The four essentials of
stacker-reclaimer mechanical design are functional principles, parameters,
mechanisms, and structure.
1. The model design of whole machine includes: machine modeling, function
methods, cost composition and cost control; specific principle of each
mechanism, position change of the center of gravity, and change of wheel load;
principle of hydraulic system, electrical design of material reclaiming
technology and procedure, technology and procedure design of unmanned stacker-reclaimer,
electrical interlock and protection; implementation and application of standards
and codes in various regions and countries; machine safety and environmental
protection; reliability and availability of machine.
2. The parameters design of whole machine includes: functional parameter design
of whole machine, geometric parameter design, kinematics parameter design,
dynamics parameter design, etc.
3. The mechanism design of whole machine includes: mechanical design of bucket
wheel, boom belt conveyor, luffing, slewing and traveling devices; principle
design and analysis of each mechanism; means and methods for achieving functions
4. The structure design of whole machine includes: structure load and load
combination, force transmission, strength and rigidity of structure, local
stability of structure; stability of whole machine; calculation of necessary
structural fatigue life.
The key point of the four essentials is that no error or failure is allowed to
appear in the simplified mechanical model and mathematical model and reasonable
cost and performance shall be ensured. And the most important thing is to
incorporate small physics and small algebra into product engineering thus to
realize safety, reliability and durability of machine.
