【Abstract】 Some characters of thick-wall pipeline with high dynamic pressure (TWPHDP) have been analyzed and the ways to detect its pressure was discussed. It has been proved by certain experiments that the parameters of dynamic pressure in the pipeline can be gained by utilizing its strain signals at pipeline. The result can be used to monitor the condition of fuel system in a diesel engine or the condition of hydraulic system in construction machinery, mine machine and vehicle.更多还原
