“…For the frequency characteristics of the vehicle under steering input, r / φ| f =0.5 mainly reflects the steering stability of the vehicle, t a y | f =0.5 mainly reflects the steering maneuverability, and ϕ / a y | f =0. 5 mainly reflects the roll resistance of the vehicle. r / φ| f =0.5 , ϕ / a y | f =0.5 , and t a y | f =0.5 should all be optimized in the direction of reduction.…”

As an important component of the steering system, steering trapezoids should be designed to satisfy multiple performances of the vehicle. In this study, theoretical and simulation analysis has been conducted focusing on the influence of the steering tie rod on the Ackermann error, bump steer, forces at the tie rod joints, and frequency characteristics of the whole vehicle. The results show that the Ackermann error is mainly influenced by the position of the outer point of the steering tie rod. The bump steer is mainly influenced by the Z coordinate of the outer point. The impact force at the joint and the frequency characteristics are mainly influenced by the X and Z coordinates of the outer point of the tie rod. The trends of the evaluation indexes for each performance to the hard point coordinates are not completely consistent and some are conflicting. To integrate the vehicle performance, multi-objective optimization is carried out with Archival Micro Genetic Algorithm, Neighborhood Cultivation Genetic Algorithm, and Non-Dominated Sorting Genetic Algorithm-II algorithms considering the hard point coordinates as variables and the evaluation indexes as optimization objectives. The optimization results show that the relative optimal solutions obtained by the three optimization algorithms provide a significant improvement to the Ackermann error, while other performance indexes have differences. In the practical application of steering trapezoid optimization, it is possible to choose the appropriate optimization algorithm based on the focus of the vehicle performance requirements.

“…In the design of a steering mechanism, it is essential to know the sensitivity of the mechanism to changes in dimensions due to manufacturing, assembly, and wear errors in the kinematic pairs; this analysis is carried out after the optimization but can also be integrated into the optimization process [12][13][14].…”

This article presents a method for the dimensional synthesis of the rack-and-pinion steering mechanism by optimization technique based on a novel synthesis equation. The proposed kinematic model allows obtaining a polynomial synthesis equation to formulate the objective function as a sum of squares. Then, the computation of the objective function derivatives is straightforward compared to existing formulations. Finally, the application of the proposed method is shown through a numerical example implemented in Matlab®.

“…The inertia force varies periodically with the crank rotation, which accelerates the crank linkage fatigue damage and excites the forced vibration of other components. The crank linkage combines reciprocating and rotating motions [1]. The inertia forces cannot be balanced inside the element, akin to a rotor rotating around a fixed axis.…”

Unbalanced inertia force is inevitably generated during the operation of crank linkage. It is one of the main excitation sources of air compressor vibration and the focus of managing air compressor vibration noise. In this regard, this paper studies the variation law of inertia force in the four-star type crank linkage mechanism. Certain balancing methods are used to reduce the unbalanced inertia force. Firstly, we present a comparison of perfect and partial balanced problems of crank linkage inertia forces. Then, using the ADAMS software multibody dynamics calculation method, the balancing mass is numerically calculated to optimize the design of the balancing mass for partial balancing of inertia force. Next, the influence law of piston mass asymmetry on the force of crankshaft revolving pair is studied. Lastly, two new types of four-star type crank linkage mechanism are proposed from the viewpoint of completely balanced inertia forces and moments of inertia. The results show that the perfectly balanced inertia force is better than the partially balanced inertia force in terms of a balancing effect. The parametric design of ADAMS software is more efficient and can get the best quality quickly. The design of perfectly balanced inertia force will increase the length and complexity of the crankshaft, while reducing the structural strength. The research results of this paper are important for improving the vibration damping performance of marine air compressors.
