Calculation methods for main diesel engine output at sea trial 海上試航主柴油發(fā)動(dòng)機(jī)輸出功率的計(jì)算方法
By analyzing the engine driving torque characteristics and the transmission inertia torque while speed ratio is changed under transient condition , a new synthetic control algorithm is developed which can approach engine target torque by compensating engine output torque with transmission system inertia torque 通過研究無級(jí)變速傳動(dòng)速比變化時(shí)的慣性矩,提出了一種新的控制算法,采用傳動(dòng)系的慣性矩來補(bǔ)償發(fā)動(dòng)機(jī)的輸出轉(zhuǎn)矩,以獲取目標(biāo)驅(qū)動(dòng)轉(zhuǎn)矩。
Saturation vapour pressure of internal combustion engine under actual operation conditions is expressed as the multinomial by using least square method , which facilitates the calculation of rectifying coefficient of engine output and fuel consumption as well as the fabrication of computer programme for such calculations 摘要介紹了用最小二乘法擬合方法,將內(nèi)燃機(jī)現(xiàn)場環(huán)境狀況下飽和蒸汽壓表示為多項(xiàng)式形式,為計(jì)算功率和燃油消耗率校正系數(shù),并為此而編制計(jì)算機(jī)程序提供方便。
