“…In addition, the bushing installation angle and bushing stiffness will affect the roll stiffness and force of the suspension, which will affect the suspension C characteristics, which in turn will affect the steady-state and transient characteristics of the vehicle. (2) The relationship between the bushing installation angle and the steady-state characteristic index in the range of [290°to 90°] is discussed, that is: when the bushing installation angle is around 222.5°, the understeer characteristic of vehicle is the best, and the steady-state…”

Both the bushing installation angle and bushing stiffness of torsion beam suspension have important and complex effects on suspension characteristics and vehicle handling stability. For improving the vehicle handling stability by optimizing the two, this paper systematically analyzes the influence mechanism of the bushing installation angle and bushing stiffness of the torsion beam suspension on the suspension C characteristic. The nonlinear relationship between the bushing installation angle and the steady-state characteristics index in the local design space is discussed. The influence mechanism of the bushing installation angle and bushing stiffness on the frequency response characteristics is deeply analyzed, the variation relationship of the frequency characteristic index at the low frequency of 0.5 Hz under different bushing installation angles and bushing stiffnesses is obtained. Finally, the bushing stiffness, which has a great influence on the frequency characteristics, and the bushing installation angle are taken as the optimization variables, and the frequency characteristic index is taken as the optimization goal, and the multi-objective collaborative optimization of the frequency characteristic is carried out with the help of genetic algorithm. From the comparative analysis of transient and steady-state characteristics before and after optimization, it can be seen the vehicle handling stability has been improved.

“…In actual engineering, the finite element analysis method is frequently utilized to resolve structural mechanics issues since it may make issues simpler, and make calculations more efficient. The problem may then be roughly solved by deriving the domain's overall satisfaction requirements, which is widely considered as a highprecision engineering analysis tool and has evolved into an effective solution [2][3][4][5].…”

This study takes a new energy vehicle as the research object, establishing a three-dimensional model of the battery box based on CATIA software, importing it into ANSYS finite element software, defines its material properties, conducts grid division, and sets boundary conditions, and then conducts static and modal analysis to obtain the stress and deformation cloud maps of the battery box under three typical operating conditions, as well as the natural frequencies of the first 6 modes. Based on this, the ANSYS software’s topology optimization tool was utilized to successfully reduce the weight of the box by 6.8%. Following finite element analysis, the battery box’s performance satisfies the necessary standards in all aspects, demonstrating the viability of the lightweight solution.

The work puts forward a way to research the kinematics of front double wishbone suspension by virtue of analytical method. A way of discussing the kinematics of rear five-link suspension is put forward by means of space coordinate transformation. The influence of suspension spring stiffness on the suspension characteristics is analyzed. The vehicle frequency response index is deduced in view of theoretical model of equivalent handling stability. The relationship between the vehicle frequency characteristic index and the frequency of the steering wheel angle under the variation of spring stiffness is gained, and the influence mechanism of spring stiffness on the vehicle frequency characteristics is explained. The suspension spring stiffness is the optimization variable, the vehicle frequency characteristic index is the optimization objective, and genetic algorithm is used to optimize the vehicle frequency characteristic.
