161.产品使用过程中的延伸设计模型
[汽车制造业] [2014-07-24]
This paper presents an Extension theory-based approach to product design,the basic idea is to use combined qualitative and quantitative modeling in Extenics to describe the user's possible product using process as well as the corresponding internal structural,assembly and motion relationships of product, then mark the contradictory problems via the correlation between the magnitudes and characteristics of various elements, and then obtain the design scheme meeting the requirements by extension transformation method.

163.铝合金汽车轮毂的抗疲劳设计研究
[汽车制造业] [2014-07-24]
In this study,a 14×6JJ a-alloy automobile wheel was used as the object,the fatigue strength and lifetime of the wheel suffered from varying amplitude load were predicted with a cumulative danage theory (the modified Miner theorem),which was considered to be accurate and secure,based on the analysis of load spectrum.The predicted lifetime was verified using a reliability theory.The results showed that,the modified Miner theorem was reliable in the prediction of the lifetime of an automobile a-alloy wheel.

164.基于CAN/LIN总线的汽车车灯的故障诊断设计
[汽车制造业] [2014-07-24]
Based on the research of the CAN/LIN bus communication protocol,an automobile lamps diagnostic system based on the CAN/LIN bus is designed.After the completion of the software and hardware designs of CAN nodes,LIN nodes and CAN/LIN nodes,the faults of automobile lamps can be successfully diagnosed.LIN node collects light switches and the gateway controls the car light's status via detecting the data frame on the LIN bus.The design and complementation of CAN node,LIN node and CAN/LIN gateway was finished,which made it possible to detect failures in vehicle.

165.基于车对车通信的安全应用的轻型车碰撞避免需求与对策配置文件
[汽车制造业] [2014-07-24]
This report discusses light-vehicle crash countermeasure profiles and functions for five target pre-crash scenario groups based on vehicle-to-vehicle (V2V) communications. Target pre-crash scenario groups include rear-end, lane change, opposite direction, junction crossing, and left turn across path from opposite direction (LTAP/OD) crashes involving at least one light vehicle (e.g., passenger car, van, minivan, sport utility vehicle, or light pickup truck with a gross vehicle weight rating of 10,000 pounds or less). There are 10 pre-crash scenarios in these groups to be addressed by V2V-based crash countermeasures. Kinematic equations are presented for the time-to-collision and avoidance maneuvers to identify information needs for these crash countermeasures. Information needs are translated into countermeasure functional requirements based on relevant safety applications devised in two prior research projects dealing with cooperative V2V communications and autonomous vehicle-based sensing systems. This report identifies two target pre-crash scenarios that would require new safety applications not developed in prior projects, including the LTAP/OD and opposite direction/no vehicle maneuver pre-crash scenarios.

166.加州病死率评估与控制评估(FACE)报告:汽油倒进车辆点燃导致汽车机械模具热烧伤
[汽车制造业] [2014-07-24]
An automotive mechanic died when gasoline he was pouring into a vehicle ignited and burned him. The victim had just replaced a gas tank on the vehicle. He was using a bucket to pour gasoline into the new fuel tank that did not have the filler hose installed. The fuel spilled onto a wire cage-covered incandescent drop light under the vehicle, which ignited the fuel causing the fire. The victim ran from the vehicle with the bucket of fuel, leaving a trail of spilled gasoline which ignited. The ignited trail of fuel caused the bucket of fuel to also ignite, burning the victim. Contributing factors identified in this investigation were the positioning of the drop light, the type of drop light used, the use of a bucket to store and pour gasoline, and the filling of an incompletely assembled fuel system. The CA/FACE investigator determined that, in order to prevent fires within an automotive repair shop, owners should ensure that: 1. Sources of ignition are eliminated when work involves flammable liquids. 2. When refueling vehicles with a portable container, the container should be equipped with an automatic closing cap and flame arrester. 3. Gas tanks are properly installed before refueling.

168.基于免疫PID控制的车辆防制动系统控制算法的研究
[汽车制造业] [2014-07-24]
Because the classic PID control doesn't satisfy the demand of automobile ABS in all conditions and it is short of an ability of identifying road surface,fuzzy control is short of an ability of remove systemic stable error and it doesn't make automobiles keep higher control precisions,a dynamic mode of the wheels is built when an automobile is braking at first,aiming at automobile ABS,a immune PID control algorithm based on classic PID is presented and used in automobile ABS system.Compared with the classic PID control algorithm and fuzzy control algorithm,the simulation result shows that the immune PID control algorithm has a shorter stabilization time,a smaller excess of system output,fewer response time and shorter braking distance,it is superior to the classic PID control algorithm and fuzzy control algorithm.The immune PID control algorithm has a higher application value.
