Problems solved by technology

However, since the skyhook inertia can only simulate the full-load mass, the skyhook inertia coefficient cannot be adjusted in real time according to the body movement conditions, and cannot effectively adapt to the body movement conditions

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing and example.

[0031] An ideal ceiling system based on mechanical memory elements, including ideal ceiling memory inertia capacity, ideal ceiling memory damping and ideal ceiling memory spring system respectively.

[0032] Such as figure 2 As shown, the ideal skyhook memory-inertia system includes inertial container (1), sprung mass (2), spring (3), shock absorber (4), unsprung mass (5) and tire equivalent spring (6 ). The spring (3) and shock absorber (4) are arranged between the sprung mass (2) and the unsprung mass (5), and the inertial container (1) is arranged on the inertial reference frame and the sprung mass (2) between. The inertial container (1) produces an inertial force opposite to the acceleration of the sprung mass. Ceiling memory inertia can adaptively offset part of the acceleration of the sprung mass according to the movement of the vehicle body, thereby ...

Abstract

The invention relates to an ideal ceiling system based on a mechanical memory element and a semi-active suspension system of the ideal ceiling system. The ideal ceiling system comprises an ideal ceiling memory inerter system, an ideal ceiling memory damping system and an ideal ceiling memory spring system. The ceiling semi-active suspension system comprises a ceiling memristor-inerter semi-active suspension system, a ceiling memristor-damping semi-active suspension system and a ceiling memristor-spring semi-active suspension system; according to the invention, a ceiling memory inerter system, a ceiling memory damping system and a ceiling memory spring system are respectively realized through the continuous adjustable inerter device, the continuous adjustable damping device and the continuous adjustable rigidity device. Memory element coefficients (a memory inerter coefficient, a memory damping coefficient and a memory spring stiffness) dynamically change along with the change of sprung mass motion conditions, and the change rule can be equivalent to a semi-active control strategy related to Dmx, so that the control effect of the ceiling memory element semi-active suspension system is equivalent to that of a ceiling semi-active suspension system with an adjustable coefficient; and the load and road condition adaptability is improved.

Description

technical field [0001] The invention relates to an ideal ceiling system based on mechanical memory elements and a semi-active suspension system thereof, belonging to the technical field of vehicle suspension vibration control. [0002] technical background [0003] The memory element was first proposed and developed in electricity, and according to the electromechanical similarity theory, there is also a memory element in the mechanical element. The criterion for judging an element as a memory element is: there is only a single value in a certain plane of the element The algebraic relationship (that is, the constitutive relationship of the components), and the dynamic corresponding relationship between the variables in the other planes, and the relationship curve between the variables is a "twisted hysteresis loop". In the paper "The missing mem-inerter and extended mem-dashpot found", there is a detailed description of the mechanical memory element, and it is pointed out tha...
