Fatigue strength analysis on truck powertrain Rear Suspension bracket
Computer-Aided Engineering, 2013Co-Authors: Fan WenfenAbstract:As to the new Rear Suspension bracket which is designed for a truck powertrain,the linear hardening elastic-plastic model of material of the bracket is built in Abaqus and the strength of the bracket is calculated under vertical impact conditions. The results show that the von Mises stress in hazardous location is less than the material yield stress,that is the strength requirements is met in vertical condition. The von Mises of the Rear Suspension bracket is also calculated respectively when the vertical acceleration is-2g and 4g,and the fatigue safety factor of the Rear Suspension bracket is calculated by FEMFAT,which verifies that the bracket meets the fatigue strength requirements. The brackets are assembled in a certain truck and tested on the strengthened road,and the brackets is not damaged after twenty thousand kilometers road test,which verifies the reliability of the calculation.

Modeling and Dynamic Character Analyzing of Twist Beam Rear Suspension on ADAMS
Computer Simulation, 2006Co-Authors: Gao Qiu-jinAbstract:Two methods of modeling the twist beam Rear Suspension in ADAMS were introduced.One is equivalent dynamics of milt body model,and another is flexible-rigid body model.The dynamic character of the twist beam Rear Suspension was analyzed through simulating the two methods,and the difference of two methods was discussed according to the results of the simulation.Also two models were testified by the experiments.The research supplied new ways of modeling,which could be used to discover the dynamic character of Suspension and uneven wear of tire.

topology optimization of vehicle Rear Suspension mechanisms
International Journal for Numerical Methods in Engineering, 2018Co-Authors: Suh In Kim, Seok Won Kang, Joonhong Park, Yoon Young KimAbstract:Summary As Suspensions critically affect the ride and handling performance of vehicles, considerable efforts have been made to improve their design by an optimization method. In this paper, we propose a topology optimization based method for Suspension synthesis by employing a three-dimensional model constructed with nonlinear bars and zero-length springs that discretize the three-dimensional space between the chassis frame and a vehicle wheel. For optimization, bar cross-sections and spring stiffness values are used as design variables alongside the nodal positions of bar elements as shape optimization variables to simultaneously optimize the topology and shape. To verify the proposed approach, two types of design problems were solved: recovering known Suspension mechanisms for a given set of wheel trajectories and synthesizing unknown Suspension mechanisms that satisfy several design constraints typically used in the automobile industry. Through these examples, possibilities to design new and advanced Suspensions by the proposed optimization method are clearly demonstrated.
