摘要
为了提升振动压路机冷却风扇的性能,提出采用优化冷却风扇安装位置的方法。通过调整冷却风扇与导风罩之间的相对位置,寻找冷却风扇性能参数噪声风速比的最小值,实现振动压路机冷却风扇性能最优化。对优化后的风扇进行了试验,结果表明:安装位置优化后,风扇的噪声风速比比优化前平均降低1.96dB·s·m^(-1),冷却风扇的性能平均提升15.06%,优化效果显著。
In order to improve the performance of the cooling fan of vibratory roller, a method of optimizing the installation position of the cooling fan was proposed. By adjusting the relative position between the cooling fan and the windshield and finding the minimum value of the ratio of noise to wind speed, the performance optimization of the cooling fan should be realized. The optimized fan was tested, and the results show that the average ratio of noise to wind speed of the cooling fan is 1.96 dB · s · m^-1 lower than before, and the performance is improved by 15. 060/00, suggesting that the optimization effect is remarkable.
