摘 要
本文油机对四缸油机的连杆进行了结构设计计算,并对运动学和动力学的理论分析。首先,以运动学和动力学的理论知识为依据对连杆的运动规律以及在运动中的受力等问题进行详尽的分析并得到了精确的分析结果。其次分别对、连杆以及结构设计并进行了结构强度和刚度的校核。再次,应用CAD软件:Pro/E建立了连杆的几何模型,在此工作的基础上,关键词:;连杆;
ABSTRACT
Taking 4110 as the reference parameters of the diesel engine, four-cylinder diesel e-
ngine connecting rod on the design and size were calculated, and linkage to the theory of kinematics and dynamics analysis, and finally the use of Pro / E for the use of three-dim-
ensional modeling ANSYS finite element analysis carried out. First, the theoretical knowledge of kinematics and dynamics based on the movement
of connecting rod and the force in motion a detailed analysis of such issues and get accurate results, while the materials were used on the rod comparison and analysis. Followed by on the connecting rod, connecting rod shaft and the connecting rod small end and size of stru-
ctural design calculations, and were checking the structural strength and stiffness. Again, application CAD software: Pro / E software to establish a link of three-dimensional geome-
tric model, based on the work in this, but also on the static on the link under the two special conditions; tension, compression conditions were the force calculation, and then link into ANSYS three-dimensional geometric model is defined in its properties, meshing, impose constraints and loads, and finally calculated to achieve the purpose of checking the strength rod
Key words: Diesel engine;Connecting rod;Strength check;Pro/E;ANSYS
