摘　　要：以民生产品电动两轮车辆作为设备设计研究开发的测量对象,基于质量反应法下的力矩平衡原理开发设计出的两轮车辆质心自动测量系统,利用车轮外廓圆形的特征设计出双辊轮自动对正支撑装置,同时配合使用双向同步夹紧装置,实现车辆在整个测量过程中的垂直度和前后轮轴的平行度;通过导入高精度位移传感器配合PLC程序运行控制,不仅实现测量过程的可重复性、可追溯性,还实现质心测量过程的自动化。试验结果表明,该两轮车辆质心自动测量系统具有检测精度高、检测数据稳定性好、检测高效便捷、自动化程度高等优点。另对该系统延伸使用进行推广介绍,具有广泛的应用前景。Taking the electric two-wheeled vehicle as the research object,based on the moment balance principle of the mass response method,an automatic measurement system for the centroid of the two-wheeled vehicle is developed.The double roller automatic alignment support device is designed based on the characteristics of the round wheel profile,and the perpendicularity of the vehicle and the parallelism of the front and rear axles during the whole measurement process are realized by using the two-way synchronous clamping device.By introducing the high-precision displacement sensor and PLC program operation control,the repeatability and traceability of the measurement process is realized,as well as the automation of the measurement process.The test results show that the automatic measurement system for the centroid of the two-wheeled vehicle has the advantages of high accuracy,good stability,high efficiency,and high level of automation.The extended use of the system is introduced,which has broad application prospect.
