Optimum Design of Luffing Mechanism for Gookma Rotary Drilling Rig

Optimum Design of Luffing Mechanism for Gookma Rotary Drilling Rig

Guide：

The essence of Gookma's optimal design for the luffing mechanism of the rotary drilling rig is to select the design variable values under certain constraints. Make the objective function value reach the minimum (minimum). The optimization design mainly includes the following three aspects:

1.Modeling techniques for optimal design problems
How to abstract an actual design problem into an optimal design problem and establish an optimal design mathematical model that meets the actual design requirements is an extremely critical issue for complex rotary drilling rig systems.
The optimal design of the rotary drilling rig mainly includes the optimal design of the kinematics and dynamics of the mechanism, the optimal design of the structural parameters, and the optimal design of the components of the rotary drilling rig.

2. Optimization design problem solving techniques
Most of the rotary drilling rig optimization problems are constrained nonlinear programming problems, and the traditional solving methods mainly include random direction method, compound shape method, feasible direction method and penalty function method.
Genetic algorithm is a random search algorithm based on natural selection and genetic mechanism in biology. It does not rely on gradient information, but simulates natural evolution process to search for the optimal solution. It has good global search performance and has been widely used in the field of structure.

 

3. The design of Gookma rotary drilling rig luffing mechanism should meet the following requirements:

●Structure requirements: simple and compact, the weight of the machine as light as possible.

●Location requirements: with a wide range of operation radius adjustment, the specific value depends on the type of rotary drilling rig. The hydraulic crawler rotary digging rig is transported by trailer, and its transportation state meets the corresponding requirements of the state for the height of cargo loaded by vehicles in road transportation.

●Movement requirements: in the process of amplitude, the working device moves smoothly, no interference, no dead point, no self-lock.

●Dynamic requirements: Due to the large transmission torque, the lug mechanism should have good force transmission performance and high transmission efficiency. The working stability of hydraulic cylinder should be ensured in the process of amplitude variation.

●Construction safety requirements: Rotary drilling rig belongs to large pile machinery, and it is required to have good safety in the construction and transfer process.
