A us.r-programmable computational/control platform was.developed at the Univers.ty of Toronto that offers.real-time hybrid s.mulation （RTHs. capabilities. The platform was.verified previous.y us.ng s.veral linear phys.cal s.bs.ructures. The s.udy pres.nted in this.paper is.focus.d on further validating the RTHs.platform us.ng a nonlinear vis.oelas.ic-plas.ic damper that has.dis.lacement, frequency and temperature-dependent properties. The validation s.udy includes.damper component characterization tes.s. as.well as.RTHs.of a s.ries.of s.ngle-degree-of-freedom （s.OF） s.s.ems.equipped with vis.oelas.ic-plas.ic dampers.that repres.nt different s.ructural des.gns. From the component characterization tes.s. it was.found that for a wide range of excitation frequencies.and friction s.ip loads. the tracking errors.are comparable to the errors.in RTHs.of linear s.ring s.s.ems. The hybrid s.OF res.lts.are compared to an independently validated thermal- mechanical vis.oelas.ic model to further validate the ability for the platform to tes. nonlinear s.s.ems. After the validation, as.an application s.udy, nonlinear s.OF hybrid tes.s.were us.d to develop performance s.ectra to predict the res.ons. of s.ructures.equipped with damping s.s.ems.that are more challenging to model analytically. The us. of the experimental performance s.ectra is.illus.rated by comparing the predicted res.ons. to the hybrid tes. res.ons. of 2DOF s.s.ems.equipped with vis.oelas.ic-plas.ic dampers.

1母鸡饲喂方案如同育成鸡一样,为了控制体重必须对成年种鸡限制饲料量.不管育成期采用哪种饲喂制度,20周龄后,全部种鸡都应实行每日饲喂制,而不是隔日饲喂制.毫无疑问,种鸡的最佳生产性能有赖于成功的育成管理,世界各地饲养在不同条件和饲喂不同配方日粮的种鸡群的资料表明:当鸡群在育成后期--开产前期--种鸡前期这个转换阶段的体增重最佳时,总能达到较好的生产性能.这时,能量最有可能是最关键的营养素,肉种鸡开产早期能量需要的建议量变异很大,事实上,已报道的数据变异在0.92～1.84 MJ/只/日.
