摘　　要：采用两种控制技术对6082铝合金转向节差压铸造中的浇注温度、充型压力、结壳增压压力和结晶增压压力进行了控制,并进行了试样的耐磨损性能和冲击性能的测试与分析。结果表明:与常规PID控制技术相比,采用模糊PID控制技术对转向节差压铸造过程中的参数进行控制,可提高转向节的耐磨损性能和冲击性能,使其室温磨损15min后的磨损体积减小17.6%,冲击吸收能增大16.7%。Two kinds of technology were used to control the pouring temperature, filling pressure, shell pressure and crystallization pressure in the differential pressure casting process of 6082 aluminum alloy steering knuckle, and the wear resistance and impact performance of the samples were tested and analyzed. The results show that compared with the conventional PID control technology, the fuzzy PID control technology for controlling the parameters of the steering knuckle casting process improves the wear resistance and impact resistance of the steering knuckle, and the wear volume decreases by 17.6% after 15 min of wear at room temperature, and the impact absorption energy increases by 16.7%.
