介绍了履带推土机动态性能试验研究中的有关试验工况和试验方案，提出了在进行数据处理时对频率成分未知的时间历程信号采用傅立叶逆变换法来检验采样频率正确性的观点。
This paper introduces the relevant test conditions and test schemes in the dynamic performance test research of crawler bulldozers and puts forward the viewpoint of using the inverse Fourier transform to test the correctness of the sampling frequency in the time history signal of unknown frequency components during data processing.
