Research of Cab Vibratory Response Using Multi Correlated Subsystem-excitations System Modeling
A subsystem-excitation/single-response system model is proposed, after that, the correlation between excitations is analyzed which in two subsystemexcitations /single-response system, and the excitation relationship after average process is given. On this basis, the correlation between excitations is derived which in multi correlated subsystem-excitations/single-response system and the model after average process is proposed. To address the cab vibratory response in multi correlated subsystem-excitations system, the impact of the response in various relevant cases of excitation of subsystem-excitations is analyzed, and according to coherence analysis, the method to know the contribution of excitations to the response is obtained. Finally, the results of vibration test data are given, which is measured in a vertical plane of an automobile front and rear axes; the usefulness of the theoretical analysis is verified. Theoretical analysis and experiment are valuable reference for the same engineering problems.
