摘　　要：针对步行式挖掘机前步行腿在作业过程中的力学边界条件的求解问题．选取了3种典型的作业工况，建立了整机的静力学分析模型，构造了支腿力学边界条件的优化求解模型．并采用二次规划法对其求解。结果表明，该优化方法简单、可靠．为步行式底盘局部结构的有限元分析和结构设计提供了理论依据。Focusing on the problem to solve the mechanics boundary conditions of walker excavator＇s front legs during the working process, after choosing three typical working conditions, the static analysis model of the overall machine is established, and the optimized model to calculate the maximum force is constructed and it is solved by sequential quadratic programming method. The results show that the optimized method is simple and reliable, and it can provide theoretical bases for finite element analysis and structure design of the local structure of the walker chassis.
