Basing on the finite element and nonlinear finite element,the car collision was analyzed in this paper.The effect of the approaching speed on the collision deceleration of the car was studied by chang
Human error has been recognized as the major cause for industrial accidents.Because of the changing role of human in modern manufacturing environment and the lack of understanding of the human cost,th
Basing on the stiffness model of the plate and thin shell by using the finite element formed,the basic method of establishing the car structure finite element models was studied in this paper.The proc
A lock-in amplifying technique finds its use in the online determination of gasses in low concentrations against extremely strong background noise,however a more stable reference frequency signal is m
Based on the theory of multivariate statistical analysis,this paper applies strictly factor analysis and cluster analysis methods in the evaluation of urban air quality,by calculating the component sc
The text from three aspects—a brief summary of the development of Human-Computer Interaction describes of the Human-Computer Interaction is an interaction between people and a machine with a computer,
This paper constructs the feedback loop about the cause-effect relation on accidents by using the research method for System Dynamics and analyzing the influencing factors of the safety accidents happ
