【摘要】 钛合金弹簧替代钢制弹簧应用于机车悬架弹簧可以减重40%～60%，而且钛合金弹簧具有良好的耐蚀性和阻尼特性，不仅能够抵御恶劣环境的腐蚀，增加机车的行驶里程，还能增强机车的操控性和乘架的舒适性。通过赛车用悬架弹簧实例，详细介绍TB9钛合金弹簧的设计方法和制备过程。计算得到钛合金悬架弹簧的螺旋角为9.45°，已经超出弹簧设计国家标准范围，因此对公式进行了修正。此外，还研究了温度对TB9钛合金弹簧刚度的影响。研究发现，随着温度的上升，TB9钛合金弹簧的刚度逐渐下降。更多还原

【Abstract】 Replacing steel springs with titanium alloy springs can reduce weight by 40%-60% when applied to suspension springs. Titanium alloy springs have good corrosion resistance and damping performance, which not only increase the mileage, but also make the vehicles more controllable and comfortable. Through an example of suspension springs used in racing cars, this paper will provide a detailed introduction to design and prepare TB9 titanium alloy spring. The calculated helix angle of TB9 titanium alloy suspension spring is 9.45°, which exceeds the range of steel spring design standards. So the design equations for titanium alloy spring have been revised here. In addition, the influence of temperature on the TB9 titanium alloy spring rate is investigated. With the increase of temperature, the TB9 titanium alloy spring rate decreases gradually.更多还原
