【Abstract】 The dynamic measurement and quantitative analysis on the force and torment transferred from the tire contact patch contributes significantly to the research on the dynamic performance of motor vehicle and the road damage mechanism. Several road-based and vehicle-based methods are introduced such as WIM(weigh-in-motion),wheel scales methods, tire deflection measuring, tire pressure transducer and strain gaged axle method, etc.The WFT (wheel force transducer) is brought forth in detail about its development and status up to now, design principle, performance evaluation, etc.更多还原
