Design and implementation of parallel standard dynamometer
Standard dynamometers are important instruments for quantity transmission of force value from primary standard or measuring standards to working measuring instruments.Limited by materials and working principles,the volume and weight of traditional dynamometers rapidly increase with the increase of working range.Specialized lifting equipment is essential for large force measuring in industrial sites,which is inconvenient for actual work.To this point,this paper designs a parallel standard dynamometer,which measures the force value through multiple force sensors in parallel.The influence of the number and arrangement of sensors on structural stress and deformation are analyzed through finite element simu-lation,the optimal parallel scheme is determined from the simulation results,and the accuracy of the de-signed parallel standard dynamometer has been verified through experiments.
