摘要
论述了电动独立加码静重式力标准机的工作原理和结构特点,以所研制的500kN静重式力标准机为例,研究了独立加码方法的运动规律,推导了驱动机构的功率、速度、扭矩的计算公式。500kN静重式力标准机已在中航电测仪器股份有限公司应用运行3年,应用实践表明,所提出的独立加码技术方法是可行的和有效的。独立加码力标准机具有精度高、工作可靠、结构简单、效率极高、测力范围大、自动化程度高和成本低等诸多优点,为力基准机和标准机的发展提供了一种新的理论方法和试验依据。
The working principle and structure features of deadweight force standard machine with electric drivers for every weight are introduced.For the 500kN deadweight force standard machine,the characteristics of motion of the drivers are discussed,and the calculation formulas of power,velocity and torque are established.The 500kN deadweight force standard machine has been used in Zhonghang Electronic Measuring Instruments Co.,Ltd.for 3years.The practical application shows that the technical method of independent load is feasible and effective.The independent load force standard machine has the advantages of high preciseness,high reliability,high efficiency,simple construction,wide range of force measure,automation work and low cost,and it provides a new theoretical method and experimental basis for the development of norm force machine and force standard machine.
