Vehicle Suspension System

The performance index of a suspension system is a function of the maximum and minimum values over the parameter interval. Thus metamodel-based techniques can be used for designing suspension system hardpoints locations. In this study, an adaptive metamodel-based optimization approach is used to find the proper locations of the hardpoints, with the objectives considering the kinematic performance of the suspension. The adaptive optimization method helps to find the optimum locations of the hardpoints efficiently as it may be unachievable through manually adjusting. For each iteration in the process of adaptive optimization, prediction uncertainty is considered and the multiobjective optimization method is applied to optimize all the performance indexes simultaneously. It is shown that the proposed optimization method is effective while being applied in the kinematic performance optimization of a McPherson suspension system.

The Impact

This article concerns a hybrid vehicle suspension system that can regenerate energy from vibrations. To further improve the performance of the hybrid vehicle suspension system, the design of the energy-regenerative circuit is investigated. First, the force tests of the linear motor used in the hybrid vehicle suspension were carried out, and the key parameters of the linear motor were obtained. Then, the selection procedures of the protective resistance, inductance, and initial terminal voltage of the super capacitor were discussed. These aforementioned parameters’ values were determined by considering the impact of the hybrid suspension on the dynamic performance indexes and the energy-regenerative efficiency. Simulations showed that, in comparison to the original hybrid suspension system, the designed hybrid suspension effectively improved the energy-regenerative efficiency, and that the dynamic performance indexes of the suspension were synchronously improved. Given the result of the simulation analysis, which were validated by bench tests, it is shown that the optimized energy-regenerative circuit presents an enhanced regeneration efficiency, with an improvement of nearly 13% compared to the original suspension system.

Vehicle Suspension System

In automobiles, a double wishbone suspension is an independent suspension design using two wishbone-shaped arms to support the wheel and the maximum load is transferred from upper wishbone arm to the lower arm which may cause failure and bending of lower wishbone arm. The developed lower control arm consists of three holes at one end, which are fixed to the wheel hub and other end is connected with chassis which is placed in between the steering link. In this study, topology optimization approach is presented to create a new design of a lower control arm.

Abstract The paper presents a procedure for the integrated design (tuning) of tyres and suspensions of racing cars. A complete model of a racing car has been developed and implemented. The model is suitable to simulate the vehicle behaviour in extreme driving conditions. A number of ground tests have been performed to validate the vehicle model, with fully satisfactory results. Many different driving situations (steady state, J-turn, lane-change, power-on/off while steering, braking on a bend, passing over a kerb while steering) have been considered. By means of a Multi-criteria approach many performance indexes have been optimised by changing the parameters related both to the vehicle suspension system and to the tyre characteristics. A global-approximation model has been built (the original physical model has been substituted by another purely numerical model), allowing fast optimisations. A number of preferred solutions have been selected from the optimal set. Professional drivers tested the cars fitted with optimal suspension/tyre settings. The improvements predicted by computations were substantially confirmed. The adopted procedure has proved to be reliable and effective both for obtaining the highest performances and for reducing the number of ground tests.

Suspension Structure

Background: Vehicles generally travel on different road conditions, and withstand strong shock and vibration. In order to reduce or isolate the strong shock and vibration, it is necessary to propose and develop a high-performance vehicle suspension system. Objective: This study aims to report a pneumatic artificial muscle bionic kangaroo leg suspension to improve the comfort performance of vehicle suspension system. Methods: In summarizing the existing vehicle suspension systems and analyzing their advantages and disadvantages, this paper introduces a new patent of vehicle suspension system based on the excellent damping and buffering performance of kangaroo leg, A Pneumatic Artificial Muscle Bionic Kangaroo Leg Suspension. According to the biomimetic principle, the pneumatic artificial muscles bionic kangaroo leg suspension with equal bone ratio is constructed on the basis of the kangaroo leg crural index, and two working modes (passive and active modes) are designed for the suspension. Moreover, the working principle of the suspension system is introduced, and the rod system equations for the suspension structure are built up. The characteristic simulation model of this bionic suspension is established in Adams, and the vertical performance is analysed. Results: It is found that the largest deformation happens in the bionic heel spring and the largest angle change occurs in the bionic ankle joint under impulse road excitation, which is similar to the dynamic characteristics of kangaroo leg. Furthermore, the dynamic displacement and the acceleration of the vehicle body are both sharply reduced. Conclusion: The simulation results show that the comfort performance of this bionic suspension is excellent under the impulse road excitation, which indicates the bionic suspension structure is feasible and reasonable to be applied to vehicle suspensions.
