摘要
为提高车载称质量系统的效率及可靠性,课题组设计了一种方便安装和便于应用的粘贴应变式车载称质量系统。基于应变片原理和惠斯顿电桥理论,课题组选定合适的应变片并设计了应变片贴片工艺;借助粘贴在汽车钢板弹簧上的应变片,通过钢板弹簧悬架系统的变形获得承受的载荷。此外还提出一种多次标定方案,该方案将各板簧采集到的应变(电信号)与货车的总载质量联系起来。结果表明:该系统不仅具有可靠、便捷等特点,还能有效提高交通称质量的效率。该系统能改善车载称质量效率低的状况,优化交通称质量系统。
In order to improve the efficiency and reliability of the vehicle-mounted weighing system,a paste strain-type vehicle-mounted weighing system that is easy to install and apply was designed.Based on the strain gauge principle and the Wheatstone bridge theory,the appropriate strain gauge was selected and the strain gauge patch process was designed.With the help of the strain gauge sticking on the automobile leaf spring,the load received was obtained by the deformation of the leaf spring suspension system.In addition,a multiple calibration scheme was proposed,which linked the strain(electrical signal)collected by each leaf spring with the total load of the truck.The results show that the system not only has the characteristics of reliability and convenience,but also can effectively improve the efficiency of traffic weighing.This system can improve the low efficiency of vehicle weighing and optimize the traffic weighing system.
