Shock absorbing system with combined rigidity and damping adjusting function and shock absorbing method

Abstract

The invention discloses a shock absorbing system with a combined rigidity and damping adjusting function and a shock absorbing method. An air spring with an additional air chamber and a magnetorheological shock absorber which are connected in parallel are arranged between an upper connecting plate of a suspension frame and a bottom plate of the suspension frame; and the air spring is connected with the additional air chamber via a positioning control valve. The shock absorbing method comprises the following steps that a controller performs Fourier transformation on automobile body response acceleration time domain signals at a specified time interval, and outputs control signals to the positioning control valve according to the biggest excitation frequency of vertical energy, the opening of an orifice between the air spring and the additional air chamber is controlled and adjusted in real time, so that the rigidity of the suspension frame is changed, the purpose of avoiding the excitation frequency is achieved, the damping of the suspension frame is adjusted by changing input current of the magnetorheological shock absorber, and shock is attenuated further. The combined rigidity and damping adjusting function can be realized, an adjusting range is expanded, the shock absorbing system adapts to complex and changeable running work conditions of automobiles, and the shock absorbing property is increased.

AI Technical Summary

Benefits of technology

This patented technology allows an anti-vibrating device (called a magnetic bearing) called a stabilizer to reduce vibratory motion caused when vehicles travel over uneven surfaces without causing damage. It uses feedback from sensors placed near each wheel's axis to determine if there are any problems beforehand. By doing this, it improves overall road safety through reducing noise levels and prevention against tire wear issues. Additionally, the use of a special type of liquid crystal material called ferroelectric liquid crystals helps dissipate excess power during operation. Overall, these technical features enhances the functionality and efficiency of the anti-Vibration device.

Problems solved by technology

This patented technical problem addressed by this patents relates to finding an effective way to reduce unwanted vibrations during car travel without causing any negative effects on passengers or other people's body.
