Abstract:
In order to study the cooling proeess the temperature field ealeulation and analysis area first, andthen temperature field results data in the form of temperature load in structure analysis. Utilizing the general finite element analysis soltware ANSYS thermal stress forming proeess of TC4 titanium alloy droplets depositionchanges are simulated. Based on the parametrie design language APDl of ANSYS finite element analysis model, adopt the way of indireet coupling simulation of the thermal stress, the researeh on muli - laver droplet in.ternal residual stress distribution alter cooling to room temperalure , and a new layer when the droplet drips andoriginal cooling region has been completely between the residual slress distribution. The result shows that thefinished temperature diflusion degree of molten droplels is small in the equivalent temperature from differenttime ; Afer a period of time after cooling, heat from the droplet area to have the cooling area, temperature fur.ther proliferation ; The last is close to room temperalure. From the verieal and horizontal analysis of stress andstrain , lt can be seen the subsequent droplet drip area middle sag down , eontraction deformation emerge. Between different lavers in horizontal direetion, the temperature differenee is small. The stress distribution ismore uniform at the lale overall cooling.
