| Development of analytical process to reduce side load in strut-type suspension Y. I. Ryu/D. O. Kang/S. J. Heo/H. J. Yim/J. I. Jeon
The Journal of Mechanical Science and Technology, vol. 24, no. 1, pp.351-356, 2010
Abstract : Methods have been developed to reduce the side load and friction force acting on the shock absorber inherent in the MacPherson strut
system, popularly used in vehicle suspension systems. Reducing this friction force is one of the most important issues in improving the
ride comfort of a car. The side load of the shock absorber can be reduced by controlling the force line of the coil spring. To reduce the
side load, we designed an S-shaped coil spring. For the design of the side load spring, we also developed an analytical process, which
utilizes finite element analysis and mechanical system analysis. All analysis results for the stiffness, stress, fatigue life, and spring force
line were validated through experiments.
