The study involves the determination of deformation that occurs in the arms due to loading calculated using a software-based finite element method. The dimensions of the arms are taken from the manufacturing data. For verification purposes, the transmission ratio distortion resulted from the finite element modeling is compared to the linearity error calculated from results of a series of calibration using load cells as force transfer standards. The finite element simulation results show that the transmission ratio distortion is linear and amounted to approximately 270 ppm at maximum capacity. In addition, the study also concludes that the transmission ratio decreases with increasing forces. These results are in agreement with previous calibration performed by KRISS, Korea and acceptance test results from PTB Germany.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Finite element modelling,Finite element simulations,Force standard machines,Force transfer,Linearity errors,Load cells,Transmission ratios[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Finite element method,Finite element modelling,Force standard machine,Lever-type force standard machine,Transmission ratio distortion[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
