Against classical dynamic balancers of crank and connecting rod mechanism , the test system has virtue hereinafter : ( 1 ) supporting structure adopt projecting beam uniquely . the signal of vibration provoked by crank and connecting rod mechanism revolving is concentrated to strain beam . the signal is not only abundance , but also easy to test and the test sensitivity is great 与传统的曲柄连杆机构动平衡机相比，这种测试系统具有以下优点：支承结构采用独特的悬臂梁式结构，曲柄连杆机构在运转过程中振动规律完全映射到支承梁的应变上，振动信号丰富且易测试、灵敏度高。
Furthermore , on the theoretics of the balancing machine and associations with the practicalities of the motorcycle crank , it has reasoned out the test principles and mathematic model of the unbalance mass checking device of the motorcycle engine crank set , which is supported by the new method 提出了新型试验方法所采用试验装置的测试原理和数学模型，并设计出了模型机。模型机正在制造中。第三：得到了一个结论：摩托车发动机曲柄连杆机构的动平衡率等于旋转不平衡量除以往复不平衡量。
Based on dynamic balance theory of normal rotate structure and crank - set , causation of inertia combined - force , a conclusion is drawn on the difference between the dynamic balance tests of single cylinder motor and normal rotate structure . that conclusion is the theory base of the whole test system 作为测试系统建立的基础，本文首先对一般回转体的动平衡理论、曲轴动平衡理论以及曲柄连杆机构惯性力产生的机理进行了较深入的研究，并在此基础上得出了单缸发动机曲柄连杆机构动平衡测试与一般回转体工件动平衡测试的不同之处，为测试系统的建立提供了理论依据。
The paper studied relations between academic inertial force graph in ellipse and experimental inertial force graph in " the 8 shape " , presented the inertial force experimental method through shifting cylinder in a testing bed on by a angle every time , the obtained graph and data represent inertial force principal parameters 摘要讨论了曲柄连杆机构的理论惯性力曲线（力椭圆）和实验惯性力曲线（力8字）的关系，提出在摆架上逐点偏移汽缸进行惯性力实验的方法，得到的实验惯性力曲线完全反映了惯性力的主要参数。
1the connecting lever is employd trundleing the needle with maintains a module chiefly to be used the motor . the compressor is with else crank connecting instrument , oad and the composition mould style fixs the necessary demand on the basis of the motorcycle in home and abroad , consider to exchange and the current demand , fix that the crank annuls that the use trundles the needle with maintains module kzk and a piston to annul in the way of kbk mould 1连杆用滚针和保持架组件主要用于发动机，压缩机和其它曲柄连杆机构上，外形尺寸和结构型式的确定根据国内外摩托车的配套要求，考虑到互换和通用的要求，确定了曲柄销用滚针和保持架组件kzk和活塞销用kbk型。
In this dissertation , integrated the reduce - vibration project of the engine of the motorcycle company , the eccentricity balance is used in the internal - combustion engine on the basis of analysis of the dynamic balance of the crank - connect rod mechanism for the internal - combustion engine 本文针对单缸内燃机的曲柄连杆机构的动平衡进行深入分析,在分析的基础上,针对单缸内燃机的特点进行动平衡设计,提出偏心滑块机构平衡方法,并针对偏心滑块机构在生产过程中一些关键技术进行分析设计计算。
