摘要
根据三支点平台支撑反力法测量原理建立了小型作业机质心测量系统。采用ADAMS建立了质心测量平台的动力学模型;基于Matlab建立了测量系统的理论仿真控制模型,并在理论仿真模型中引入压力传感器测量时和升降推杆移动时产生的随机误差,建立了小型作业机质心测量系统的仿真控制模型。通过ADAMS与Matlab的联合仿真,验证了所建系统理论模型的正确性,并得到了测量平台的倾斜角度与测量误差的相对关系,对后续的提高质心测量系统测试精度和测试效率的控制策略研究和实践具有十分重要的理论和工程意义。
A small agricultural machinery centroid measurement system was established based on three-point platform supporting reaction method theory. At the same time, the multi-body dynamics model of centroid measurement system was established using ADAMS and theory simulation models of the measurement system was also established based on Matlab. Then the random error caused by the pressure sensor and displacement of lifts putter when putting up and down in real control system was introduced in the simulation model Finally, the simulation model of small agricultural machinery centroid measurement system was established The correctness of the model was verified and the relevant relationship between gradient angle and measurement error of measuring platform was also obtained through a collaborative simulation by ADAMS and Matlab. The results have an important theoretical and application significance on future control strategy research and practice on increasing the test accuracy and efficiency.
