中文摘要随着现代工业的发展，工程构件的服役条件也日趋复杂，传统性能测试判据有时不能真实反映服役特性，常规性能测试都是由慢加载方法测定，如通过拉伸试验和弯曲试验来获取构件耐久度的试验。但实际情况里，由于加载速度的差异，在高速加载条件下，构件的工作过程与慢输入情况下会出现明显不同，对构件的要求也不尽相同，因此就会存在性能检测上的差异，使用高速冲击的动载荷试验的目的在于尽量模拟工程构件的实际工作环境条件，为工程设计提供真实的试验数据。50806

本设计主要从事落锤式摩托车减震器冲击耐久试验台的设计，摩托车的减震器是其关键组件之一，肩负着车辆的好多重要性能：对车身和骑载质量作弹性支撑，决定摩托车的承载能力；摩托车减震器将前后轮连接在车身上，固定住前后轮跳动的轨迹，再通过车把对行驶方向的调节，改善操纵稳定性。

落锤式摩托车减震器冲击耐久试验台的设计涉及力学、传动与控制、测试技术、控制工程等，前叉用冲击试验台的基本思路来源于落锤材料试验机，一方面，它充分利用了落锤材料试验机的动载荷特性，另一方面它创新性的应用到了摩托车前叉减震器当中，他是对现存耐久度测试的补充，是对前叉在冲击动载荷下的特性的测试，满足用质量求发展的企业的需求。

Abstract With the development of modern industry, the service condition of engineering components is complex.The traditional performance testing criterion sometimes cannot really reflect the service features, regular performance test by slow loading determination methods, such as through tensile test and bending test to get the component durability test. But in fact, because of the difference of loading speed, under the condition of high load, and also have different requirements for components, thus there is the differences of performance testing, using high-speed impact dynamic load test is aimed at simulating the actual working conditions of engineering components as far as possible, provide real test data for the engineering design.

This design is mainly engaged in the shock machine shock endurance test bench is designed, motorcycle shock absorber is one of the key components, is shouldering the vehicle's many important properties: to the body and riding load quality elastic support, decided to a motorcycle carrying capacity; Front and rear wheels will be attached to a body, front and beating trajectory, cooperate with handlebar provides direction adjustment, and to improve the steering stability.

The shock machine absorber shock durability test-bed design involving mechanical, transmission and control, testing technology, control engineering, etc., front fork with basic ideas derived from the drop impact test bed of material testing machine, on the one hand, it makes full use of the dynamic load characteristic of the hammer material testing machine, on the other hand it innovative applied to motorcycle front fork of shock absorber, he is addition to the existing durability test, is to the front fork under the impact dynamic load characteristic test, meet the needs of using quality strives for the development of the enterprise.

Key words: shock machine; Motorcycle shock absorber; Control circuit
