Abstract

The invention discloses a novel PV (pressure and volume) test detection device and a novel PV test detection method. A rudder propeller base is integrated with a stern part of a ship body in design according to a pre-outfitting requirement, a working allowance for milling is reserved on an upper plane of the rudder propeller base, alignment and positioning are carried out by adopting the processing method disclosed by the invention after a main ship body is folded, and the processing device finishes milling for the upper plane and a seal groove and drilling for mounting holes on site under deck.

Description

technical field [0001] The invention relates to PV testing, in particular to a novel PV testing and detection device and method. Background technique [0002] ABS is the abbreviation of English Antilock brake system and anti-lock braking system, PV is the abbreviation of English Pressure And Volume pressure and volume corresponding characteristics. [0003] The PV characteristic curve of the wheel cylinder is used in the pressure estimation module of the ABS software. The PV characteristic curve directly affects the accuracy of pressure estimation, the accuracy of the calculated PWM signal duty cycle of the inlet valve, and the calculated opening of the outlet valve. accuracy of time. [0004] The present invention is to measure the PV characteristics of the device under laboratory conditions. It is highly dependent on experimental conditions and cannot be easily moved. Poor adaptability, unable to adapt to specific experimental conditions of different vehicles. [0005]...
