Significant Attention

Considering the rate of depletion of the available oil-based fuels, Renewable Energy Technologies are receiving significant attention in these years. It is, therefore, necessary to find alternatives to energy sources. This project focusses on one such alternative. A study is done on a vehicle suspension system and braking system. Suspension in vehicles produces linear vibrations due to the roughness on the roads. These vibrations are absorbed the shock absorbers and dissipated in the form of heat. In the case of a conventional braking system,a huge amount of heat is lost due to friction. This study proposes a design of a system where the heat lost in the suspension system is extracted, converted into a usable form of electrical energy and stored in batteries. This stored energy is further used in the operation of electromagnet powered brakes. Using the Regenerative Suspension System reduces the waste of energy in the shock absorbers and gives an alternative energy source and use of the Electromagnetic Braking System ensures frictionless braking. Thus, the overall consumption of energy is reduced by a notable amount.

Wasted Energy

The world is demanding for alternative way of energy consumption for vehicle usage. The energy efficient vehicle (EEV) is one of the advancement for future land transportation that known as hybrid and electric vehicles nowadays. The vehicles use different energy other than fuel which is electric energy. This paper emphasizes the development of electromagnetic energy regenerative suspension system (EReSS) as a system that harvests energy from the vibration of vehicle suspension system. The harvested energy is converted to electrical energy for vehicle usage. A prototype of electromagnetic EReSS is fabricated and laboratory experimentation on test rig is conducted to test the voltage output. It is observed that the EReSS can harvest the wasted energy from the vibration and produce sufficient electric energy for the vehicle electrical and electronic usage. The number of windings of the coil and diameter of the coil affect the voltage output of the EReSS. The voltage output of the EReSS can be optimized by setting up the parameters. As the EReSS is proven to harvest energy, it can be used on hybrid and electric vehicle to improve the efficiency of the vehicle and reduce the fuel consumption.

This paper presents an energy-regenerative suspension device that is able to harvest some of the wasted energy that is generated in a suspension system. For a traditional road vehicle suspension system, shock absorbers are mainly dissipating energy to reduce vibration. The dissipated energy may be collected to improve the fuel economy of road vehicles. In this research, CarSim and Simulink are used to simulate and determine the harvestable energy in a conventional shock absorber under different operating conditions. A conceptual energy-regenerative absorber is designed and tested using a fabricated prototype. A variable speed motor is implemented to adapt the change of stroke length of a mechanism due to the various road roughness. Instruments, e.g., laser tachometer, pressure gauge, ammeter, voltmeter, and stopwatch, are used to collect data. The simulation and prototype testing results indicate that the proposed energy-regenerative suspension device could harvest dissipated energy to improve vehicle fuel economy.

Dynamic simulation, based on modelling, has a significant role during to the process of vehicle development. It is especially important in the first design stages, when relevant parameters are to be defined. Shock absorber, as an executive part of a semi-active suspension system, is exposed to thermal loads which can lead to its damage and degradation of characteristics. Therefore, this paper attempts to analyze a conversion of mechanical work into heat energy by use of a method of dynamic simulation. The issue of heat dissipation from the shock absorber has not been taken into consideration.

Regenerative suspension systems, unlike traditional passive, semi-active or active setups, are able to convert the traditionally wasted kinetic energy into electricity. This paper discusses flexible multi-objective control design strategies based on LMI formulations to suitably trade-off between the usual road handling and ride comfort performance and the amount of energy to be harvested. An electromechanical regenerative vehicle suspension system is considered where the shock absorber of each wheel is replaced by a linear electrical motor which is actively governed. It is shown by simulations that multivariable centralized control laws designed on the basis of a full-car model of the suspension system are able to achieve larger amount of harvested energy under identical ride comfort prescriptions with respect to scalar decentralized control strategies, designed on the basis of a single quarter-car model and implemented independently on each wheel in a decentralized way. Improvements up to 40 % and 20 % of harvested energy are respectively achievable by the centralized multivariable H 2 and H ∞ optimal controllers under the same test conditions.

Suspension Performance

Semi-active suspension systems allow for adjusting the vehicle shock damping and hence improved suspension performance can be achieved over passive methods. This paper presents the design of a novel fuzzy control structure to concurrently improve ride comfort and road handling of vehicles with semi-active suspension system. A full car model with seven degrees of freedom is adopted that includes the vertical, roll, and pitch motions as well as the vertical motions of each wheel. Four decentralized fuzzy controllers are developed and applied to each individual damper in the vehicle suspension system. Mamdani’s method is applied to infer the damping coefficient output from the fuzzy controller. To evaluate the performance of the proposed controller, numerical analyses were carried out on a real road bump. Moreover, results were compared with well-known and widely used controllers such as Skyhook. It is shown that the proposed fuzzy controller is capable of achieving enhanced ride comfort and road handling over other widely used control methods.
