Research And Design Of Non-standard Equipment Flexible Automotive Engine Hot Test Line

With the social development and the continuous progress of science and technology, theautomobile has become an indispensable part of our life, almost every family will have abelongs to own cars, the automobile has become the means of each family tools in daily life.Therefore, it is particularly important for the detection of automobile engine. If the detectionof automobile engine is not in place, the car will bring great harm to yourself even otherssafety and property. So the car engine in the factory, the test must be carried out a full rangeof it, only to meet the factory requirements, the car can be applied to the market. The carengine hot test line has very important practical significance in the detection of automotiveengine.the automobile engine test production line as the research background, through theresearch and analysis of domestic situation, try to form a line of automobile engine heatengine hot test line function, process flow, thermal test line and control system workingprinciple. In order to find some problems existed in the automotive engine hot test. In the carengine hot test line, some of the equipment is backward, automation does not reach thedesignated position, eventually leading to the production efficiency is low, catches up with theace of nternational evelopment. But in detection of automobile engine hot test,for thedetection of themaximum speed, maximumspeeddling speed and torqueis not preciseenough.This first carries on the analysis to theaut mobile engine hot test ineey part of speed,thline speed control system with single loop PID model and the fuzzy PID model ofautomotive engine hot test, through the analysis of the whole system, using fuzzy PID tocontrolvalve opening, so as to control the speed, let the engine hot test line the maximumspeed of more accurate easure the maximum speed, then by adjusting the appropriate P I Dparameters, idling speed andtorque. Then, due to the current industry of automobile enginehot test low line system is old, automation capabilities, this automobile engine hot test of theelectric control and human-computer interface design, so that the automation ability andworking efficiency is further enhanced. Finally, through PLCSIM simulation, Matlab, throughthesimulation to analyze the control requirements.
