从36 000 N降至9 000 N以下，节能效果显著；用ADAMS软件模拟悬梁的运动状况，获取夹具中心点的运动速度曲线；计算得到悬梁所需的输入功率为4.13 kW，结合系统传动效率和电机功率因数，确定电机功率，完成电机选型。
Abstract:
A fatigue testing machine is designed in this paper, to acquire relatively real longevity of air spring by simulating the working state of real vehicles. The crank radius range under the condition of amplitude is deduced by the geometric relationship and crank-rod mechanism, and the optimal value of crank radius is determined by using the least square method. The maximal force required to drive the beam is obtained by the combination of the simulation and experiment. The test result shows a reduction from 36 000 N to less than 9 000 N by choosing to install two symmetrically instead of install one. The ADAMS software is used to simulate the movement condition of a cantilever and the speed curve of the center of clamp. The input power of the cantilever is calculated at 4.13 kW. Considering the transmission efficiency of the system and the power factor of the motor, the motor power is determined and the motor is selected.
