Numerical simulation for factors influencing performance of glass fiber reinforced PA6 welder shell
Performance of glass fiber reinforced polyamide 6 in welder housing applications was taken an in-depth look.Based on the ANSYS software platform,detailed static simulation and falling ball impact simulation analysis were carried out,aiming to reveal the influence of key parameters such as glass fiber content,glass fiber length-diameter ratio and glass fiber orienta-tion on the performance of the welder shell.In the static analysis,the results show that when the shell is subjected to a tensile force of 2 500 N,the increase of glass fiber content has little effect on the stress strength of the welder shell,but it can reduce the deforma-tion degree of the shell.In particular,when the glass fiber content exceeds 25%,the equivalent stress tends to be stable(about 51 MPa),showing an excellent reinforcement effect.In addition,the orientation of the glass fibers has a significant impact on the perfor-mance of the welder housing.When the fibers are oriented along the X axis and the Z axis and each account for 50%(the direction vector is a2),the equivalent stress of the shell reaches 54.6 MPa,and the deformation is the smallest,only 0.5 mm,which is compara-ble to the shell with 40% glass fiber content.However,the increase of the aspect ratio of glass fiber has no significant effect on the equivalent stress,but it helps to reduce the deformation.Furthermore,through the impact analysis of falling balls,it is found that with the increase of glass fiber content,the equivalent stress of the shell gradually increases,and the deformation gradually decreas-es.It is particularly noteworthy that when the glass fiber content is less than 20%,the welder shell is prone to crack under the impact.However,when the glass fiber content is between 20% and 35%,the shell exhibits excellent impact performance and no cracking.
