Table 8 Comparison of straightening methods

From: Virtual straightening of scraper conveyor based on the position and attitude solution of industrial robot model

Straightening method Principle Differences
LASC straightening principle Pushing → Advancing support according to the straightening correction amount → Pushing at full stroke 1. The former uses the straightening correction of Fig. 12, \({RPC}_{n}\) as the moving frame. In the latter, the actual elongation of the hydraulic cylinder corresponding to the \({DPC}_{n}\) in Fig. 12 is taken as the pushing stroke, and the elongation of the hydraulic cylinder corresponding to the \({RPC}_{n }\) straightening correction is taken as the advancing stroke
2. The order of pushing and advancing of hydraulic support is different
Straightening method based on motion law of floating connection mechanism Pushing → Advancing support according to the elongation of the piston rod corresponding to the difference value \({DPC}_{n}\)→ Pushing according to the elongation of the piston rod corresponding to the straightening correction value
