Based on regulations both at home and abroad for the strength test of automotive seats and safety belt anchorage, an integrated test bench for occupant restraint system is developed, with which the tests of seat stiffness , safety belt anchorage strength and the performance of head-rest can be conducted. A FE model of the master frame of test bench is built and its strength is analyzed with software ANSYS. The control system of test bench is developed by using virtual instrument technology, and the strength test of seats assembly and safety belt anchorage are performed on the test bench. The results demonstrate that the test bed developed can meet the requirements of relevant test regulations and can be used for the research and development of automotive occupant restraint system.%基于国内外汽车座椅和安全带固定点强度试验法规,开发了可同时进行座椅刚度、安全带固定点强度测试和头枕性能等测试的乘员约束系统综合试验台.采用ANSYS软件建立了试验台主台架的有限元模型对主台架进行强度分析；应用虚拟仪器技术开发了该试验台的控制系统,并利用该试验台进行了座椅总成静强度试验和安全带固定点强度试验.结果表明,该试验台能满足相关试验法规的要求,可用于对乘员约束系统的研究和开发.
