【摘要】 活塞连杆机构是内燃机的动力传递部件,设计质量的好坏直接关系到整台机器的运行,而活塞承受交变的机械载荷和热载荷作用,是活塞连杆机构中工作条件最恶劣的零件。分别应用Pro/Mechanism和Pro/Mechanica对活塞连杆机构进行运动分析,确定活塞危险应力及应力集中位置,并对活塞结构进行了优化设计。该方法对于提高活塞连杆机构的设计质量,延长产品使用寿命,具有重要的作用。更多还原

【Abstract】 The piston linkage mechanism transfer the driving force of the internal-combustion engine,the quality of design is directly related to the operation of the machine,while the piston bear alternating mechanical load and heat load,it is the part of the most bad working conditions.The piston linkage mechanism motion analysis,application Pro/Mechanism and Pro/Mechanica proceeded the motion analysis of the piston linkage mechanism;determine the position of dangerous stress and the stress concentration of the piston,optimize the structure of the piston.The method improved the design quality of piston linkage mechanism,prolonged the service life of the product,it has an important role.更多还原
