Several Cases When the Dynamic Equation of the Parallel Six-axis Acceleration Sensing Mechanism Fails
The cause of the failure of the dynamic equation of the sensing mechanism is not clear.Taking three typical cases of the loss of the dynamic equation of the sensing mechanism as an example,the mechanism of the failure of the dynamic equation of the mechanism is revealed by analyzing the causes of the failure of the dynamic equation in each case.Firstly,by calculating the rank of the Jacobian matrix of the mechanism,a reason for the failure of the dy-namic equation is excavated,and the dynamic equation is successfully deduced when the singularity occurs.Secondly,the working frequency of the mechanism and the fundamental frequency of the mechanism are analyzed.Combined with specific examples,another case of failure of the dynamic equation is obtained.Thirdly,the real-time performance of the dynamic equation when the branch chain of the mechanism fails is analyzed,and the third case of the failure of the dynamic equation is summarized.Finally,the virtual prototype experiment is carried out.The results show that the three reasons for the failure of the dynamic equation proposed in this paper are true and reliable.
