摘　　要：针对防滑涂料的抗冲击性能测试需求,设计了两自由度的冲击试验机。采用理论分析、虚拟样机技术、样机实测相结合的研究方法,研究了两自由度冲击试验机的冲量、冲击时间的特性。结果表明,所设计的两自由度冲击试验机的瞬时冲击性能稳定,满足瞬时大载荷冲击的要求。即在下摆臂保持切入角63°,上扬角60°的条件下,冲击试验机的冲击时间约为0.006 s,水平冲量与竖直冲量可以分别达到为142和983.7 N·m,两自由度冲击试验机能够较好地模拟材料所受的双向瞬时冲击特性,能够用于大载荷瞬时冲击测试。The paper designed a 2-DOF impact test machine for non-skid systems.The paper employed virtual prototype, experimental study and theoretical analysis to study the impact characteristic and impact time. The result showed that the designed 2-DOF impact testing machine had excellent impact performance, and can apply to most instantaneous impact. The impact time can maintain 0.006 s, the horizontal momentum reached 142 N·m and the vertical momentum reached 983.7 N·m, when the entrance angle was 63° and the exit angle was 60°. So the designed 2-DOF impact test machine can been well applied to most instantaneous impact test.
