一些先进国家的钢琴标准中规定“击弦机装置在钢琴上,要连续击弦20万次,检查有无影响使用的缺点”。我国轻工业部领导也多次指出,在钢琴生产中要增加震奏工序。但是,过去由于我国不生产钢琴震奏设备,给制定、执行上述标准及贯彻有关指示精神带来很大困难。为此,北京乐器研究所在上级主管部门的支持下,经过一年多的努力,研制成功了具有我国特点的88J—1钢琴震奏机。该机设计合理,性能良好,造价低廉(每台售价5900元),很适合在国内厂家推广使用。
Some advanced countries, the piano standard stipulates that “struck string machine installed on the piano, to be a continuous string 200,000 times, check whether the impact of the use of shortcomings.” The leaders of the Ministry of Light Industry of our country also pointed out many times that it is necessary to increase the process of the earthquake-strikes in piano production. However, in the past, our country did not produce piano-playing equipment, which brought great difficulties in formulating and implementing the above standards and implementing the spirit of the directives. To this end, Beijing Musical Instrument Institute in support of the higher authorities, after more than a year of hard work, developed a 88J-1 piano featuring the characteristics of our machine. The aircraft designed, good performance, low cost (price 5900 yuan each), it is suitable for domestic manufacturers to promote the use of.
