Compliance of Self-adaption Suspension Group Systems in Selfpropelled Transporters
摘要
Abstract
Through the descriptions and effect evaluations of the compliance of self-adaption sus-pension group systems in self-propelled transporters,a kind of self-adaption suspension group system was improved and designed in view of the present traditional hydraulic spring suspension system,and a nonlinear mathematical model of the transporter and self-adaption suspension group system was es-tablished.Based on the six axis of self-propelled transporter which was loaded 3200 kN,the simula-tion model of hydraulic spring suspension system and self-adaption suspension group system was built with random road surface excitation for inputs under no-load and full load conditions.Simulation ana-lyses and field tests show that the compliance coefficient of the improved self-adaption suspension group system is increased by 103.8% and 55.1% under no-load and full-load conditions respectively, the output forces of the system hydraulic cylinder are more gentle and the compliance performance of the system is better.The ability to resist shock vibrations and the performance to ride comfort im-provements have remarkable effects in the self-propelled transporter driving processes using the im-proved self-adaption suspension group system.关键词
