Optimized design of electric shovel working device structure based on BLISCO framework
In order to find a design solution that meets all the performance requirements while enabling the minimal trade-offs between different objectives
the bi-level integrated system collaborative optization (BLISCO) method based on approximate models is applied to the optimal design of the electric shovel structure. Firstly
a parametric model of the electric shovel was created
sample points were collected through a design of experiments that were used to screen design variables and approximate models of working devices
then a mathematical model for multi-objective optimization was developed by combining the approximate model with BLISCO method
multi-objective optimal design of the electric shovel working device was carried out at the second-generation non-dominated genetic algorithm and sequential quadratic programming were used at the system level and subsystem level
respectively. The optimized parameters were simulated again
and the results show that while solving the above problems
the hoist force and crowd force were reduced respectively by 5.4% and 6.13%
and the angle between the stick and the wire rope was increased by 1.4%. Finally
the electric shovel working device test platform before and after the optimization was built for testing and the correctness of the optimization results was verified.
