电动助力车的车架与车体设计
摘 要
我国已进入老龄化社会，为此，设计老年人专用的电动助力车会带来很大的市场潜力。但是传统的设计方法在车架设计过程中，在定型之前往往经过多轮设计，通过样品制造—>试验—>修改—>再设计的往复，周期长，人力、物力消耗大。针对这种情况，本文主要研究使用先进的软件平台，在计算机上完成电动助力车车架与车体设计及车架有限元强度校核的过程。
使用计算机软件进行车体设计可以减少物理样机的试制次数，减少台架试验和经验设计的工作量，从而达到缩短产品开发周期，降低开发费用，增强产品竞争力的目的。电动助力车是通过车架把电动机、座椅和车身中各主要零部件连成一个整体的。车架的功用是作这些零部件的安装基体，承受这些它们的质量及其传给车架的各种力和力矩。车架的刚度、强度对整车的舒适性、行驶平顺性、安全性及寿命都有很大的影响。车架设计的优劣将直接影响整车的行驶和安全性能。因此通过有限元分析的方法来研究车架的结构性能，从而在设计时考虑车架的优化，在提高行驶平顺性和振动舒适性，保障车辆安全性等方面具有十分重要的现实意义。工作的主要内容可以概括为两个部分：
1．设计车架并进行实体建模。根据已知技术要求，确定车架设计方案，并应用Pro/Engineer软件建立车架、座椅、车壳以及一些其他相关零部件的实体模型，直观的把各零部件之间的相对位置关系、装配关系表现出来。
2．对车架进行有限元强度校核。将在Pro/Engineer中建立的车架模型导入有限元分析软件ANSYS中，应用ANSYS研究车架的结构性能，校核车架强度。分析后处理结果，得出有效结论。

The car and bodywork designs of the dynamoelectric help car
Take off to want
The our country hases already entered the advanced age to turn the society, for this, design the old people appropriative of dynamoelectric help car will bring the very big market potential.But the traditional design method is in car install account process, before already set usually through several designs, pass the sample manufacturing-> experiment-> modification-> the back and forth that design again, period long, the manpower, material resources consume greatly.Aim at this kind of circumstance, this text main research usage forerunner's software terrace, at compute on board complete the process of the dynamoelectric help car car and bodyworks design and the pit in a strength school.
Use the calculator software carry on the bodywork design's can reduce the physics kind machine to manufacture the number of times on a trial basis, reducing the pedestal experiment and the experience design of workload, thus attain to shorten the product development period, lower the development expenses, strengthen the purpose of the product competition ability.The dynamoelectric help car is to pass the car the electric motor, a chair and carriages in each main zero partses connect a whole.The effect of the car is the gearing 基 body that makes these zero partses, bearing these their quantities and it passes the various dint and dint 矩s of the car.The car just comfort of degree, strength to the whole car, drive the going smoothly, safety and life span to have the very big influence.The car install the good and bad for account and will affect the whole car to drive directly and safe function.Therefore pass an analytical method to study the structure function of the car, thus while design consider the car excellent to turn at raising to drive the going smoothly and vibrate the comfort, guarantee the vehicle safety etc. has very important realistic meaning.The main contents of the work can generalize to two parts:
1. the design car carries on the entity to set up the mold also.According to have already known the technique request, make sure that the car installs to account the project, and apply the Pro/ Engineer software establishment car, a chair, the car hull and some other related zero entity models of the partseseseses, keeping the view of relate to, assemble the relation performance to each zero opposite position between partses to come out.
2. carry on a strength school pit to the car.Duct into a model of car build up in the Pro/ Engineer in an analysis software ANSYS, apply the structure function of the ANSYS research car, the car a strength of the school pit.Handle the result after analyze, get valid conclusion.
