课程名称：汽车工程导论 - 性能 课程概述： 汽车设计受到性能目标的驱动，理解这些性能指标和特性是整体车辆设计过程中的重要部分。本课程旨在提供对典型内燃机汽车各个性能领域的基础理解。 课程内容包括： - 车辆加速机制 - 内燃机基本工作原理 - 牵引力和动力限制下的加速 - 最高速度的限制 - 牵引力与发动机扭矩之间的关系 - 传动系统的必要性 - 影响车 Handling 的因素 - 轮胎的重要性 - 硬悬挂与软悬挂 - 道路抓地力与稳定性 - 处理性能测试类型 - 转向性能 - 制动的基本物理学 - 制动系统的工作机制 - 停车距离推导 - 滑移比及其影响 - 防抱死制动系统的工作原理 - 制动与操控之间的关系 - 振动的概念、乘坐舒适性与NVH（噪声、振动、粗糙度）的区别 - 噪音的来源及路径 - 振动的基本概念及其评估方法 - 车辆耐久性的重要性 - 材料在强度方面的属性 - 弯曲和扭转刚度 - 强度与重量的权衡 - 在车辆设计过程中的耐久性设计考虑 - 发动机中的能量流动及损失类型 - 相对损失的贡献 - 特定燃油消耗 - 热效率及其改进方法 - 驾驶模式和环境对燃油效率的影响 - 提升车辆燃油效率的途径 本课程旨在为初学者提供友好的学习体验，采用“基本原理”的方法，数学要求较少。无论是学生、汽车行业工程师，还是对汽车感兴趣的爱好者，均可通过本课程全面理解关键性能标准，并建立对相关原理的概念性直观理解。课程不深入探讨任何一个领域，而是关注“重要的内容”。如果你希望获得高度分析的方法，课程可能不适合你；但如果你已掌握基本的汽车知识并希望了解性能的工程连接，本课程将非常适合你。课程内容结合了学术知识和个人在汽车制造企业担任机械设计工程师期间的经验与学习。
Automotive Design is driven by the targets set for performance. Understanding these performance metrics and characteristics is a very important part of the overall Vehicle design process.This course aims to provide an idea of each of these specific areas of performance related to the Typical IC (internal combustion) engine Vehicle.Topics coveredMechanism of Acceleration of the VehicleBasic working principles of IC engineTraction and Power limited accelerationLimits of Top speedRelations between tractive force and engine torqueNeed for a transmission Factors which affect Vehicle HandlingImportance of the TireStiff vs Soft suspensionWhat is Road holding and GripTypes of tests performed for handlingSteering performance Basic Physics of BrakingWorking mechanism of a Brake systemStopping distance derivedSlip ratio and its affectsAnti lock braking system workingRelations between Braking and Handling behaviorWhat are vibrations,Difference between Ride and NVHTypes of sources, pathsTypes of Noise Basic Concepts of VibrationsSensitive touch points related to NVHHow NVH performance is evaluated?Different aspects of Vehicle DurabilityImportance of Material properties to strengthBending and Torsional stiffnessTrade off of strength vs WeightConsiderations for Design for durability in Vehicle design processFlow of energy in an engineTypes of lossesRelative Contribution of those lossesSpecific Fuel ConsumptionWhat is Thermal efficiency and ways to improve itAffect of Driving patterns and environmentWays to improve Vehicle Fuel efficiencyThe course is designed to be Beginner friendly and consists of minimal Math with a "First Principles" approach.If you are a student, engineer working in Automotive industry or an enthusiast wanting to learn about Automobiles this course will give you a Holistic understanding of Performance Criteria which matters and build a conceptual intuitive understanding of underlying principles.This course doesn't deal in-depth in any of the area only deals with "what matters".This course may not be for you if you are looking for a highly analytical approach.This course is suitable for you if already know some basics of cars but want to know the engineering connections in performance.Knowledge compiled in the course is partly academic and partly related to my experiences and learning throughout my working stint at an Automotive manufacturer as a mechanical design engineer.
