摘要

摘要: 在对某液压挖掘机整机前倾稳定性系数计算过程中,得出法切阻力比λ的变化对挖掘机稳定性有很大影响。为提高挖掘机整机稳定性,减小整机失稳的概率,保证挖掘机正常工作,提出了在法切阻力比变化情况下追求最大稳定性的挖掘机机构优化方法。综合考虑挖掘机的两种受法切阻力比λ变化影响的典型工况,采用遗传算法,编制Visual Basic软件,对反铲液压挖掘机配重参数进行多目标优化。优化得到的结果提高了挖掘机各工况的稳定性,表明了此种方法的有效性和可行性。

Abstract: The calculation of the forward-inclination stability of a complete hydraulic excavator shows that the ratio of normal and tangential digging resistance(marked as λ for short) has great influence on its stability. To enhance its stability and reduce its instability probability,we propose an excavator' s structural optimization method that considers the change in ratio of normal and tangential digging resistance during digging. The genetic algorithm was used to develop the Visual Basic software so as to carry out the multi-objective optimization and design of the counter-balanced parameters of the backhoe hydraulic excavator. The stability coefficient under working conditions is obtained while the ratio of normal and tangential digging resistance is changing. The optimization results meet the work requirements for the hydraulic excavator and prove that our optimization method is valid and feasible.
