| 摘 要： | 为了得到机械设计时可遵循的节能基本原则,采用能量分析方法对功率方程中以周期函数表示的系统势能变化率、系统动能变化率、其他输出力消耗功率、无用功率进行逐项和综合分析,求证得到引起机器输入功率匹配较高和功率没有得到充分利用的原因与机械设计节能基本原理。分析表明,在设计机械系统时,只要使各种能量和功率分别为常量或在最小范围内变化,或者使系统能量和系统功率为常量或在最小范围内变化,则维持系统正常工作所需输入功率将会降低,系统能量将得到充分利用。通过工程实际应用,证明该原理具有较好的节能效果,适用于机电类节能产品设计。

| Abstract: | To find out and verify the basic energy-saving principles of machinery design,based on energy analysis methods,the potential energy changing-rate,the kinetic energy changing-rate,the output force consumed power and the useless power,which are all represented by some periodic functions,are individually and synthetically analyzed.The causes of input power high-matching and the failure of full-utilization are extracted,and the basic energy-saving principles are presented and proven theoretically.In order to en... |
