摘　　要：为了解决引信机电保险装置在设计阶段时性能设计和可靠性设计顾此失彼的问题,提出了基于引信机电保险装置的可靠性与性能一体化设计方法。根据引信机电保险装置工作原理,筛选出对机构性能可靠性造成影响的关键设计参数及干扰因素,并基于性能仿真模型建立响应面模型及考虑干扰因素浮动情况下的可靠性仿真模型。以性能指标和可靠性指标为约束及由机械保险及电保险性能输出构成的价值函数为优化目标,构建一体化设计的基本优化模型。采用蒙特卡罗模拟的方式对优化模型进行求解。优化结果表明:在关键设计参数启动力矩、充放电时间常数为27.98 N·m、3.34×10^(-4)的情况下,性能输出仍在指标规定范围内,可靠度相比于原始值增加了3.84%,达到设计可靠度要求,验证了该方法有效地结合引信机电保险装置的性能设计和可靠性设计。To address the issue of balancing performance design and reliability design during the design phase of the fuze electromechanical safety device,an integrated design method for reliability and performance was proposed.Based on the working principles of the fuze electromechanical safety device,the key design parameters affecting the mechanism’s performance reliability were identified as starting torque and charge-discharge time constant.Internal disturbance factors included rotational inertia of the balance pendulum,friction coefficient of the rotating shaft,gear meshing efficiency,and reactive force characteristic coefficient.External disturbance factors included speed disturbance and ripple interference.Using the performance simulation model,Latin hypercube sampling was employed for experimental design,and a dataset was constructed to establish the corresponding response surface model.Considering the fluctuations of disturbance factors,a reliability simulation model was developed.With reliability indices as constraints and the value function of multiple performance outputs as the optimization objective,a basic optimization model for the integrated design of the fuze electromechanical safety device was constructed.The Monte Carlo simulation method was used to solve the optimization model.The optimization results show that when the key design parameters—starting torque and charge-discharge time constant—are 27.98 N·m and 3.34×10^(-4),respectively,the performance output remains within the specified range.The reliability increases by 3.84%compared to the original value,meeting the design reliability requirements,which verifies that this method effectively combines performance design and reliability design.
