Comparative analysis and optimization of T and I cross sections of crane hook using by two physics-inspired algorithms

Abstract

Istraživačko-razvojni centar Alfatec d.o.o., Niš (Srbija) 2 Fakultet za mašinstvo i građevinarstvo u Kraljevu, Univerziteta u Kragujevcu, Kraljevo (Srbija) U ovom radu predstavljene su analiza i optimizacija geometrijskih parametara T i I poprečnih preseka dizalične kuke, posmatrane za najkritičnije mesto konstrukcije kuke. Smanjenje površine poprečnog preseka dizalične kuke postavljeno je kao glavni cilj u ovom istraživanju. Kao funkcije ograničenja posmatraju se naponi u karakterističnim tačkama najkritičnijeg poprečnog preseka, sračunati prema Vinkler-Bakovoj teoriji, a takođe su postavljeni i određeni geometrijski uslovi. Za metode optimizacije izabrana su dva metaheuristička algoritma zasnovana na zakonima fizike, algoritam pretrage naelektrisanja sistema (CSS) i algoritam razmene toplote (TEO), korišćenjem MATLAB softverskog paketa. Osnovni cilj istraživanja je da se pokaže da predloženi poprečni preseci ostvaruju značajnu uštedu u odnosu na standardno izvođenje dizalične kuke, pri čemu je posmatrana jedna standardna nosivost. Oba posmatrana poprečna preseka su analizirana u dve varijante, pri čemu je izvršena i komparacija njihovih rezultata optimizacije, kako bi se pokazalo koja od njih ostvaruje najbolje rezultate. Takođe, izvršena je i komparacija primenjenih algoritama optimizacije.

Special Hook Design for Hatch Cover Stocking Gantry Crane, Strength, Numerical Analysis under Static Loading

“…During maintenance and change, no change will occur in the mechanical properties of the box pro le material of the hatch cover stocking gantry crane, as it will not be welded. This, in turn, found that the strength values will be higher and safer than other studies [21][22][23].…”

“…In other studies, the welded connection was made in the hook profile [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. For this reason, corrosion occurring in welding connections, etc.…”

“…This will extend the service life of the hatch cover stocking gantry crane. A case of corrosion occurring in the hook or eyebolt or the need to replace the hook caused by careless use arises [13][14][15][16][17][18][19][20][21][22][23][24]. In this case, the hook or eyebolt will need to be cut from the welding areas and boiled again.…”

Optimization of suspension of rail vehicles with coil springs using marine predators algorithm

“…Solving practical problems of design and optimization in engineering today is most often based on the application of different optimization algorithms. 14 There are many examples of successful application of optimization algorithms in solving problems of structural design of machine elements and constructions, such as those presented in Pavlović et al, 15 Abderazek et al, 16 Bižić et al, 17 Pavlović et al, 18 and Atanasovska and Momčilović. 19 Recent years, one of the most popular algorithms in solving the engineering and technical problems is Marine Predators Algorithm – MPA.…”
