Abstract: A platform for testing the excavation resistance of a small-sized backhoe excavator is provided. The testing platform comprises a bucket, a mechanical arm device, a measuring device, a workbench frame, and a control device. The bucket is hinged to the mechanical arm device, which is fixed on the workbench frame; the control device is electrically connected to the measuring device, data acquired by the measuring device is used to construct a force balance equation, and through force analysis, excavation resistance is obtained.

Abstract: An inverse matrix iterative deconvolution method for spectral resolution enhancement comprises the following steps: step 1, sequence convolution and convolution square matrices; step 2, cumulative multiplication of convolution square matrices and convolution kernel function peak broadening; and step 3, peak resolution enhancement. The invention achieves the purpose of narrowing the peak width by multiplying primitive functions by deconvolution matrices. Further, the invention provides a method for constructing a deconvolution identity matrix to achieve the deconvolution effect with an expected precision. The calculation process is fast and controllable with stable and accurate results, and the application range is wide. The method can be used for resolution enhancement of molecular spectra such as Raman and infrared spectra, as well as other spectra with symmetrical peak patterns such as mass spectra, nuclear magnetic resonance, XRD and XRF.
