摘　　要：为了提高深松机作业过程中土壤疏松效果,降低机具的工作阻力,选用1SZ型振动式深松机,在土槽试验平台中进行了相应的振动减阻机理试验研究。首先设计了基于LABVIEW的软件测试系统,选取了扭矩、拉力、角度传感器等传感器及NI主机,基于五杆测力原理,构建了测试硬件系统,并选取机具的前进速度V0、振幅a=R s i nε和振动角β这3个主要因素进行三元二次回归正交旋转组合试验。试验表明:振动角对试验结果影响最大;得出的回归方程表明:当机具前进速度0.75m/s、振动幅值为7.5mm、振动角度为-15°时,试验指标机具工作阻力达到最小值3.975k N。The 1 SZ oscillating subsoiler was used to research on the mechanism of vibration reduction mechanism in the test platform in order to improve the soil porosity in the process of deep loosing machine, and reduce the working resistance of the machine. The software testing system was designed based on LABVIEW, and the sensor of the torque, tension, angle sensor and N1host were selected. Based on the principle of the five bars, the hardware system was constructed. The forward speed V0, amplitude α = Rsinε and vibration angle/3 of the three elements of the machine were selected to carry out the orthogonal rotation experiment of Tri Quadric. The experimental results show that the influence of vibration angle is the most important. And the regression equation was obtained, and when the speed of the machine forward speed was 0.75 m/s, the vibration amplitude was 7.5mm, and the vibration angle was -15 °, the working resistance of the ex- periment was minimum 3. 975kN.
