摘要

针对某型内燃叉车在中低速工况下方向盘处振动明显,在对其转向系统进行模态分析的基础上,提出了一种基于均匀设计的结构振动优化优化方法,结合模态分析对其转向系统进行结构和振动同时优化。优化后的转向系统振动模态分析和实车试验结果均表明:改进后的转向系统结构在成本不变基础上,提高了其结构刚度,特别是叉车发动机处于常工况的低转速时,方向盘处的振动改善特别明显,振动加速度在X、Y、Z三个方向分别下降83.8%、90.3%、83.7%。该优化方法为车身、车架类结构优化设计提供参考。

Abstract

The modal analysis of steering system was made because of the excessive vibration of a certain forklift truck when the engine at medium and low speed conditions at first in this paper. The vibration optimum design was put forward to reduce the vibration of steering wheel by the method of Uniform Design. the test results show that the stiffness of improved steering system is increased and the vibration is decreased obviously on the basis of the invariability of costs,especially when the engine at low speed,the acceleration of vibration on direction x,y,z are reduced 83. 8%,90. 3%,83. 7% respectively. The optimum method provides references for the optimum design of body and frame type structures.
