“…1. Moreover, jounce bumpers are commonly manufactured from hyperelastic materials like rubber or Polyurethane (PU), and they primarily serve to absorb impact energy and improve Noise, Vibration and Harshness (NVH) performance by preventing suspension components from being fully compressed during transient impacts caused by heavy loads, potholes, curbs or objects on the road [1]. Moreover, jounce bumpers may also act as an assistant compression spring when the maximum load is approached [2].…”

“…16 It is an effective way to improve the handling performance of the in-wheel motor drive electric vehicle by considering the actual structural parameters of the front and rear suspensions and taking the typical test evaluation indexes of handling stability as objective. 17,18 The paper presents a test prototype of a small inwheel motor drive electric vehicle based on an A0 car. The car is composed of a double pivot front suspension system that is more suitable for matching the in-wheel motor drive system, a double wishbone rear suspension system, and an active steering system.…”

In-wheel motor drive electric vehicle has superior dynamic control capability, but the inner space of wheel hubs that are originally used to install the suspensions is occupied by wheel motors, which leads to an increase in unspring mass and a structural change in suspensions. By referring to a standard car’s suspension to design the suspensions of an in-wheel motor drive electric vehicle, the required vehicle handling stability is hard to reach, so the structure of the suspensions must be redesigned and optimized to facilitate the next step of vehicle dynamics control. In this paper, the virtual prototype is established based on a self-developed in-wheel motor drive electric vehicle, and the correctness of the model is validated by field tests. Then, the design of experiment method is used to analyze the impact of the structural parameters of the front double pivot suspensions and the rear double wishbone suspensions; the sensitivity of the suspension parameters is obtained by entropy measurement, and the suspension parameters with great influence on the handling stability are selected as the design variables and optimized by Non-dominated Sorting Genetic Algorithm II. Through the optimization, the maximum lateral acceleration and the maximum roll angle can be reduced by 4.8% and 10.3%, respectively, under the double lane change test and reduced by 12.7% and 7.9%, respectively, under the serpentine test. The maximum speeds under double lane change and serpentine test simulations can be increased by at least 7% and 5%, respectively. The related research has guiding significance for the suspension design of the in-wheel motor drive electric vehicles.

Electric vehicles (EVs) are an alternative architecture in the automotive industry that provide reduced emissions. This research has developed a switch reluctance motor (SRM) in-wheel drivetrain for an EV. SRM drivetrains are cheaper and do not use rare earth elements unlike a permanent magnet motor (PMM). Conversely, the in-wheel SRM has a drawback of an increased mass on the suspension when compared with an equivalent power output PMM drivetrain. This situation results in an increased mass at the wheels; hence, a suspension analysis is required. This paper discusses the suspension dynamics evaluated using a quarter-car simulation of an in-wheel SRM EV and compares it to the internal combustion engine (ICE) vehicle. The simulation used step loads derived design scenarios, namely (1) sprung, (2) unsprung and (3) driver's seat. Further Bode plot analysis techniques were used to determine the ride comfort range for the developed EV.
