汽车离合器膜片弹簧的优化设计

膜片弹簧是汽车离合器的重要部件,是由弹簧钢板冲压而成,形状呈碟形。膜片弹簧结构紧凑且具有非线性特性,高速性能好,工作稳定,踏板操作轻便,因此得到广泛使用。本文通过对膜片弹簧建立数学模型,特别通过引入加权系数同时对两个目标函数进行比例调节,并用matlab编程来优化设计参数。通过举例,结果证明在压紧力稳定性,分离力及结构尺寸上优化结果较为理想。

Optimize the design of the diaphragm spring clutch

The diaphragm spring is one of the important parts of the clutch, it stamping by spring steel, shape of a dish. Diaphragm spring has a non-linear characteristic compact, and its high-speed performance is good, stable, lightweight pedal operation, so widely used. Based on the mathematical model of the diaphragm spring, in particular through the introduction of weighting coefficients while the two objective fimction proportional be controled, and use matlab programming to optimize the design parameters. By way of example, the results of the stability of clamping force, separation and structural size optimization are better.
