| Abstract: | Based on virtual prototype technology and 3D flow field theory, a model for flow races of impeller blades in a hydraulic torque converter is set up with 3D software, Pro-E. Inside flow fields of impeller blades of torque converters used on model YJ380 dozer and forklifts are simulated and analyzed with computationed fluid mechanics analysis software FLUENT. Speed and pressure distributions in flow race field of impeller blades are calculated under two work conditions and influences of outlet angle, a key pa... |
