Design and Preparation of Titanium Alloy Springs for Automotive Vehicles
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.
