【 摘 要 】

To improve the efficiency of coordinating the lightweight goal and structural performance for excavator boom, a knowledge-based optimization mechanism is proposed. By this mechanism, the stress characteristics in excavator boom can be extracted automatically at first. After that, stress characteristics knowledge can be acquired based on Monte Carlo simulation and processed under multistate constraint. Depending on the cycle operation between knowledge utilization module and optimization module, the strategy of utilizing characteristic knowledge to guide the structural optimization can be realized. Finally, different testing cases are taken in the structural optimization of excavator boom as examples to demonstrate the feasibility and effectiveness of proposed method.
