Two methods for parameters optimization of traditional passive suspension based on the invariant point theory are presented in this paper. Firstly, the two degree-of-freedom dynamical model for a quarter vehicle suspension is established. Then all the invariant points for the acceleration of INTERNATIONAL JOURNAL ON SMART SENSING AND INTELLIGENT SYSTEMS VOL. 6, NO. 5, DECEMBER 2013

in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...

Transmission of vibrations into the cabin while driving and general comfort driver is essential for agricultural heavy-duty vehicles. Due to long working hours rough terrain during operation, reduced attention or health problems may occur when significant are transferred from vehicle chassis driver. One modern damping systems which can drastically minimise vibration transmission semi-active sus...

Due to the lack of body stability emergency rescue vehicles, their attitude is insufficient and they are unable realize working while driving, resulting in low efficiency. Aiming at water tower fire truck, which equipped with an active suspension system, vehicle studied. First, combined system spray a 13-DOF integrated dynamic model for truck established. Using model-assisted disturbance reject...

Active suspension provides better vehicle control and safety on the road with optimal driving comfort compared to passive suspension. Achieving this requires a good system that can adapt any environment. This article uses deep reinforcement learning method develop an neural network meets requirements according ISO 2631-5 standards. The algorithm trains agent without prior knowledge of Various s...

The paper has describes the complete design and investigation processes of permanent magnetic bearing. The passive magnetic bearing (PMB) rotor suspension rig employing no active control components was calculated, designed, constructed and tested. In order to increase the radial passive magnetic bearing stiffness, the Halbach-array configuration was used. The main purpose of the work was develo...

We demonstrate with experiments and numerical simulations that the structure and dynamics of a suspension of passive particles is strongly altered by adding a very small (<1%) number of active particles. With increasing passive particle density, we observe first the formation of dynamic clusters comprised of passive particles being surrounded by active particles, then the merging and compressio...

The purpose of this paper is to present a robust strategy in controlling a hydraulically actuated active suspension system. The controller consists of the two controller loops namely inner loop controller for force tracking control of the hydraulic actuator and outer loop controller to reject the effects of road induced disturbances. The outer loop controller utilized a proportional integral sl...

Thispaper presents a new nonlinear controller design method for regional pole placement of uncertain discretetime systems. The constraint of control input saturation is considered in the design. A sufficient condition is derived for the robust stabilization and the desireddynamic performance represented by the settling time and damping ratio.The design is formulated in terms of linear matrix in...
