In this article, the wheel tractor is treated as a vibration system with two degrees of freedom. Using the solution of the differential equations of such a system, the characteristics of the free vibrations of tractor is analysed. The two partial frequencies ("constrained frequencies" )are suggested to be the fundamental critenia for wheel tractor riding quality. Some testing result of partial frequency are given, and a method of calculating forced vibrations in two typical cases is introduced, i e., when tractor runs over a single obstacle and over continuous obstacles. The result of such calculation is compared with those obtained during experiments on turning disk testing stand. With the aid of this method of calculation, the influence of factors such as distribution of masses, tyre inflation pressure, front suspension and seat cushion on the vibration characteristics of both tractor and operator is discussed. Means of improving riding quality are also suggested.

本文首先把轮式拖拉机简化为两个自由度的振动系统,然后运用该系统振动微分方程的解,分析了机体自由振动的特点,提出把偏频作为评定轮式拖拉机平顺性的一个基本数据,并列举了偏频试验的结果。 文中在分析机体强迫振动时,建立了通过连续和单个不平度两种典型情况的计算方法,并与在转盘试验台上进行相应试验的结果加以比较验证,然后用该计算方法来讨论拖拉机机体质量分布、轮胎气压、前轴悬架、座椅等决定机体和拖拉机手振动的主要结构参数对振动的影响规律,提出改善轮式拖拉机平顺性的途径。

In the present paper, the tractor drawing an unbalanced trailer or vehicle is simplified into a spring-mass-damping system of multi-degree of freedom. The power spectrum density and mean square value of acceleration at every output position including the driver's seat are computed by means of solving the frequency response function, so as to show the changes of vibration magnitude through parameter-transformation. In addition to the auto-spectrum density of every input point and cross-spectrum density...

In the present paper, the tractor drawing an unbalanced trailer or vehicle is simplified into a spring-mass-damping system of multi-degree of freedom. The power spectrum density and mean square value of acceleration at every output position including the driver's seat are computed by means of solving the frequency response function, so as to show the changes of vibration magnitude through parameter-transformation. In addition to the auto-spectrum density of every input point and cross-spectrum density between the front and rear wheels, the cross-spectrum density between the right and left wheels are also considered in calculation based on the relevent road-spect rumdata. In the study of comfortability of the seat, some rules for the seat vibration magnitude which changes with parameter-transformation have been obtained. These may be used in the future designing as reference. The calculated result are approximately equal as compared with the experimental values.The experiments were carried out on the auto testing runway at Hot-Humidity Experimental Station of Hainan.

本工作是把牵引单轴拖车的拖拉机或汽车简化为多自由度的弹簧-质量-阻尼的振动系统,通过求解频率响应函数计算包括座椅在内的各输出点的功率谱密度和加速度均方值,从而通过参数改变予示振动量的变化。在计算中除考虑了多点输入的自谱及前后轮之间的互谱外,还根据有关路面资料考虑了左右轮之间的互谱。结合乘坐舒适性研究,绘出了座椅振动量随各参数变化的一些规律,可为今后设计工作参考。计算值经与实际测量值验证基本相符。

This paper discusses the effect of cam profile on the vibration, noise and durability ofengine valve mechanism—a long chain vibration system. Experiments were taken on aI-head 6-inline 101. 6×114. 3 mm. gas-engine with two cam profiles—one of original design,a composite-cycloid curve; and the other a new design, a sine-parabolic curve. The stressof rocker arms was measured and recorded with strain gage; and the film recording thestresses was amplified and calibrated by an optical projector for rough...

This paper discusses the effect of cam profile on the vibration, noise and durability ofengine valve mechanism—a long chain vibration system. Experiments were taken on aI-head 6-inline 101. 6×114. 3 mm. gas-engine with two cam profiles—one of original design,a composite-cycloid curve; and the other a new design, a sine-parabolic curve. The stressof rocker arms was measured and recorded with strain gage; and the film recording thestresses was amplified and calibrated by an optical projector for rough quantitative analysis. The results were correlated with theoritical, calculations using mono-mass dynamicmsethods.The resonant frequency of this valve mechanism was calculated, and methods of raisingthis frequency was discussed. The valve mechanism noise was measured, spectrum analysedand compared for two cam profiles. The valve spring surge was investigated with highspeed photography. Finally, a 100-hr. durability run was conducted using an over-speedmotored engine for these two cam profiles. This paper concluded with that the new profilewas better than the old one, and gave some advices on valve mechanism design.

本文曾经1978年10月在汽车学会第二届年会宣读。讨论凸轮轴凸轮型线对发动机气门机构——一个长链状振动系统——的振动、噪声与可靠耐久性之间的关系.对一台顶置气门直列6缸φ101.6×114.3毫米汽油机的两种凸轮型线进行了比较试验,一种型线是原来的设计、组合摆线,另一种型线是新设计的正弦抛物线。试验时在摇臂上贴应变片、测量并记录其应力,然后把记录其应力的胶卷在投影放大仪上校正、放大,作粗略的定量分析。分析的结果与按单质量动力学理论计算值比较。本文计算了气门机构的自振频率,并讨论了提高此频率的方法。测量了气门机构噪声,并作频谱分析。对二种凸轮型线的噪声进行对比。用高速照相法研究了气门弹簧喘振。最后对二种凸轮型线的气门机构进行了在超速运转的拖动的发动机上100小时的可靠性试验。结果是新设计的型线在所有方面都比旧的好;并对气门机构的设计提出几点意见。
