为了验证间隙模型的合理性与仿真计算的可靠性 ,研制了含间隙三球销副的曲柄滑块实验装置 ,采用电涡流传感器、加速度计等对各种转速和不同间隙下的驱动力矩、附加位移、振动加速度等进行了测量。被测信号采用 DP16系统同步记录 ,直接编程处理。结果表明 ,实验结果与理论计算具有较好的一致性。另外 ,对可能影响实验结果的各种误差进行了分析。这些结果有利于进一步修正理论模型 ,并从实验角度更深入分析间隙对机构的动态作用 In order to verify the rationality of the clearance model and the reliability of the simulation calculation, a crank-slider experimental device with a clearance tripod pin pair was developed. The driving torque at various speeds and different clearances, such as the eddy current sensor and accelerometer, Displacement, vibration acceleration, etc. were measured. The measured signal using DP16 system synchronization records, direct programming. The results show that the experimental results are in good agreement with the theoretical calculation. In addition, various errors that may affect the experimental results were analyzed. These results are conducive to further revision of the theoretical model, and from a experimental perspective more in-depth analysis of the gap mechanism of the dynamic role
