8 years of time, more than 700 a day and night stick
and bitter, 160 model calibration tests, tens of thousands of kinds of test data
acquisition, industry the earliest of "three high" calibration of the team, the
establishment of industry first "three high" calibration bench... This series of
labels, and the wind, rain and snow, gradually sink into the "three high" Yuchai
calibration test team image. This is a group of heroes who shoulder the fate of
the national industry.
From the beginning of 2005, Yuchai every year, high
temperature plateau, alpine calibration test. In order to achieve the best
results, the control engineer, design engineer, application engineer, test
technicians and professional test driver team of young, like a flock of
migrating birds, from south to north, and from the north to the south. However,
relative to the birds always looking for the most comfortable living
environment, they are more like a group of anti migratory birds, the law of the
season ahead. In the summer, they stepped into Turpan Basin, climbing on the
Qinghai Tibet Plateau; in winter, they go to the north of the ice and snow, Mohe
polar.
A battle to fight
July 23, 2012, midsummer. When you hide in the air by
enjoying the cool when, early in the morning, Yuchai Engineer Yang Fangzi will
lead the first batch of the team set off from the Guangxi Yulin. Calibration of
the three "rising star" preparing to test the first station - years ago trapped
Chinese legend character Sun Wukong Flame Mountain, here they will Yuchai engine
high temperature calibration experiments.
5 days, nearly 4000 kilometers of the long journey, the
team a line finally arrived at the destination. In Turpan Basin in the flaming
mountains, in "journey to the west" in the full description: 80 in the flame
mountain barren cliff, crimson yunzhengxiawei, like lounging in the Gobi desert
of volcanic. The reality of the Flaming Mountains, although not Wu Chengen's
dangerous, but also be threatened by growing crises. "When there is a time after
the flame mountain hot center" alchemy furnace ', I specifically looked at the
stand in the giant of the mercury column, 73 degrees. There's no problem with
this fried egg." Yuchai Engineer Ye Shengbin smiled said, he has for four
consecutive years in three calibration, with rich experience, can be regarded as
is "old" of all corners of the country.
Experiment is hard. Compared with the Hainan special
test field, Turpan region of high temperature, the entire month of August with
the highest average temperature above 42 DEG C, the highest temperature in the
afternoon can be reached 48 degrees Celsius, and the air is dry, hot and humid
environment worse. During the experiment, some conditions are not allowed to
open air conditioning, in order to avoid wind resistance is too large, the
windows are closed. "Once the air conditioner is turned off, the car becomes a
veritable stove.." Yang Fangzi said.
For the first time to join the young Electronic
Engineer Du Yu three calibration test, this test is dangerous. Have a test car
along the highway rapid return, a sudden strong wind carrying a pebble, through
the window is not strict, straight shot into the cab, was crushed his right
lens, fortunately, no injury to the eye. The only 24 year old young man, just
from Beijing Daxue Aerospace graduated two years, on the spot in a cold sweat.
But afterwards, he smiled and said: just, this pair of glasses for four years
can finally 'retire', before still not willing to."
In order to ensure the Yuchai engine in any harsh
environment and mode of operation can be normal operation, this group of young
80 after the team almost torture yourself doing all kinds of test. To calibrate
the passenger car in the high speed road of thermal protection function, in the
vehicle loaded state, they in the high-speed road will speed as possible
increased to maximum. This is extremely dangerous, a sharp turn may lead to
fatal car crash. One time during the high-speed test, the vehicle to the maximum
speed of more than 20 minutes, suddenly, the tester smelled a strong smell of
diesel. Parking check, found the injector return tubing serious leakage,
followed, they found a large number of coolant leakage. Upon examination, the
original is subject to the influence of terrain condition, vehicle running
quickly driven by strong winds, rolled up roadside scattered pebbles, the tank
busting the five or six holes, tire also appeared cracks. Everyone is seen in
front of the "horror" scared the daylights, however, will be towed to a service
station repair. They began to the rest of the test.
In this field to fight the battle, they won. After
nearly 20 days under the environment of high temperature calibration test,
matching of Xiamen Golden Dragon, Golden Tour, Futian, Liuzhou Automobile,
Dongfeng, North Ben, a number of car manufacturers a total of eight models in
the high temperature environment of driving, power and overheating protection
function basically reached the optimization, key parts of the various models of
engine cooling systems and also in high temperature environment were fully
validated, provide a large number of experimental basis for the future design
work.
Eat also individual power live
And the high temperature calibration tests carried out
simultaneously, and the plateau calibration experiments on the Qinghai Tibet
Plateau. This test, Yuchai has selected three sites, respectively Golmud
suburbs, Nachitai and xidatan
