摘要
共振式道路破碎机车架承载复杂且要求较高,而减轻车架质量降低油耗成为一个亟待解决的问题。分析车架承载,确定共振破碎机不同工况下的载荷形式及大小。建立共振破碎机车架的有限元模型,计算模拟3种工况实际承载与约束条件下的应力应变。根据车架结构的应力应变分布情况,从结构轻量化角度建立车架优化的数学模型,并采用罚函数内点法进行优化计算。结果表明在满足车架刚度、强度和模态要求的基础上,车架质量减轻了27.29%。
The resonance machine floor slab crusher frame carries complex and higher demanding load, and the problem about reducing the weight of the frame is urgent to be solved so as to cut down fuel use. With the bearing of frame analyzed, both the form and size of load are determined in different working condi- tions. A finite element model for the resonance machine crusher frame is established, then the stress and strain of whieh is calcu-lated and simulated under actual load and constraints in three working conditions. Based on the stress and strain distributions on frame structure, optimization design is started from structure lightweight, and a mathematical model about frame optimization is set up and calculated by an interior-point method of penalty function. The results show that the mass of frame decreases by 27.29% , on basis of satisfying the conditions of its stiffness, strength and modal.
