To address the issue of low weighing accuracy caused by the tilt angle of the scale body during the use of electronic hand pallet truck forklift scales, a multi-directional variable-angle tilt simulation and measurement experiment platform was constructed to simulate the different tilt states of the forklift scale. By analyzing the weight and tilt angle change data measured by the experiment platform, a compensation algorithm model for the weighing error of the electronic forklift scale under the tilt state was established, and the model parameters were identified using both the least squares method and the multilayer perceptron non-linear regression. The compensated forklift scale with a range of 1 500 kg and sensitivity of 0. 02 kg was tested under tilt experiment, and the results showed that within a ground tilt angle not exceeding 1. 5°, the instrument achieves an accuracy of 3 000 divisions with a maximum permissible error (MPE) of less than 0. 75 kg in any tilt direction.
