摘要
随着科学技术的发展,节能减排早已是机械设计一项重要的设计理念。汽车起重机的支腿高强度轻量化改进对吊装行业尤为重要,由于支腿的液压装置总体结构较为笨重,针对汽车起重机H型支腿设计出一种新型的活动支腿,用简单的连杆结构以及一套尺寸较小的液压装置即可实现延伸支撑,并通过电控液压系统自动伸缩至平衡状态。精确计算出起重机工况下每一个支腿单元的工作载荷,并使用ANSYS-workbench软件进行有限元分析,最终通过强度及刚度的校核,满足了支腿的使用条件,提高了整车的性能。
With the development of science and technology, energy saving and emission reduction has long been an important design concept in mechanical design. The improvement of high strength and lightweight support legs of truck cranes is particularly important to the hoisting industry. Due to the cumbersome structure of the hydraulic device of the leg, a new type of movable leg was designed for the H-type leg of the truck crane. The extension support could be realized with a simple connecting rod structure and a small hydraulic device. Through the electronically controlled hydraulic system, it could automatically expands and contracts to the equilibrium state. the working load of each leg unit under the crane working condition was accurately calculated, and the ANSYS-workbench software was used for finite element analysis. Through the check of strength and stiffness, the use conditions of the legs are satisfied, and the performance of the whole vehicle is improved.
