Researches show that the drive force characteristics of the electric tractor drive system based on series DC motor is close the ideal characteristics, the curves are concave, low speed with constant power, and high speed with constant torque; the electric tractor has large working speed under different shifts, but the extensive coincidence speed shows that the variable ratio of the gear is unreasonable; the maximum climbable gradient of this electric tractor is more than 30%, and does not need frequent shift when working for its extensive climbable gradient; there are many influence factors of continuous working time, which the more obvious factors are working speed and working load, the working time increases with the increase of the working speed and working load.2. Simulation researches on the drive characteristic of the electric tractor.
研究结果表明:基于串励直流电动机(来源:ABC21论文网www.abclunwen.com)的电动拖拉机电驱动系统的驱动力特性场接近理想驱动力特性场,其各挡下的驱动力特性是一组下凹的曲线,低速恒转矩,高速恒功率;同一行驶速度下所对应高挡驱动力大于低挡驱动力,这是由电机的调速特性决定的;电动拖拉机各个挡位下具有较广的稳定作业速度范围,但是各个挡位之间速度重合的范围较多,说明所用变速箱变速比与电动机匹配不合理;电动拖拉机最大爬坡度达到30%以上,并且各挡爬坡度变化范围较广,作业过程中不需要频繁换挡;影响电动拖拉机连续作业时间的因素较多,其中作业行驶速度和作业负荷影响最为明显,作业负荷越大,连续作业时间就越短,作业速度越快,连续作业时间就越短。2、电动拖拉机驱动特性仿真研究。

In the one half part, according to the strontium nature, thermodynamic calculation of correlative reaction and the principle of the vacuum aluminothermy reduction process, with the laboratory findings of preparation strontium by vacuum aluminothermy reduction compared and analyzed in different parameter conditions, a variety of factors which effect the decomposition rate of SrCO_3 and the percent reduction of strontia are gotten out. The factors include that the decomposition rate of SrCO_3 is influenced by different addition and pressure. They also include that the percent reduction of strontia is influenced by excess coefficient of reducing agent aluminium powder, the particle size of raw material or reducing agent, the pressure of barbecuing, temperature and reduction time. According to those, we can draw the conclusion as follows:(1) Decomposition temperature of SrCO_3 is decreased by adding carbon and alumina in different degree.(2) With quantitative carbon added under the vacuum condition, the decomposition temperature of SrCO_3 is decreased obviously, which can fall 150℃ compared with atmospheric pressure.(3) In keeping 1150℃ of 2.5h, under the 5Pa vacuum condition, the decomposition rate of SrCO_3 nearly keeps in 99% steadily.
在前半部分的真空铝热还原法中,根据锶的性质、相关反应的热力学计算及真空铝热还原法原理,通过对不同参数条件下的真空铝热还原法生产金属锶的实验结果的分析比较,得出了影响SrCO_3的分解率和氧化锶的还原率的种种因素,具体因素包括不同添加剂、不同气压对SrCO_3分解率的影响,还原剂铝粉的过量系数、原料与还原剂的粒度、制团压力、温度和还原时间等对氧化锶还原率的影响,得出具体结论如下:(1)添加碳和Al_2O_3能不同程度的降低SrCO_3的分解温度;(2)真空条件下加入一定量的碳可显著降低SrCO_3的分解温度,比之常压下可降低150℃之多;(3)在1150℃恒温2.5h、真空度达到5Pa的条件下,SrCO_3的分解率几乎保持稳定在99%;(4)氧化锶的还原率随还原剂过量系数的增大而增大,但是趋势越来越小,当过量系数超过25%后,氧化锶的还原率几乎不再增加;(5)氧化锶的还原率随原料与还原剂的粒度的变细而增加;(6)氧化锶的还原率随制团压力的增加而增加,但超过一定值后,氧化锶的还原率反而会下降;(7)氧化锶的还原率随还原温度的升高而增加;(8)氧化锶的还原率随还原时间延长而增加,在本实验条件下,超过2.5h趋于稳定。
