英斯特朗 --【挑战】模拟真实的碰撞动态过程

汽车制造商、客户和政府监管部门都把注意力集中在车辆碰撞时的乘客安全保护上。发生碰撞事故时保护驾驶员和乘客不受伤害，是车辆结构和被动安全系统（包括安全带、安全气囊、座椅、膝垫和其他吸能组件）的职责。其中包括被动安全组件，比如膝垫和坐垫，以及主动安全组件，它们具有乘员和车辆感应能力，能根据乘员和碰撞情况调整自身性能，从而起到保护保护驾驶员和乘客的作用。

任何情况下，不同碰撞场景以及不同的乘员情况对保护所有成员而言都是一个特别的挑战。通过汽车实际碰撞来测试每一个可能的组合既费时又昂贵，因此需要一个既可靠又现实的试验室测试系统来满足这种需求。

英斯特朗解决方案:

英斯特朗有限公司是台车碰撞模拟试验的业界领导者，将现实世界的真实碰撞场景引入试验室中。英斯特朗有限公司提供液压驱动和伺服控制的加速型台车碰撞模拟试验系统，通过精确地再现车辆碰撞的动态过程，对车辆的被动安全系统和组件进行比较和优化。试验系统具有重复性高、试验效率高，质量可靠等特点，大大地降低了测试成本。这些“台车试验系统”被用来优化车辆约束系统，使之在实车模型出现之前就具备功能和性能保证。英斯特朗有限公司在全球范围内已安装70多台台车碰撞模拟试验系统，其中包括14 套带主动俯仰模拟的试验系统，越来越多的OEM制造商和一级供应商在使用英斯特朗的台车系统。

Challenge:  Simulating Real-world Crash Dynamics

Automakers, consumers, and regulating governments are all focused on occupant protection in case of a vehicle crash.  Protecting drivers and passengers from injury during crash events is the job of both the vehicle structure and the passive safety system, which includes seat belts, airbags, seats, knee bolsters, and other energy-absorbing components.  Some of these are passive components like knee bolsters and seat cushions.  Others are active and have occupant- and vehicle-sensing capability to adjust their performance according to the occupant and crash circumstances.

The wide range of crash scenarios and broadly different occupant profiles create a particular challenge to protect all occupants under all conditions.  Crashing cars to test every possible combination is time consuming and prohibitively expensive.  Therefore a reliable and realistic laboratory-based test system is required to fill this need.

The Solution:

Instron is the world leader in crash simulation systems, which bring the reality of the real-world crash into the testing laboratory.  We offer servo-controlled reverse-acceleration systems which can accurately replicate the vehicle crash dynamics so that passive safety systems and components can be compared and optimized.  Our systems are highly repeatable and efficient to operate so that the cost of making tests is low.  These “catapults” can be used to optimize vehicle restraint systems and provide assurance of proper function before full-scale prototype tests are made.  With over 70 systems installed worldwide （14 of them are equipped with active controlled pitch motion simulation）and in use by more OEMs and Tier 1 suppliers than any other crash sled, Instron leads the market for crash simulation.
