Performance Optimization Design Based on Reliability for Constant Pressure Variable Pump
First of all,the paper analyzes the work of the constant pressure variable pump,establishing its working model,and deriving its transfer function when it is working.Expression of the constant pressure variable pump performance indicators (such as adjustment time and overshoot) could be gotten after the simplification of analysis of the transfer function; also by analyzing the performance expression the key parameters that affect the performance could be identified.Second,the paper analyzes the composition of the reliability of the constant pressure variable pump,establishing its reliability model,deriving the reliability expression.After analysis if the reliability expression,main influencing parameters are identified.Finally,coupling parameters,that not only affect the hydraulic pump performance,but also impact the reliability of the hydraulic pump,are confirmed through analysis.The parameters are also optimized to get the optimal value,so as to achieve the design requirement that to design the pump with both high performance and high reliability.By analyzing the performance and reliability with the optimized parameters,it can be concluded that the proposed design method is practical and reliable,reaching the maximum extent to meet the design requirements.
