针对某公司研制的重型商用车驾驶室振动舒适性不理想的状况, 进行试验样车与对标车主观舒适度评价与减振器温度变化对比试验, 并对相关参数进行理论分析, 诊断得出试验样车驾驶室前悬置存在隔振效果不明显的问题, 在分析对比试验样车与对标车悬置参数选取及考虑改进成本的基础上, 提出优化试验样车驾驶室前悬置参数的建议, 并对优化后的样车进行主观舒适度评价与实车道路试验验证, 得出参数优化后的样车舒适度改善明显.
針對某公司研製的重型商用車駕駛室振動舒適性不理想的狀況, 進行試驗樣車與對標車主觀舒適度評價與減振器溫度變化對比試驗, 併對相關參數進行理論分析, 診斷得齣試驗樣車駕駛室前懸置存在隔振效果不明顯的問題, 在分析對比試驗樣車與對標車懸置參數選取及攷慮改進成本的基礎上, 提齣優化試驗樣車駕駛室前懸置參數的建議, 併對優化後的樣車進行主觀舒適度評價與實車道路試驗驗證, 得齣參數優化後的樣車舒適度改善明顯.

According to company developed a heavy commercial vehicle cab vibration comfort is not an ideal situation, test-ing and benchmarking sample car subjective comfort evaluation and shock absorber temperature change contrast test, then an-alyzes the relevant parameters, it is find that the test vehicle cab suspension of vibration isolation effect is not obvious prob-lems, based on the analysis of contrast test vehicle and benchmarking vehicle suspension parameter selection and considera-tion of cost improvement, the author suggest optimist suspension parameters, and then evaluate the comfort prototype and the real vehicle road test, after parameter optimization of vehicle comfort is improved obviously.
