摘　　要：对轮式起重机用安全阀的结构及稳瞬态特性的研究,证明环隙阳尼和振荡式结构的溢流阀,具有良好的稳瞬态特性,适合轮式起重机的液压系统。对先导式溢流阀研究证明:主阀的阻尼结构是改进其性能的关键。A study on the structure of safety valveand its static and transient characteristics for use in wheel loaders has proven that the relief valve with annular gap damping and oscillating structure has good static and transient characteristics and is suitable for the hydraulic system on wheel cranes. The study on pilot type relief valve has demonstrated that the da mping structure of the main valve is the key point in improving its performance.
