根据气缸工作过程微分方程组和阀片运动微分方程组研究环状阀柱状弹簧的设计问题，包括同级吸、排气阀的比弹簧力设计，双作用同名气阀的比弹簧力设计，阀片质量对比弹簧力的影响，特别研究了弹簧与阀片撞击脱离的问题，提出了弹簧自振频率的新的校核方法。 According to the differential equations of the cylinder working process and the differential equations of the valve disc, the design problems of the annular valve spring are studied, including the spring force design of suction and discharge valves at the same level and the spring force design of double acting valve of the same name, The mass of the spring is compared with that of the spring, the problem of collision between the spring and the valve is especially studied, and a new method of checking the natural frequency of the spring is put forward.
