摘要
针对输送带定节流缓冲制动平稳性差问题,对传统输送带断裂制动液压系统进行优化,提出一种变节流缓冲制动输送带的液压系统。利用AMESim搭建优化后的输送带断裂制动液压系统仿真模型,仿真分析优化系统的平稳制动特性,分析了不同输送带制动初速度和制动总质量对输送带制动位移、制动速度、制动位移-制动力的影响规律。研究结果表明:提高输送带制动初速度或增加制动总质量,输送带制动位移不变,维持在1.0 m以内;制动速度和制动总质量对输送带制动特性的影响规律一致;提高制动初速度或增加制动总质量,液压缸制动力保持恒定值的制动位移区间延长。
Aiming at the problem about the poor stability of broekn belt fixed throttle buffer brake system,the traditional broken belt brake hydraulic system was optimized.A new type of variable throttle buffer brake belt hydraulic system was proposed.The AMESim simulation model of the optimized hydraulic system for broken belt brake was established.The smooth brake performance of the optimized system was verified by simulation.The influence of different initial brake speed and total brake mass on brake displacement,brake speed and displacement-brake force was analyzed.The research results show that:when the initial brake speed is increased or the total brake mass is increased,the broken belt braking displacement remains unchanged,all within 1.0 m.The influence of brake speed and brake mass on the belt brake characteristics is consistent.The braking displacement range of hydraulic cylinder with constant brake force is extended with the increase of initial brake speed or total brake mass.
