at the same time, experiment shows that pitch has important effect on spring's rigidity . the greater the spring rigidity, smaller is the pitch's effect on coefficient of damping and spring's rigidity 同时沥青对弹簧刚度变化有明显的影响,从实验结果可以看出,弹簧刚度越大,则沥青对其阻尼和刚度的变化影响越小。
these polypropylene cone material with butyl rubber surround materials provide the best possible long-term spring rigidity, ensuring consistent linear cone motion for many seasons 独特的聚炳烯低音盆配抗紫外线丁基橡胶复合折环,提供持久稳定的弹性刚力,保证各种恶劣环境下音盆稳定的线性位移,赋予音盆极为优异的频率响应。
in the process of building model, the method of using experiments to collaborate with computer to acquire parameters was used . the front wheel orientation parameter, the absorber damp speciality and the quality of parts were all acquired by actual measure . the spring rigidity etc are acquired by calculation 本文在模型建立过程中,采用试验与计算相结合的办法获取各种参数,前轮定位参数、减振器阻尼特性、零部件的质量均通过实际测量获得,弹簧刚度等通过计算获得。
using matlab, the step response characteristics of the valve in the elevator system is simulated, comparing the effect of its performance with different structure parameters of the pipe rupture valve, such as hydraulic resistance, diameter of the valve, and spring rigidity, and comparing the valve's dynamic performance under different operating conditions, such as environment temperatures, number of passengers, and emergencies of the hydraulic system, so the paper offers a general and systematic analysis for the pipe rupture valve of the elevator system 另外,在液压电梯不同的工况下,对该阀的动态性能进行了仿真对比研究,如不同环境温度、不同乘客人数、不同液压系统意外,以及不同的油液体积弹性模量,比较全面系统的分析了限速切断阀在电梯系统中的性能,根据这些仿真结果,可以分析该阀正常工作的工况要求和环境要求。
