水电部重点技措项目——重庆水文仪器厂流速仪检定车改造工程历经四年时间,于1986年10月结束。在调试过程中所产生的某些饥械问题有必要作以下分析,目的在于力求深化我们对检定车车速精度的认识。一、对检定车车体共振的一般分析检定车在某一特定速度下行驶将产生有阻尼的共振现象,它是自身系统在外界干扰力的作用下所作的受迫振动。例如电机转子制作时所产生的同轴度误差,它在运转中
Ministry of Water Power key technology projects - Chongqing Hydrological Instrument Factory velocity meter test car renovation project after four years, ended in October 1986. In the process of commissioning some of the hunger problems that are necessary for the following analysis, the purpose is to strive to deepen our understanding of the accuracy of the speed of the test vehicle. First, the test car body resonance General analysis Car driving at a specific speed will have a damping resonance phenomenon, which is its own system under the influence of external interference force made by the forced vibration. For example, the motor rotor produced by the coaxial error, it is running
