Summary: In this study, the 10-7, 10-5, and 8-7 multi-level parabolic steel leaf spring systems were analyzed using ANSYS Workbench 18.1 software. The simulation results showed that the 8-7 leaf spring system had the highest deformations at all pressure values. Additionally, modal analysis revealed that the resonance frequencies for the 10-7, 10-5, and 8-7 leaf spring systems occurred within the intervals of [143.17 Hz, 520.89 Hz], [143.98 Hz, 511.4 Hz], and [146.58 Hz, 525.21 Hz] respectively.

Summary: The study investigated the vibration suppression and parametric design of a pitch-resistant hydraulically interconnected suspension system for a tri-axle straight truck, aiming to achieve smaller body vibration and tire dynamic load. By tuning the cylinder surface area, accumulator pressure, and damper valve's pressure loss coefficient, using a parametric design technique and modal analysis method, the proposed system significantly inhibits both body and tire vibrations with decreased suspension deformation.

Summary: The design and experimental validation stages of an independent front suspension (IFS) for truck tractors of articulated commercial vehicles are summarized. The suspension geometry is obtained using Multibody Systems and Design of Experiments approaches to satisfy the required conditions during wheel travel. Kinetic analysis is performed to determine the critical design loads, and mechanical design of the suspension system elements is carried out. Finite Element Analysis is applied to identify stress concentrated regions on crucial system elements and improvements are suggested. Prototyping and fatigue tests show that the final suspension is 31% lighter than an equivalent rigid front axle, with no failures encountered during bench tests.

Summary: This study investigates the reduction of Primary Yaw Stiffness (PYS) in railway vehicles by integrating inertance into the primary lateral suspensions to improve track friendliness without sacrificing passenger comfort. Systematic optimizations identified several beneficial configurations that can reduce PYS by up to 47% compared to default vehicles, potentially saving 26% in Network Rail Variable Usage Charges, while maintaining RMS carbody lateral accelerations stable.

Summary: The stiffness optimization of the transverse leaf spring suspension can be achieved by adjusting the distance between the two central installation positions of the leaf spring, which can avoid changing the structure of the leaf spring, reduce the difficulty of product development, and shorten the product development cycle, making it highly valuable in engineering applications.

Summary: Axles with leaf spring suspension systems are still popular in commercial vehicles, despite not perfectly conforming to standard multibody vehicle models. The five-link model, which includes a quasi-static solution of leaf spring compliance, offers a practical and relatively accurate solution.

Summary: The study focuses on improving visibility for snowplow truck operators during heavy snowplowing and on finding ways to prevent engine overheating caused by snow blocking radiator airflow. Through computational fluid dynamics and discrete phase modeling, a moldboard overplow deflector was designed, manufactured, and tested in the field, showing significant reductions in snow accumulation on the engine grille and truck windshield.

Summary: This study focused on the cyclic flexural strength and time dependent creep behavior of E-glass/epoxy-based composite leaf springs with different textile structures. It was found that 3D woven orthogonal structures exhibited improved performance, with the 3S1B stuffer-binder combination showing the highest initial flexural strength.

Summary: This article addresses the security control and valve opening management problem for a non-linear hysteretic leaf spring hydro-suspension system under false injected deception attack. It proposes a new control strategy using a derived Takagi-Sugeno fuzzy model and dynamic output feedback control to suppress body and tire vibrations. By dynamically regulating the servo valve openings to track the target force, it improves ride performance and reduces tire dynamic loads.

Summary: The study found that the strength of leaf springs is influenced by fabric and the assumption of transverse isotropy is invalid. The measured transverse tensile strength is lower in the out-of-plane direction, potentially reducing resistance against delamination.

Summary: Selecting the appropriate tyre configuration and settings is important for minimizing soil compaction and power loss, and optimizing traction. This study investigated the effect of different tyre configurations, sizes, and inflation pressures on soil strength and rolling resistance. The results showed that heavier tractors had greater power loss in rolling resistance, and rut depth was directly related to tyre inflation pressure.
