Abstract

The invention discloses an inerter-spring-damper (ISD) suspension system for a sliding block connecting rod type inerter with a variable inerter coefficient. The ISD suspension system comprises a spring, a damper and the inerter. The upper end after the spring, the damper and the inerter are connected in parallel is connected with sprung mass, and the lower end after the spring, the damper and theinerter are connected in parallel is connected with unsprung mass. The lower end of the unsprung mass is connected with pavement excitation through a tire equivalent spring. The inerter is mounted ona flywheel shaft in a matched mode through a flywheel. One end of a sliding block connecting rod is connected with the edge of the flywheel in a hinged mode, and the other end of the sliding block connecting rod is connected with the flywheel shaft in a hinged mode. A sliding block is mounted on the sliding block connecting rod in a sleeving mode and connected with a guiding rod through a hinge.The guiding rod is located in a guiding groove in a flywheel chamber. The guiding rod only makes vertical direction motion and simultaneously drives the sliding block to slide smoothly on the slidingblock connecting rod. The rotating range of the sliding block connecting rod in the sliding block connecting rod type inerter is only in the half side where the guiding rod is located, the overall mass of the inerter can be effectively decreased, and thus the inerter coefficient of the inerter is variable in the working process.

Description

technical field [0001] The invention belongs to the field of vehicle suspension, and in particular relates to an ISD suspension system comprising a sliding block link type inerter with a variable inertia coefficient. Background technique [0002] Mechatronics is an important development direction in the field of engineering today. There is a corresponding relationship between mechanical and electronic systems, one of which is the "force flow-current" correspondence, that is, the mass, damper, and spring in the mechanical system correspond to the capacitance, resistance, and inductance in the electronic system, respectively. The components in the electronic system have two free endpoints, but in the corresponding mechanical system, the mass component is only a single-terminal component, which cannot strictly correspond to the capacitance, which greatly limits the application and development of the mechatronics theory. [0003] Cambridge University scholar SMITH invented the ...
