摘　　要：为对某轻型火箭炮液压系统进行轻量化升级,进行典型运行工况辨识,基于AMESim软件对液压系统整机建模和仿真,并通过温升试验验证仿真模型的准确性。采用主要目标法筛选出热平衡关键影响因子,并分别研究其对液压系统热平衡的影响规律,结合二维退元法提出最优配比方案。结果表明:整机仿真与温升试验结果误差不超过1.55℃,验证了模型的准确性。油箱体积影响液压系统达到热平衡温度的时间和温升速率,对热平衡温度大小影响可以忽略,而散热器散热能力对三者均有影响。最优配比方案在原散热系统基础上减轻19.7%,达到减重目标。该方法成本低、改动小,为关键影响因子灵敏度量化分析奠定基础,对其他液压系统轻量化具有参考意义。In order to reduce more weight of the hydraulic cooling system in a light rocket launcher,the typical operating condition is identified.A hydraulic model is established and simulated by the AMESim software,and a temperature rise test is conducted to verify simulation accuracy.Two key influencing factors of the thermal effect are picked by the main objective method,and how they affect the thermal balance of the hydraulic system are studied respectively.The optimum scheme is proposed by the two-dimensional withdrawal method.It is shown that the maximum deviation between the results of the overall system simulation and temperature rise test is 1.55℃,thus verifying the accuracy of the model.Hydraulic tank volume affects the time to thermal balance and the speed of the hydraulic coo-ling process,but hardly the thermal balance temperature.However,the heat dissipating capability of the cooling radiator affects all the three factors.The optimum scheme is 19.7%lighter than the original hydraulic cooling system,and achieves the weight reduction goal.The method is low cost and involves small changes.It can serve as the basis for the quantitative analysis of critical factor sensitivity and support the research on the weight reduction of other hydraulic systems.
