博士信箱

肥肥博士: 您好!我于2000年元月购买了一辆济南轻骑集团生产的轻骑·铃木GS125(~S125)型摩托车。该车车架号107272,发动机号QS157T-M9905129797,至今已行驶1.8万公里,总的来说质量不错。现就以下几个问题向您请教。 1.该车在1.4 万公里时点火器损坏,由于原装价格过高,便更换了一个国产     

GS125化油器故障四则

汽油发动机运转,必须要有汽油和空气,化油器的作用就是将作为燃料的汽油和空气进行混合,变成容易燃烧的状态,然后送入燃烧室内,轻骑GS125所使用的是真空膜片式化油器,靠其真空室内真空度的大小来控制柱塞的上下移动,实现改变可燃混合气浓度的功能,GS125发动机所使用的化油器盘如图1所示。故障一:GS125摩托车热车行驶过程中,停车熄火。造成此种故障现象的原因很多,经检查电路及火花塞等易出现故障的零部件后,最终确定是因为怠速空气调整螺钉调整不当,造成怠速混合气过浓所致。汽油与空气的混合气体若能正常燃烧,需满足过量空气系数的要求(过量空气系数=燃烧1克汽油所实际消耗空气量/

摩托车车架断裂问题探析

摩托车车架常见断裂部位，骑式车常位于主梁和车架后减振支撑部位的悬臂梁处；踏板车常位于主梁和踏板后部弯角部位。引起断裂的主要原因是车架前部不断受到来自地面和前轮的冲击，弯距和冲击力过大；而后部悬臂梁受重载弯距和后轮冲击力作用，发生断裂的几率也很大，但具体到某一款车架而言，断裂部位主要取决于结构形式、材料选用和载荷特征，需要具体问题具体分析，不能一概而论。     

基于多刚体动力学理论的摩托车平顺性仿真研究

基于ADAMS软件,对摩托车后悬摆臂长度和后悬弹簧倾角变化时,后悬架的非线性特性进行分析,并建立了摩托车整车系统参数化振动模型,以B级路面谱为振动激励对某骑式摩托车进行随机振动分析,综合研究了摩托车悬架弹簧刚度和阻尼、后悬摆臂长度以及摆臂与弹簧间夹角对整车平顺性的影响。     

摩托车车架可靠性的计算机分析

车架强度是车架设计中需要考虑的首要问题,它关系到摩托车整车的行驶安全性.通过分析得出:1)摩托车车架弯曲方管处有必要采取加强措施,一是弯曲处本身,二是方管根部应力过渡区;2)弯曲方管与转向柱支撑柱若换用新材料钢种,要提高强度级别;3)应提高结构件连接处的焊接质量,对焊接产生的焊缝采取强化手段.     

A Motorcycle Multi-Body Model for Real Time Simulations Based on the Natural Coordinates Approach

This paper presents an eleven degrees of freedom, non-linear, multi-body dynamics model of a motorcycle. Front and rear chassis, steering system, suspensions and tires are the main features of the model. An original tire model was developed, which takes into account the geometric shape of tires and the elastic deformation of tire carcasses. This model also describes the dynamic behavior of tires in a way similar to relaxation models. Equations of motion stem from the natural coordinates approach. First, each rigid body is described with a set of fully cartesian coordinates. Then, links between the bodies are obtained by means of algebraic equations. This makes it possible to obtain simple equations of motion, even though the coordinates are redundant. The model was implemented in a Fortran code, named FastBike . In order to test the code, both simulated and real slalom and lane change maneuvers were carried out. A very good agreement between the numerical simulations and experimental test was found. The comparison of FastBike 's performance with those of some commercial software shows that first is much faster than others. In particular, real time simulations can be carried out using FastBike and it can be employed on a motorcycle simulator.     

Effect of Frame Compliance on the Lateral Dynamics of Motorcycles

The lateral dynamics of an uncontrolled motorcycle, running on a straight, level road surface, is investigated in this paper. The structural compliances in the front and the rear frames of the motorcycle are taken into account by introducing additional degrees of freedom in the analysis. The kinematics of the tires is represented by linear differential equations which are based on the taut-string model of pneumatic tires. The linear differential equations of motion are solved to yield the eigensolutions of the system. Numerical results, obtained for parameters corresponding to a Honda CB750 motorcycle, are presented and discussed.     

A study on the stability of a motorcycle wheel–swingarm suspension with chain transmission

The present study describes a possible driving mechanism for a self-excited oscillation observed in motorcycle dynamics, often referred to as chatter. This phenomenon, affecting the performance of road racing motorcycles, has been simulated in straight running braking manoeuvres with multibody motorcycle models. It involves rear suspension bounce and driveline oscillation in the frequency range between 17 and 22?Hz. A simplified model of a motorcycle rear suspension with chain transmission is proposed and its stability in equilibrium configurations is studied via eigenvalue analysis. The sensitivity with respect to all its governing parameters is analysed by means of stability maps and the self-excitation mechanism is explained with the aid of energy balance analysis and phase diagrams. It is found that the key role for the instability onset is played by the gradient of the nonlinear characteristic slip function of the tyre.     

Dynamic analysis and control of an anti-lock brake system for a motorcycle with a camber angle

This paper analyses the dynamic response of a motorcycle with an anti-lock brake system (ABS) and camber or steering angle. Most studies have assumed that motorcycles brake in a straight line – that is, without a steering or camber angle. In this work, the performance of an ABS modulator is designed and analysed at first. Then, a controller is designed for motorcycle turning. The controller uses angular acceleration and the pressure value in brake calipers on the front and rear wheels, camber angle and lateral acceleration as commands to control brake pressure on each wheel to prevent wheel locking. The equation of motion for a motorcycle is based on Weir's equations. This motorcycle model combines a mathematical equation of the ABS modulator, tyre model and controller in simulations.

五羊铝车轮轴承外圈松动打滑问题的分析及改进

通过对五羊款摩托车后轮进行结构分析,找出了WY125一端轴承受力过大是产生轴承外圈松动打滑的主要原因,但仅靠增加受力较大一端轴承的承载能力显然不是最合理的方法。通过减小受力大一端轴承的承载能力,使两轴承载荷均匀分布,产品改进后,样品经10000km路试后效果良好,市场反映普遍良好。     

三轮摩托车无后桥调节杆机械式制动系统的可行性分析及CAD辅助设计

大部分三轮摩托车和三轮电动车机械制动型后悬架均采用有后桥调节杆结构,该结构的后悬架系统对制动系统影响不大,一般均能保证制动系统性能稳定,但后桥调节杆大多采用正、反向调节螺栓、螺母结构,行驶中容易松动或脱落,造成后桥中心线相对车身倾斜微小角度,车身纵向中心偏离直线行驶方向,存在左右车轮制动器制动不平衡等安全隐患。
