“…The vibration of any frequency when transferred to the human body, it is called whole-body vibration (WBV) [73]. This may be the seat of the driver, moving trains' platform, a power tool or one of several other components [74,75]. This vibration is known to cause a variety of physiological problems, including musculoskeletal, circulatory, and nervous, both acute and chronic injury, and low back pain [68,69,72,76,77].…”

Electric vehicles (EVs) are promising solutions to the problems faced by combustion engine-propelled automobiles. The futuristic transportation system would be majorly catered by battery EVs, hybrid EVs, and fuel cell EVs with a different combination of energy sources that could successfully meet the requirements of different categories of vehicle propulsion systems. However, to execute such vehicle systems with a high level of safety and comfort for the transportation of people and products, a few difficulties must be resolved. EVs of today face problems such as noise-vibration-harshness, energy storage difficulties, torque fluctuation/ripple in the power train, inadequate range, and some others. The present review paper comprehends major noise and vibration issues existing in EVs and attempts made by the researchers to find solutions to such problems. The major problem faced by the vehicle as well as by the passengers is vibration and discomfort. These vibrations if continued for a longer period might cause severe damages to the vehicle structure as well as to the passenger’s body. These issues must be thoroughly addressed by researchers to increase ride comfort, which is a crucial requirement of the hour as well.

The focus of this work is to investigate the ticking noise produced by the vibro-impacts between piston pin and connecting rod small head bearing. Numerical calculation and experimental verification methods were adopted and a novel method to control this intermittent noise was proposed. The dynamic model of crankshaft connecting rod piston with full floating piston pin was established and the essence of piston pin ticking was analyzed. The occurrence time of the ticking corresponded to the crankshaft angle when the resultant force of piston pin passed through the 0 axis. At the moment of impact, the peak hydraulic pressure of lubricating oil was found to be proportional to the impact strength. In order to suppress this noise, the oil groove on the bearing was designed considering the minimum oil film. After adding the oil groove, the impact intensity was significantly reduced and the noise was even eliminated. The calculated results were in good agreement with the experimental tests, and the research of this work provided a reference for controlling the ticking noise of piston pin.

“…8 The magnetorheological damper is widely used in semi-active suspension systems due to its simple structure, fast response, high dynamic range, and low power cost. 9,10 Active control forces are generated directly by hydraulic or electromagnetic actuators. 11 Compared with semi-active control, active control has stronger adaptability.…”

The transverse leaf spring (TLS) suspensions are a promising option for van vehicles due to their high load-carrying capacity and excellent handling stability. However, its ride comfort remains a major challenge. This paper investigates and compares the effects of semi-active and active control strategies to enhance the ride comfort of TLS suspensions. Firstly, a four-degree-of-freedom (4-DOF) half-car model and a multi-body dynamics (MBD) model of the TLS suspensions are established. The MBD model has higher accuracy and can describe the medium and high frequency characteristics of the TLS suspensions, such as the suspension offset frequency and the frequency response function of the body vertical acceleration (BVA). Therefore, based on the MBD half-car model with TLS suspensions, this paper proposes an optimal fuzzy PID active control strategy considering the left and right suspension coupling. The optimization objectives are the BVA, the left and right suspensions dynamic deflection, and the left and right wheels dynamic displacement. The integral absolute error is used as the evaluation criterion. The left and right fuzzy PID controllers’ parameters are obtained through particle swarm optimization. Simulation results demonstrate that the particle swarm optimization fuzzy PID active control strategy effectively controls the low-frequency vibration of the TLS suspensions and suppresses the medium- and high-frequency vibration characteristics compared with the traditional skyhook semi-active control strategy. This technology provides a reference for improving the ride comfort of the TLS suspensions.
