Automobile Production
I study at the college, at the automobile-construction department. When I graduate from the college I shall become a technician. All specialists in automobile industry dealing with manufacturing automobiles (cars or trucks) must know that the production of the automobile comprises the following phases:
-designing;
-working out the technology of manufacturing processes;
-laboratory tests;
-road tests;
-mass manufacturing (production).
Why is it necessary to know all these facts? It is important to know them, as before the automobile is put into mass production it should be properly designed and the car must meet up-to-date requirements. What are these requirements?
The automobile must have high efficiency, long service life, driv-ing safety, ease of handling and maintenance, pleasant apperance. Also it must be comfortable and ecological. In order to obtain these quali¬ties the specialists should develop up-to-date methods of designing cars using new types of resistant to corrosion light materials. Also it is im¬portant to know computer sciences because computers offer quick and optimal solutions of the problems. Besides they are used for better op¬eration of mechanisms in cars.
Before the car is put into mass production the units of the car are subjected to tests in the Works laboratory and then the car undergoes a rigid quality control in road tests. Why are these tests required? What qualities are required of the automobile? They are needed because the modern automobile must be rapid in acceleration, have smooth acting clutch, silent gearbox, dependable braking and steering systems, de¬pendable ignition system, low fuel consumption and be stable on the road.
