Design of Semiautomatic Standardizing Machines for Load Cells Testing

The paper deals with the systematic synthesis of semiautomatic standardizing machines used for load cells testing. The principal requirements are formulated and an evolutionary (such as followed in optimal design) is given. Of special note is the extreme accuracy required (0.01 percent) and acheived in a relatively large mechanical system. The paper includes some results of analyses made for two types of machines and data obtained from tests and long-term utilization of these machines.
