摩托车减震器验收标准

目前国内摩托车减震器规格型号繁多,其质量也千状百态,加上一些总装厂缺少必要的检测设备,不遵循检测标准,因而不问其阻尼力多少和示功图是否合格,只要不漏油、外观漂亮、手感好、价格低就是好产品而用之,这种仅凭人的感觉来检测,其合理性可想而知.

Theoretical analysis and experimental investigation of a high-performance viscoelastic material shock absorber

To improve the performance of traditional mechanical shock absorber, a new type of high molecular polymer is formulated and applied to overloaded vehicle shock absorber. According to the operating principle of high-performance viscoelastic material shock absorber, the geometrical structure of shock absorber is designed and machined. Then its theoretical model is derived by using analytical method, and the impact test is carried out on high-performance viscoelastic material shock absorber. The results show that experimental and theoretical damping force curves have good agreement, which validates the credibility of theoretical model. The investigation provides a potential way to enhance damping performance and increase vehicle load.

耐高速冲击阻尼器设计与试验研究

为实现高速运动设备在阻尼器作用下以低阻抗力、短距快速制动缓冲的目的,降低高速冲击对设备的损伤,该文设计了一种耐高速冲击阻尼器,通过对阻尼器内部结构进行优化设计,并采用缓冲垫加气液阻尼器的多级缓冲方式消除高速冲击瞬间产生的高峰值力,从而降低对运动装置的瞬时冲击值。首先基于气液阻尼器设计了耐高速冲击阻尼器的基本结构,然后通过对阻尼器进行静态压缩试验和超高速冲击试验,测得了冲击过程中阻尼力和缓冲位移,并根据试验结果对阻尼器设计参数进行修正,优化了内部结构,最后在使用现场进行了实际测试,获得测试结果并进行分析。结果表明,该耐高速冲击阻尼器可满足重量为30 kg高速运动装置以30 m/s速度短距快速制动缓冲、且最大阻尼力值不超过40 kN要求。
