应用动态设计方法建立了汽车起重机行驶工况力学计算模型,通过大量计算结果,分析了行驶速度与最大冲击响应关系和车轮反力的表现特点,说明用动载系数法计算结构强度的缺陷,并提出了改进意见。
The dynamic calculation method is used to establish the mechanics calculation model of the truck crane driving condition. Through a large number of calculation results, the characteristics of the traveling speed, the maximum impact response and the wheel reaction force are analyzed. The disadvantages of calculating the structural strength by the dynamic load coefficient method Put forward suggestions for improvement.
